    HISTORY OF FAGERHULT 70 years of lighting knowledge

  • Dear Reader, In this issue of the Innovator we celebrate the 70th birthday of Fagerhult. When discussing what these 70 years represent the answer came quickly 70 years of lighting knowledge, 70 years of innovation with focus on creating light that is good for people. This knowledge and innovation journey started with our founder, Bertil Svensson, wanting to give his mother the experience of doing her handicraft in good lighting. What began with a smartly designed floor lamp became our DNA. Our curiosity, innovative mind-set and the knowledge we have built over the years have prepared us for any challenge to come. Challenges in new technologies, new materials and new findings. The past few years we have seen a paradigm shift within the industry that can be summarised with three letters and is spelt LED. As the earth keeps spinning, time doesnt stop and we keep looking into the future to find the lighting solutions of tomorrow. What are the trends in lighting, what is the next step and when? In the meantime, we see more and more new tech-nologies to exploit the fact that LEDs are electronics and that we are able to use the lights and electronics for more than just lighting. For those who dare to look up and think in new patterns, the possibilities with new technologies become greater than the limits. Connectivity is here to stay and it is growing fast. As a result we see the development of smart cities and smart buildings where the lighting system, its electronics and sensors are essentials part of information network. This is happening now and constantly evolving, faster than anyone could have imagined just a couple of years ago. So happy reading to all you innovators!

    Lighting represents almost 20 percent of global electricity consumption according to the International Energy Agency. The future development of society in both developed countries and emerging economies around the world are intimately tied up with the ability to effectively light our cities, workplaces, homes, schools and recreation areas.

    Lighting provides safety and security, provides access to education, enhances architecture, and improves our quality of life. We take it for granted and often notice it only by its absence. However, as cities worldwide develop it is essential to employ new and innovative lighting design techniques and technologies that improve energy efficiency cost and control, that easily can be adapted to local needs.

    light is not only visualLight plays a vital role in our daily lives and is an imperative cross-cutting discipline of science in the 21st century. It has revolutionised medicine, opened up international communication via the Internet, and continues to be central to linking cultural, economic and political aspects of the global society. On 20 December 2013, The United Nations (UN) General Assembly 68th Session proclaimed 2015 as the Inter-national Year of Light and Light-based Technologies (IYL 2015). This International Year has been the initiative of a large consortium of scien-tific bodies together with UNESCO, and

    will bring together many different sta-keholders including scientific societies and unions, educational institutions, technology platforms, non-profit orga-nizations and private sector partners. The Global Secretariat is located at the Abdus Salam International Centre for Theoretical Physics in Trieste, Italy. In proclaiming an International Year focusing on the topic of light science and its applications, the United Nations has recognised the importan-ce of raising global awareness about how light-based technologies promote sustainable development and provide solutions to global challenges in energy, education, agriculture and health.

    light as a drugLight has been known for a long time to enable sight, safety and orientation. But light can do more than enable vision. Light has the power to energise, relax, increase alertness, cognitive performan-

    ce and mood. Light is the most powerful regulator of the day-night-rhythm of people. Every day light exposure adjusts and stabilises the duration and timing of our sleep-wake cycle. Moreover, light is known to be an effective treatment for a variety of conditions that include mental disturbances such as Seasonal Affective Disorder (SAD) and certain kinds of sleep disorders. The ability of light to achieve these various non-visual effects depends on the spectrum, intensity, and tempo-ral pattern of the light, as well as the light-exposure history and preceding sleep behaviour of the individual. Therefore, the optimisation of a Human Centric Lighting solution for a given non-visual effect is only possible when this user context is accounted for. This requires a dedicated and tailor-made design, based on a profound understan-ding of the personal and environmental conditions of the use-case(s). A one size fits all Human Centric Lighting solution does not exist, and one may even do more harm than good when applying a solution beyond the context and scope it was designed for.

    can you see the stars? In most large cities of the world, it is no longer possible to appreciate the beauty of the night sky. Inefficient public lighting both wastes energy and causes light pollution that hides our universe from us. Light pollution is a form of environmental degradation in which excessive artificial outdoor lightings,

    such as street lamps, neon signs, and illuminated sign boards, affect the natu-ral environment and the ecosystem. The wasteful light emitted directly upwards or reflected upwards from poorly-desig-ned artificial light sources can be scat-tered by clouds, fog, and pollutants like suspended particles in the atmosphere. The night sky is thus brightened, leading to a reduced number of stars visible in

    the sky due to a decrease of the light contrast. light over the worldFrom India, Brazil and Iran, to Italy, Cuba and Senegal, throughout the course of 2015 the world will be paying their own local tributes to light with a series of events, lectures and festivals.

    70 years of lighting knowledgeFagerhult is the story of a man who saw the world with new eyes. Who spotted opportunities in technological advancements and in the world around him. And who shared his visions with others like him. 70 years later, our driving forces are

    still innovation and knowledge with a human focus.text amelie bergman | photo fagerhult

    Our story begins at Christmas time. The year was 1943 and a young electrician, Bertil Svensson, had a brilliant idea for a Christmas gift for his mum. He bought an 18.6 mm light-gauge conduit, a bit of cord, a lamp holder and a mains plug from his employer. He asked a local carpenter to turn him a birchwood lamp foot, and found a 60 cm lampshade at the local department store. And then he sat down to assemble his very first light fixture. The result, a floor lamp in the shape of a question mark, was a big hit, bright-ening his mothers crafts room on long, dark winter days. Doing needlework by the light of a floor lamp was not very common in

    those days, Bertil said. I didnt spend a lot of money making that lamp, and when I saw what similar ones cost in the shops, I got the idea that maybe I could make a living making lamps. That was my whole idea. I had no thought at all about organisation, sales technique or distribution. That would soon change. In 1945, Bertil Svensson teamed up with two childhood friends from Fagerhult. Helmer Andersson was a clever designer and production technician at Husq-varna. Harald Ulfenborg was a furniture manufacturer under the Ulferts brand. Together they started Fagerhults Lampindustri in an outbuilding on Bertils family farm in Fagerhult.

    Bertils inventiveness, Helmers tech-nological genius and Haralds contacts in the furniture industry became the foundation of a highly successful home lighting company. It was not an easy time. Europe lay in tatters after the Sec-ond World War and it was hard to obtain materials. But thanks to its neutrality policy, Sweden was in fairly good shape, and soon its industry was running at full tilt. In the beginning, Fagerhult focused on the home market, which was fuelled by the new Swedish welfare model. By autumn 1947, the company had outgrown the outbuilding and it moved to a newly built 98 m factory. Since then that factory has been renovated

  • In 1948, Bertil discovered that there was a new light source a fluorescent tube that produced a great amount of light at very low cost.

    and expanded more than 40 times, now boasting 55.000 m. From the very first lamp, Bertil focused on meeting a human need and solving a problem. Using new materials and solutions, he had found a way to create added value for the user and profitability in his own production. An innovative approach that came to shape Fagerhults future activities and became a part of the companys DNA. In 1948, Bertil discovered that there was a new light source a fluorescent tube that produced a great amount of light at very low cost. Certain that this was the light solution of the future,

    he developed an entire collection of fluorescent-tube luminaires. A decade later, this paid off in Fagerhults first big prestigious order: 5.000 specially designed luminaires for the iconic func-tionalist National Tax Board building in Stockholm, Skatteskrapan. Fagerhult moved into the contract market, quickly becoming a key player in public interiors. In the coming decades, the compa-ny grew steadily in the technical lighting field, although the focus remained on developing and manufacturing home lighting until well into the 1990s. By this time, Fagerhults signature traits of inquisitiveness and industriousness

    had resulted in several innovations that changed the lives of millions of people. The innovative plastic luminaire Fabian, of which more than 4 million were sold, and recessed downlights in the form of the popular Pleiad model, are just a few examples. The courage to develop completely new luminaires based on relatively untested light sources is a shining trend throughout the years. When T5 fluorescent tubes were launched on the market, Fagerhult was one of the first companies to develop luminaires designed for the new light source. Fagerhults T5 luminaires combined

    the T5 light source, electronic controls and effective reflector materials that revolutionised the lighting industry and set a new standard for energy efficiency. When LED entered the scene 15 years later, the company followed the same path, generating as much light as possi-ble, with no compromises. The current head of development at Fagerhult, Leif Norrby, has been a part of the journey since 1978. He states that this uncompromising drive to offer the most benefit for users is still the defining characteristic of Fagerhult luminaires: Delivering superior energy efficiency without compromising on glare reduction and visual comfort is our trademark. Working closely with leading research institutes has given us an advantage in developing proactive solutions lights that make people happier, more alert and more active. Our sustainability concept doesnt just cover energy conservation, environmen-tal impact and working conditions; it embraces the entire human context. In 1969, Bertil who had been the companys CEO since 1949 was invited to take over all shares in the company. This was the beginning of an international expansion that occurred both organically and through acquisi-tions. In the coming decade, Fagerhult established sales offices in Denmark, Norway, the Netherlands and Germany. It also bought out its Swedish competi-

    tor Atelj Lyktan. In 1984, Bertil left the office of CEO. A few years later, Fagerhult was acquired by the Swedish Almedahl Group. In 1993 it was time for the next acquisition, when the investment company Latour, under the leadership of the Douglas family, took over all shares in the corporate group. Latour gave Fagerhult another long-term and committed owner and the Douglas family have remained a major owner even after Fagerhults introduction to the Stockholm Stock Exchange in 1997. Not long after that, Fagerhult estab-lished offices in the UK and the group for the first time surpassed SEK 1 billion in sales. The turn of the millennium kicked off a rapid expansion, and in 2005 Fagerhult opened its big production facility in Suzhou in China. Through sev-eral aggressive acquisitions, Fagerhult became one of the big names in the European lighting industry, not just in terms of technical development, but also in market share. Thanks to the Finnish company, Fagerhult began making inroads in the Russian market, alongside establishments and acqui-sitions in Central and Eastern Europe. Among the biggest acquisitions were Whitecroft Lighting in the UK, Project Lighting in Ireland, Waco in Belgium and Eagle Lighting in Australia. Two other interesting acquisitions LampGustaf in Sweden with its subsidiary Elenco

    and LTS in Germany came to be the cornerstones of Fagerhults extensive focus on shop lighting and outdoor lighting. The operations were divided into three business units with their own manufacturing and development: Fagerhult Professional, Fagerhult Retail and Fagerhult Outdoor. In September 2006, Bertil Svensson received an honorary doctorate at Jnkping University for his distin-guished lifes work as a national pioneer, entrepreneur and leading businessman in the lighting industry and for impor-tant support to education and research in the lighting field. Through the Bertil & Britt Svensson Foundation for Lighting Technology he supported new Swedish education in lighting technol-ogy, which would form the basis of the Lighting Academy. Just a few months later, in November, Bertil left this world at the age of 86. That same year, the Fagerhult Group surpassed sales of SEK 2 billion. In 2015, what had started out 70 years earlier as a three-man company with sales amounting to SEK 13.000 had become a world-wide company with 2400 employees and sales approaching SEK 4 billion. All thanks to Bertil, his mother Elisabeth and her needlework basket.

    e-Sense Tune lighting becomes personalWouldnt it be wonderful to have the lighting exactly as you want it, a light that adapts to your needs and personal preferences? Mimicking daylight, saving energy and energising you? e-Sense Tune does all that, and more. Now its a reality; the truly personal lighting solution.text amelie bergman | photo mats andersson

    e-Sense Tune is a plug & play-system that has been developed by Fagerhults own project team under the direction of Daniel Unoson. It is an innovative, decentralised standalone-system or, as Daniel describes it: Its a truly personal, wireless light-ing control system that suits all applica-tions where one user at a time is allowed to control the light. Its fast to install and easy to control you just install the lumi-

    naires and everythings ready to go. If you want to expand the system, you just add another room, and another and another scalability is fierce! Another strong argument for this solution is information safety. This kind of stand alone-system is not online, which makes it more difficult to hack. If attack-ing the system, it has to be done while physically inside the room, as it cannot be done over the Internet.

    auto-connect for allHuman-centric lighting is a strong trend, giving users the opportunity to work in a lighting environment that sup-ports alertness and wellbeing. e-Sense Tune is developed for any situation where the person owns the lighting and wants to adapt it to personal prefer-ences and tasks. Its intended for cellular offices, conference rooms or activity areas and can easily be combined with

    With the app for e-Sense Tune and a lighting system that includes the hard- and software required, you have a truly innovative lighting control in your hand, or in your pocket. The graphical interface is designed for ordinary users and very easy to understand even if you dont have a clue about what Kelvin is.

    Are you an Apple fan or do you prefer Android? No matter what, e-Sense Tune comes for both platforms, for phones, tabs or your computer. The same functionality and easy, understandable interface meets you in the application. Choose from four preset scenarios or create one or two of your own. As long as you have the device, the control is always at hand.

    other types of control systems more suitable for large open plan offices. e-Sense Tune is easily operated by each individual with a smartphone app. We have created an intuitive interface thats really simple to handle. Once youve made your settings, the lighting systems will automatically identify you and adapt to your personal preferences as soon as you enter the room. The sys-tem connects via the latest bluetooth standard bluetooth low energy BT SMART and weve also developed a unique solution to make sure no users outside the room can affect the system. The e-Sense Tune application has a function for each user to define two

    different personal lighting scenes. It also incorporates daylight mimicking, where you can choose between two different settings inspired by nature. Both settings start with a lower intensity and a warm colour temperature. At lunchtime, the light peaks in intensity as well as in colour temperature, which until now has been getting cooler. During the after-noon, the intensity is once again lowered and the colour temperature gets a bit warmer. The difference between the two settings is that one is slightly cooler than the other, to match different personal daylight preferences. Of course, the application also has a setting for harvesting daylight, making

    sure that the lighting system optimises energy consumption according to the amount of daylight outside.

    in the occupancy cloud In the near future control systems like e-Sense Tune have great potential, says Daniel. From a hardware perspective, they have the possibility to harvest information on, for example occupancy or default set-tings, and pass it on. Though, this requires a gateway and proper settings.

    The evolution of retailWe have not always shopped the way we do today and retail brands have not always looked the way they do right now. At Fagerhult we carefully monitor trans-formations to ensure we can deliver the best suitable and innovative lighting solu-tions when the retail landscape evolves.text katarina morn styf | photo istock photo, elin nilsson, rjan henriksoon

    At Fagerhult we like to look forward, but let us take a moment of retrospection to reflect on how the retail landscape has evolved over time. In-line with the industrial revolu-tion that accelerated the economy a consumer society emerged. This urba-nised social group, sharing a culture of consumption and changing fashion, were the catalyst the retail revolution. Shops were starting to pop up and those in a privileged position could shop till they dropped. Purchases happened over the counter where personal meeting and relationships were key when get-ting loyal customers and sales. what is in the future?Looking forward a few decades you could say that such experiences and services are as important now as then. Still the personal meeting, expertise and touch-and-feel possibilities are what differentiate retail brands from e-commerce. When bricks and mortar retail needs to create added value for the digital natives of the Generation I, they are transforming their brands into community hubs. These not only fuse commodities, education, cultures, art

    and design but also bring digital into a physical experience. Do not be surprised if high-tech 3D body scanners appear, calculating your exact measurements. So no more jeans fitting agony at least not because of size doubts. Also, keep checking your smartphone when shopping. We will be seeing increased personal messaging

    and offers appearing on your phone when entering a certain shop or passing certain aisles of products. the need for changeRetailers that can adapt and innovate in the face of changes will be in a better position to have a long-term engaging brand. The harsh truth is that the

This is why we increasingly understand that new approaches of thinking, doing, being and producing are needed if our brands are to last and consumers are to be kept happy and engaged. Successful long-lived retail brands such as Macys, Bloomingdales, Sears and Abercrombie & Fitch all originated between 18581892.

For instance, our Marathon Tuneable, a LED spotlight that can tune white light from 2700 K up to 6500 K. This mean that we can use the same luminaire in the whole shop, but have a light that enhances different atmospheres and merchandise. A ligh-ting kept relevant in changing times.

  • the science of shopping

    23

    All retailers are interested in increasing sales, using advanced and detailed procedures in terms of marketing and displays techniques to influence pur-chase decisions and light is one of the key factors. Research suggests that more than 65 percent of buying decisions are made in the physical store. All decisions are made consciously but the products and brands in a shop must pass our non-conscious filter to pop up as a viable choice. This amplifies the importance of the retailer to set the stage since a lot of valuable decisions are made on site. Jens Nordflt, PhD in store mar-keting, is dedicated to research and education at the Stockholm School of Economics and at the ICA, one of the Nordic regions leading retail companies. We know that the store experi-ence affects the consumer significantly. Many customers allow themselves to be influenced of what to buy, but also what they should think about a products price and quality. In fact, it is impossible to consider a product without being influenced by the perceptual system. And the perception is mainly affected by visual impression, Jens explains. There are many factors that affect the decisions made in a shop; the prod-uct assortment, the brand, the pricing, how the merchandise is positioned and displayed both in the shop and on the shelves. Research has shown that the shop atmosphere is central; defined by the colours, lighting, scent, sound, design, size and shape. Correlations

    between feelings such as joy and excite-ment affect not only the time spent in the shop but also the share of purchases made.

    the impact of lightAs a large percentage of the purchase decisions are made in the shop, the atmosphere is an decisive factor as well as colours used. We believe that the lighting is an important element not only setting an atmosphere but also enhancing and signifying colours of the merchandise. Furthermore the light itself can enhance or generate colours by using Tunable White or RGB. There are a couple of experiments that have tested the effects of lighting, which is often treated as only one of many elements in the store. To summarise, the research studies show that warm colours draw more attention but conversely cool colours are more appreciated. These findings are something we at Fagerhult have incorporated in the way we plan light. We have examples where we have illuminated displays positioned next to the walls with blue LED strips casting blue light in the whole shop and using warmer light levels on the actual merchandise. Then we achieve a cool, encouraging atmosphere but also draw attention towards the products. This atmosphere can also be achieved with Tunable White that gives even greater flexibility for the retailer. Light has been proven to significant-ly affect two human areas: vision and

    sense of excitement. Lighting is neces-sary for us as customers to process the relevant information in the shop, but it can also enhance specific products where the retailer wants to boost sales. In that way, a well planned lighting solution can increase sales. The commercial impact of a lighting installation can also relate to how well it correlates with the brand val-ues and the total shop experience. These values can be more difficult to measure in direct sales, but we know a good light-ing solution can reinforce brand value and give the visitor a better experience, even if the actual purchase is later made on-line. Lighting is an effective tool when you deliberately want to take the customer around the shop in a predetermined order, and a perfect way to complement and strengthen the effects of the layout of the store.

    light that sellWe have done tests in shops where we displayed soft drinks bottles with narrow beams and a warm light to bring out the warm colours of the bottles. We com-pared this with the same display using only the general store lighting, which is very common in supermarkets today. The customers paid more attention to the accentuated bottles and the sales of those increased. It all comes down to how our eyes and senses work. Our eyes and senses are always looking and searching for the brightest spot, thats where the information is no light, no information.

    Every city wants to be one but what is it? Opinions on how a smart city should be are as many as the aspirants, though there is an end result which counts for them all. By using modern technologies knitted together, the smart city is a step towards a more sustainable society. The development is driven by urbanisation. In Metropolitan areas the concept is a way to meet the pressures resulting from an increasing population. The EU is an enthusiastic promoter of the movement and is running its own Smart Cities Initiative in order to accelerate the transformation of cities into fossil-free and low-resource communities.

Its extremely important that you dont embark on this kind of project for technologys own sake. A smart city should be created for the benefit of the citizens, to improve their quality of life. For Copenhagen this is also an important step to realise our vision of a C02-neutral city in 2025, says Sren Kvist, spokesperson and Project Manag-er at Copenhagen Solutions Lab, the City of Copenhagens incubator for smart city initiatives. Copenhagen Solutions Lab works cross-departmental with the citys administration, in partnership with local and international companies and

    knowledge institutions. This task group provides a 360 sounding board to evoke and test new ideas, technologies and solutions to create a more liveable city in Copenhagen. The smart city cannot be seen solely as a matter for the community. We need to interact with many different stakeholders: universities, business life and companies related to energy, water, gas, telecom, sanitation and so on The realisation of a smart city needs a holistic approach and weve found this is an easier way to communicate.

    lighting as infrastructureAnd even if the potential is endless, the connected society has to be born according to a plan. Before heading off, experts were hired to identify pos-sibilities and socio-economic effects. Right now, Copenhagen Connecting is entering a new phase. A test area is built for evaluating different solutions and techniques. Were not first to the ball, many of these technologies have been tried in other cities but we need to make sure that theyll work in our Nordic climate and environment, says Sren Kvist. An innovative twist is how Copenhagen is planning to use outdoor lighting as infrastructure for the smart initiative. Street lighting is everywhere and every luminaire is connected with electricity, something thats crucial to get all this tech stuff working. In the coming years 20 000 existing streetlights will also be changed into LEDs. Of course its a good thing for the

    environment as they are very energy efficient. But its interesting how light-ing is also turning into an infrastructure solution, as a vital part when building connectivity, says Sren Kvist. Every LED-module can be connected to the citys IT-system where they can interact with each other. The lighting poles are also excellent for housing sensor equipment for water, wind and pollution as well as for traffic sensors. LED-luminaires also have an important advantage as they are always operating. Theyre never totally switched off, only dimmed to extremely low levels. This means that other equipment will have power supply, regardless of the time of day.

    from traffic to floodingThe ideas are flowing. Traffic is a core subject. For exam-ple, we can use the system to generate data for traffic lights, in order to create green waves for car drivers, cyclists and pedestrians. This means reduced pollu-tion related to red light starts and stops and a safer traffic environment with less accidents. But it also saves valuable time for our citizens. Parking is crucial. If the system can be used to guide drivers directly to a free parking lot, it will save a lot of driving, irritation and CO2, Sren Kvist explains. Sanitation is another area that we are looking into. With the help of intelligent trashbins we can keep the city clean and plan our routes in a more efficient way. Recently weve had some problems with heavy rains and flooding and this system could provide us with

    the information to guide our efforts Some of the ideas are already up and running as the municipality of Copenhagen is gifted with an enterpris-ing traffic department. For instance, one has developed a green wave applica-tion helping commercial traffic to avoid red lights. Copenhagen is known for its well-developed cycling infrastructure and some routes are paved with LEDs shifting between red and green light. This helps the cyclists to keep the right speed and avoid unnecessary stops.

    a sharing societySo, what can the lighting industry do to keep up the pace? Actually, I think the industry is doing a lot. After many years focusing solely on energy efficiency, produc-ers have started to develop products adapted to network technology. I think

    it is important to continue on this path, focusing on connectivity and Internet of Things. For us it is also vital that developers within the lighting industry choose to work with open technology, says Sren Kvist. Open technology means flexibility and the possibility to share information for the greater good. Our vision is to generate open data that can be shared with local entrepre-neurs and companies with business ideas that contribute to the smart city and peoples wellbeing. Of course, we carefully consider integrity issues at all times and living in a big data era we have to design all smart city solutions with citizens privacy rights in mind.

    Lighting control a look into the futureSo, it is finally happening. Lighting control systems are booming with new intuitive and user-friendly applications. Actually, lighting will form the core of our connected working environments, says Daniel Unoson, Product and Application Manager at Fagerhult, looking into his crystal ball to see where we will end up next. text amelie bergman | photo mats andersson

    You know the feeling: The growing frustration when trying to master the remote control in the conference room, while your customers are impatiently watching your every move. Or the defeat of calling the hotel front desk in the middle of the night on how to turn off the **** floor lamp that wont respond to your feverish commands on the control panel. After decades of more or less intricate, non-user-friendly system solutions were finally up for a shift in paradigms. Lighting control systems have become more accessible and easier to install and use. At the same time, demand is growing really fast. There are several different factors behind the development, says Daniel. As sustainability is an increas-ingly important issue in business, companies are searching for a way to minimise energy consumption. In this, lighting control systems are the natural approach. The new connectivity opens up for creative solutions and user-friendly interfaces enhancing the benefits. The Internet of Things phenomena is exponentially growing. Right now about 8 billion units are connected. In 2020 the figure is estimated to between 50100 billion. No one really knows how much or how fast it will grow. But lighting plays a central part in this new Internet of Things infrastructure. As lighting is

    present everywhere, in every building, its a natural connecting point.

    connected lightingUsing data from the lighting system is an interesting topic. The lighting system could connect with ventilation or communication systems in conference rooms. It could also be developed to integrate with the occupancy cloud giving the company information about occupancy, space efficiency and cleaning. The collected occupational data from the lighting con-trol system can be of economic value. Right now, we see a lot of different ideas developing on the market. For example, different providers of vending machines or cleaning services could be willing to pay for information on how to manage their activities in the best way. And as long as it doesnt intrude on person-al integrity and the system is only logging activity, no personal data it shouldnt be a problem.

    simplicity is keyThis also changes the traditional role of the lighting company. Were not just a developer of innovative luminaires. Our knowledge in the field of lighting what light is, the magic within and how it can be con-trolled for the greater good is some-thing that our customers expect us to share in our different control systems.

    In order to make those solutions effective, we have to offer a wide range of systems covering the different needs of different organisations. From advanced, heavily programmed custom-ised solutions with fixed router con-nections, to easy-installed plug & play solutions and everything in between. Its quite obvious that different ways of working needs different approaches to lighting and that a renovation and refurbishment project will have other requirements than a new construction. The trend is obvious. Systems should be easy to install, program and use simplicity is key. The possibility of continuous changes in the set-up is also important. I think that DALI will be the protocol used for controlling light also in the future, but the medium of trans-porting the signals, via wires or wireless, might be of another type. How about using the lighting system for Internet access? Wireless Internet through LiFi seems to be one of the hottest topics right now? Hmm Ive tested LiFi and yes, it works. But it is still very limited, as you have to direct the phones camera at the luminaire at all times. If not, connection is disrupted. The way smartphones are designed today it makes it a bit hard to do the actual surfing. LiFi is an exciting technology but in situations where you have WiFi up and running, LiFi cannot compete.

    Natural light helps us to set our biologi-cal clock and affects our wellbeing. And artificial lighting can be used for the same purpose. The circadian rhythm can be stimulated with light, for example by using higher levels with cooler light until noon and then slowly return to lower levels and warm light in the afternoon. Our preference for colour tempera-ture isnt static, sometimes we want a cold, activating light, others a warm relaxing one. Tunable White is a new technology permitting the user to alter the colour temperature to what we prefer, via the luminaire itself or the complete lighting system. This kind of dynamic lighting can have a profound impact on the personal wellbeing, alert-ness and productivity, and the evolution of LEDs has initiated new research within the area.

    the first in decadesTommy Govn and Thorbjrn Laike, researchers in Light and Lighting at Lund University, have previously conducted two studies to investigate how humans are affected by ambient light. This time, the research team has focused on which colour temperatures that people prefer

    in a laboratory study when using LED lighting. A study of this type has only been made on fluorescent tubes. LED brings the question to the table once again, says Tommy Govn. How do people react to different colours warm and cold light and is there any difference between us? How do we perceive LED light at different level proportions between in the working area and the surroundings within the normal field of view? The study examines the preferred colour temperatures of participants aged 20 to 70 years. The evaluation is holistic and also includes luminance, glare and LED light flicker.

    105 different light scenesDuring the sessions the subjects could select their preferred colour temper-ature at different occasions from 21 individually fixed light scenes, easily controlled from a tablet. The intensity of lighting in the working plane was fixed at one of the seven steps in a scale from 50 1000 lux and the relation between the working area and the surroundings was set to either 5: 1, 2: 1 or 1:1.

    Pozzo and Combilume (opposite page) are some of the luminaires with Tunable White.

    Most noticeably we see a clear difference between women and men. Women prefer a light that is slightly warmer, men prefer a light that is a bit colder, reveals Tommy Govn. Of course, you cannot separate men and women to work in different rooms! But this knowledge can mean a lot when developing new lighting solu-tions with Tunable White in the future. With increased knowledge about the users preferences it is possible to create more accurate solutions and probably to reduce the range in colour temperature in working areas.

    For each scenario, the subjects could choose between colour tempera-tures from warm to cold, from 2700 K to 6500 K. This meant we programmed a total of 105 different variations. Fagerhult has participated in the studies by contributing with develop-ment and programming of the different lighting scenes.

    Things are happening fast on the lighting market, we now see more and more projects with only LED solutions in all segments and applications. New products from Fagerhult are all LED and sales are exploding. Just a few years ago, we could never imagine the fast impact of LED. But we must never forget about the perception of the lighting as LEDs

    are to be handled with care in terms of glare and lighting comfort. We also see more and more prod-ucts with Tunable White, both in retail and commercial applications. In retail mainly for creating different experienc-es in the store. In offices dynamic light can help the biological clock keep time, especially during the dark months, or

    in rooms with limited access to natural light. But light is not only technical, with nicely designed fittings with LEDs and control systems. The Liter of Light pro-ject run by MyShelterFoundation that we present is a truly innovative way to light up peoples lives.

The design concept focused on the needs of the staff and the activities they were undertaking, while paying consideration to the various exposures to daylight throughout the space. Intuitive and easy to understand controls played a central role, optimising the luminaires which included recessed Notor LED, Pleiad G3 and Avion. The net result was a workspace which, when operating at 100 % output, used only 6 W/m2 and in operation uses just under 4 W/m2. The project recently secured a CIBSE building performance award for lighting and a Lighting Design Award for Low Carbon Project of the Year.

It is developed for the retail segment but works well for all type of areas that have the need for change in white colour temper-ature. Marathon Tunable enables you to change colour temperature with the same luminaire. The colour temperature is ranging from 2700 K to 6500 K. Different colour temperatures give different impressions, for example in jewellery shops gold jewellery are preferably illuminated with a warm-er colour temperature and silver jewellery are on the other hand more desirable in a colder light.

    munsterhuis sportscars, hengelo, the netherlandsMunsterhuis Sportscars is a dealer of the prestigious brands Ferrari and Maserati. Because of a new corporate identity from Ferrari/Maserati, the showroom had to be redesigned. The interior concept was created with a strong contemporary look back to the retro feeling. Therefore, we deliberately chose 3000 K as color temperature. A conscious choice is that each car has its own light stage through stretch ceilings that mark the position of the car. To accentuate the architectural lines LED stripes are positioned as effectively as possible, so that all alcoves guarantee an outstanding interior experience. A linear power LED module (Notor LED) has been chosen for the stretch ceilings and walls. All accent spots are Zone Evo recessed with specifically selected 3000 K LED modules and reflectors.

    Annetta KelsoAnnetta has worked for Philips Lighting in the UK and the Netherlands for over 27 years, in a variety of roles, including Product and Marketing management. For the last 15 years she has been active in the communication and market introductions of lamps, drivers and LED systems for European luminaire manufacturers. Other activities include managing the Philips Lighting Technology Training Program, speaking at Lighting conferences about the transforming lighting industry and writing many articles for the Lighting Trade press.

    Annetta; whats happening within the lighting industry right now? In the first 20 years of my career in lighting I used to have some difficulty in describing to my friends what I liked about the the lighting industry and why I remained there. And indeed, if you looked at it as a dispassionate outsider then it did not seem a very compelling industry to work in. All those dreary fluorescent tubes, awful compact fluorescents and ghostly low pressure sodium lamps. Dreadfully slow, extremely conservative, tradi-tional and dull. No-one envied me. But how different the situation is now. The coming of age of LED light sources for general lighting has shaken the whole industry to its core and dragged it in to the cyclical manufacturing patterns of the semi-conductors world. We have become an industry in the midst of a whirlwind of huge change. But also one that is quickly modernizing and reinventing itself, thereby appealing a lot more to todays consumers and triggering wider interest. What has the impact been on the lighting industry? The psychology of a new tech-nology moving in on a 120 year old established, slow and traditional market has been fascinating to observe. I witnessed first-hand the emotions and struggles of the value chain, where huge mental change was taking place, provoking a whole cycle of reactions from denial, anger, scepticism and eventually acceptance. I faced shouting, angry lighting specifiers calling me a liar. I spoke to luminaire manufactur-ers, loudly denying the rapid advent of LEDs, yet proudly claiming 50 % of their turnover to be in LEDs a few years later.

    The Lighting industry is maturing fast, but it is also an industry under severe stress. Lighting manufacturers today are heavily preoccupied with managing and mastering the mass penetration of LEDs, and its many new practical chal-lenges and application learnings. There is hardly ever a dull moment. annetta about oledThere is a lot of discussion and antici-pation about OLED technology, which is attracting large R&D investments and gaining a strong foothold in the display panel market in mobile phones, laptop screens and televisions. What place and role might this technology occupy in the lighting world in the future? OLED is a highly adaptive material that produces a very beautiful, soft, uniform light effect, without distressing glare. Yet compared to LED specifica-tions and price points OLED technology is still some years behind. It would be wrong to see OLED as a competitor or the successor of LED lighting, super-seding it in the future. It has always seemed quite obvious to me that OLED is a parallel technology, co-existing alongside LEDs, targeting very different applications with a distinct set of ben-efits. OLED technology is well suited to automotive lighting and also for ships and planes. It is also ideal for embed-ding in designer, artistic form factors, removing the boundaries of shape and size associated with conventional light-ing. Its transparency, slim dimensions and bendable characteristics make it a very flexible light source, ideal for archi-tectural and embedded applications, either in the home or semi-professional applications. Being able to integrate

    What if the future is not so much about a new lighting technology, as about the way that light is used and the way we interact with it?Annetta Kelso, Senior Marketing Manager LED Systems at Philips

    light, make glass or mirrors glow, or create a sculptured, curved, diffuse pen-dant luminaire takes lighting to whole new levels that cannot be achieved with LEDs. It is a different playing field.

    and laser technologyAnother technology that is increasingly being mentioned when considering successors to LED is laser diodes? There is research emerging and there are early discussions taking place in the market. BMW has been devel-oping laser based headlamps, which extend the visibility to 600 m, which has grabbed the imagination. Laser light appears to be a good light source for applications where the light needs to be transported or guided over long distances, from one central, remote light source. Very similar to fibre optics which Im familiar with from my previous experience as a Product manager. Laser technology is also being trialed in projector and beamer appli-cations, but not yet in general lighting. From the various sources I have come across on lasers and laser diodes, it seems that there are some quite tech-nical challenges still to be overcome as well, in the areas of efficiency, thermal

    stability, colour rendering, uniformity of beam and safety.

    no turning backHow do you see the future of lighting? Nowdays it is unthinkable that we would ever turn back the clock towards the old conventional light sources. It seems to me that LED technology is perfectly capable of providing efficient, high quality, white light, and will build up a formidable pedigree in the foresee-able future. And yet there are already those who are looking ahead and voices speaking out at conferences, debating what might come next. It is an interesting question; are there further major tech-nological changes, imminent or already apparent on the horizon?

    linked to emotionsApart from light itself, Annetta con-tinues, I would look at the future of lighting from another perspective. What if the future is not so much about a new lighting technology, as about the way that light is used and the way we inter-act with it? What if lighting was to fit into to a larger eco-system and become valuable to end users for other reasons

    than just providing illumination? You are talking about connected lighting? Yes, connected lighting is at the centre of all lighting discussions and speculations right now. And, unlike OLEDs and human centric lighting which are familiar terrain, connected lighting is still relatively unknown, undefined and more intangible. Yet it has the power to throw our current lighting world upside down (again) and change the way we experience and interact with light. Lighting is already joining the Internet of Things in the consumer world. Connected light bulbs, such as the Philips Hue system, allow you to control the colours, ambience and intensity of the lights in your home, via your smart phone, when and where you want, at work, or on holiday. But they can also go beyond mere illumina-tion. Via apps the lamps can alert you to other significant events touching your life; football clubs scoring goals, stock prices rising, your husband about to arrive home (!). These are fun and exciting things that brighten up your everyday life. This is lighting linked to emotions.

    OLEDs transparency, slim dimensions and bendable characteristics make it a very flexible light source, ideal for architectural and embedded applications.

    professional lighting connectedBut would this fun element translate to the hard, rational professional lighting market? Not likely! Any form of connected lighting in the professional world will have to be based on rational argumen-tation and the promise of money saving, or money generating activities. It will be about lighting, as a carrier for providing information about the way people are using a building, moving through a street, or shopping mall. Think of intelligent luminaires receiving signals and instructions, sending data and interacting with other systems and databases. It will be about managing lighting assets in a city, sim-plifying maintenance, gathering data to allow for manufacturers to offer service contracts.

    this happens nowWhy should we be so sure that this will happen, and why now? All the market signals are now pointing to viable business cases. The cost per lighting fixture to be connected is predicted to be lower than ever, taking in to account reduced installation time due to quicker, simplified wiring and less commissioning issues. The omnipresent, extensive infra-structure of lighting will make it an ideal carrier for connectivity in the profes-sional and commercial world. We should think in terms of value creation through

    the real estate of lighting opportunity. The value of big data collection and analysis on the behaviour of people is recognised as a business opportunity by companies for more direct targeting of customers. And Lighting is everywhere where people are and is therefore an ideal platform to capture and monitor human centric data. In the Connected Office intelligent lighting systems will not only provide light in a cost effective, efficient manner, but will also interact, via IT systems, with HVAC, blinds and security systems to offer even more savings and flexi-bility. Knowing how a building is used offers potential for reducing square meters per employee and therefore money savings. Similarly in Retail, targeted custom-er interaction can be greatly enhanced by knowing a persons exact location in a store at a particular moment. All these connected lighting services will require software support, maintenance and consultancy support, an excellent opportunity for services and value added selling.

    connected lighting affect productsHow do you think connectivity will affect product development? Connected lighting technology will enable multiple application possibilities and the challenge will be to define the winning propositions and their real benefits. The diversity and complexity

    of options and products will certainly increase. I think we will see a rise in intelligent luminaires, equipped with smart hardware and software compo-nents, in the shape of LED Light engines, lamps, radios and sensors. Future proof, forwards and back-wards compatibility should be key criteria here to facilitate easy upgrades for future applications and solutions unknown today. System solutions should be robust, reliable and intuitive and easy to use. They will also need to address privacy, safety, reliability and system and data security.

    changed value chainWhat other changes do you foresee to make this happen? None of this can be achieved by just maintaining the existing value chains and infrastructures. For lighting to be able to talk to different systems in a building or city, and link in to big data collection points, you need new parties such as IT companies, system integra-tors and software designers to become part of the new eco system. So with the Lighting and IT indus-tries set to entwine, new partnerships will arise around the current value chain, focusing on serving the profes-sional end user. Lighting companies will have to learn the language of system integrators, IT networks and software providers. The end user will be increasingly advised by a new breed

    of specifiers, with new forms of lighting tenders and products specifications. So there are plenty of changes and innovation still to look forward to then? There are still many steps to take along the road to connected lighting sys-tems and many unanswered questions. Much will change and this will not be an easy transition for lighting manufactur-ers. But with all the boundary conditions in place, the rewards could be substan-tial, as a whole new vista of value added service opportunities will open up. We live in exciting lighting times!

    from the fagerhult perspectiveThe lighting industry is in the middle of a paradigm shift, experiencing some radi-cal changes. Whats happening Leif? We are experiencing the LED-fairy tale, for real. After years of discussions, preparations and product development, the technology is mature for commercial success. The market is booming right now. New products find their way to the market immediately, and the surge is intense. Five years back, the major part of our sales were products older than three years, novelties needed quite a long time to establish themselves on the market. Today, new products are driving the whole deal. In February 2015, LED counted for 60 percent of our monthly turnover. That pretty much says it all. What are the challenges in your perspective at Fagerhult? Actually, lighting has changed into another industry. Traditionally, lighting was a manufacturing industry focusing on mechanics and light sources. Today, we work with semiconductors, which basically means that were part of the electronics industry. This brings new demands on competence and skills development, both right now and in the future. As theres a new, more energy and cost efficient LED-version presented every eight month, we also need to have the strength and capacity to upgrade the existing LED range at regular intervals. Not to forget; innovative product devel-opment has to be up and running at all times.

    fagerhult and connectivityWhat about connectivity? Is Fagerhult taking any actions within the field?

    In the story of connectivity, lighting has the opportunity to play a leading role, as it offers an already existing infrastruc-ture indoors as well as outdoors. This infrastructure serves as a central part of the Internet of Things. Though, in my opinion, I think we should be aware that were only at the beginning of a long journey. There are many communicating devices to be linked together and it is a complicated process. At Fagerhult, we see great opportuni-ties and are following development very closely. It is reasonable to believe that lighting will be an asset when collecting data for the cloud, for example data on occupancy and efficiency. Information can be used for strategic decisions concerning facility management and organisational development. From being a provider of lighting solutions, I think lighting companies in the future will also have the role of consultants.

    led is here to staySo, what happens now? From Fagerhults perspective, LED is the obvious technology for the foreseea-ble future. OLED is clearly interesting, but considering efficiency and cost aspects, I see OLED mainly as an alternative for architectural or creative solutions just as Annetta says. For professional lighting, LED is the most commercially viable option. And of course, LED will be further developed for new exciting applications. For exam-ple, I believe LED will be part of several integrated solutions in wall modules or different types of store interior. In times of technical breakthrough and progression, I would also like to add something about the importance of visual comfort very Fagerhult, I know! Leif says with a smile. He continues; But we must not forget about visual comfort. LED light is incredibly intense and therefore it is more important than ever that we take into account the lighting environment. Glare and colour stability over time cannot be overlooked. Lets not throw 70 years of acquired knowledge out the window. It might be a brave new world, but technol-ogy should always serve people.

    Over the last 70 years within the lighting industry various new findings have come our way and we have embraced the change. When we started 1945 there was the light bulb but as the years have passed, new light sources and technologies have emerged, like the LED revolution of last couple of years.text klas andersson | photo fagerhult

    Innovations for better light

    For each new development we have increased our understanding of light, providing the stimulus for new solutions which deliver good, energy efficient, lighting for humans. A lot of the new findings have forced us to learn and re-think what we knew during the years.

    compact fluorescent lampIn mid-eighties there was a new light source on the market, the compact flu-orescent lamp. Suddenly we were able to make energy efficient lighting with smaller dimensions such as downlights and wall luminaires. It was an intensive light source and there was a lot of light that had to be taken care of. This little light source could have a luminance (light intensity) up to 40.000 cd/m2! Basically we had the energy efficiency of a fluorescent tube in a miniature size. The new light source suddenly became an alternative to the traditional bulb in a lot of applications and led to a whole new range of stylish fittings.

    reflector technologyIn the very first Pleiad downlighter that was released in mid-nineties we devel-oped a symmetrical light distribution

    from a horizontally positioned lamp. Why horizontally? We simply wanted to keep the recess depth as low as possible since there often is a lack of space above the suspended ceiling. With a lot of engineering skills we designed a reflector with symmetrical light distribution with excellent cut-off from the horizontally positioned lamp! When others made cut-outs in the reflector for lamp switch we made a toggle solution for that in order to get the most light out of the Pleiad.

    electronic ballastsIn the early nineties we also got the electronic, high frequency ballasts resulting in increased energy efficiency and a flicker-free light! At Fagerhult our big issue was controlling the heat on the ballast since heat kills electronic devices. After some years we introduced our own policy regarding thermal control and stated that we should always have at least a 5 C margin to the stated TC-point on electronics.

    the t5 led to r5-louvreAnother good example of innovation is when the T5 fluorescent lamp entered

    the market in the mid-nineties, making many of the norms of T8 luminaires irrelevant. One aspect was that the T5 tube performed at the best at an ambi-ent temperature of 35 C instead of T8s 25 C. Next thing was to decide what we should do with all light and how we should control it? The luminance in cd/m2 values rose about 50 per cent and compared to the T8 there where issues with glare from the new, highly intense light source. The answer was to design totally new double parabolic louvres that were not only glare-free but also provided higher efficiency to the luminaire. The solution consisted of side and cross reflectors where the cross blades were designed with a sealed top that reflected the light back into the side and top reflectors which minimised the light losses. The curved tops of the cross blades eliminated unwanted reflections on the side reflectors and gave a good mechanical cut off in all directions.

    Loop Light is one of Fagerhults best selling T5-products with more than 300.000 sold over the years.

    To maximise the light output out of the luminaire we also made the cross blades thinner and that itself made the light openings area approximately 4 percent larger, resulting in higher efficiency.

    ledLED revolutionised the lighting land-scape; high light flows ensured superb efficiency and economy, with a lifespan of tens of thousands of hours. From what was previously the domain of decorative accent lighting, LED technology evolved into a practical, general lighting option. To truly embrace the benefits of LED, and to address the demands it posed in issues of glare and heat management, required completely

    new solutions, rather than just changing the light source. The great challenge with LEDs is to keep glare within reasonable levels. It is not unusual that diodes and LED modules have a luminance (light intensity) of over 300.000 cd/m. In con-trast, a standard T5 fluorescent tube has a luminance of 17.000 cd/m. Again, we started from scratch, developing new luminaires specifically for LED, creating viable solutions across the whole spectrum of a lighting project. LEDs greatest advantage is also its greatest challenge. Balancing efficiency with ergonomics. Combining good economy and lighting comfort. With our experience, lighting know-how and innovation we did just that .

  • breakthrough in gerontology?

    We live longer. As the average life expec-tancy increases, we are also increasing our expectations for a long and happy life. Retirement is postponed and people often choose to work into their 70s. Consequently, there are many reasons to do research in the gerontological field. Current and future retirees want to live an active life and want to remain liv-ing in their home environment as long as possible. It is also becoming more common to be cared for in ones own home, says Tommy Govn, researcher in Light and Lighting, who conducted the study with Prof. Thorbjrn Laike at Lund University. The research duo specialise in investigating how people are affected by increased ambient light, with their previous work focusing on students in primary and secondary schools. Now, they are looking into the situations of the elderly. The study is yet not com-plete and will be presented at the 28th

    customised led-lightingThe aim was to explore whether dynamic ambient lighting may have a positive impact on the alertness, wellbeing and health of the elderly. The study was conducted in a nursing home with participants over the age of 80. A specially designed LED-luminaire for increased, glare-free, ambient lighting was designed and installed in the dif-ferent rooms of the nursing home the residents bedroom, the day room and the dining room. Fagerhult contributed in the development of the luminaire and has also been involved in developing control- and measurement equipment as well programming of the different lighting scenes. The study was conducted over one year, investigating the residents feelings regarding light experience, wellbeing, alertness and sleep during the four

    seasons. Other parameters considered were nutrition and medication as well as energy consumption.

    supports circadian rhythm Every one of us is affected by the sea-sons and the availability and absence of light. When getting older, the circadian rhythm is disturbed by various reasons. The lens of the ageing eye leads less light to the retina and elderly who have difficulties moving may not have the opportunity to take advantage of the daylight outdoors. This may disturb

    the circadian rhythm, leading to sleep disorders. Our hope is that the dynamic ambient light can make a difference, explains Tommy Govn. Although no results yet been presented, it looks very promising, he reveals: The test persons subjective expe-rience is that they felt less drowsy and more alert during the days, even in the dark season. The quality of sleep was also better for the experimental group; they tended to wake up less during the night. We have also noted fewer injuries

    due to falls during the test period. An interesting turn is that all subjects have asked to maintain their new lighting If the presented results meet expec-tations, this knowledge may contribute to a new way of lighting the living environments of the elderly. For the individual it means improved quality of life and health. For society, there are possibilities to major savings from less institutionalisation and lower costs for medication or treat-ment of injuries. Its time to enjoy our otium.

    e-Sense Organic can be compared to a school of fish, where every individual continuously makes small decisions in response to its neighbours and environ-ment. Each fish operates independently yet it is part of a flexible system using distributed intelligence to solve com-plex problems easily, without central control. e-Sense Organic is a system that applies natures algorithms in a similar way. This plug & play system is the perfect choice in situations where you want to achieve optimal energy savings without complicated installations or any programming at all. Its very cost effective to install: you just put up the luminaires and thats it, explains Daniel Unoson, Product and Application Man-ager at Fagerhult.

    like a conversationEach luminaire is equipped with a com-municating IR tranceiver. The moment a sensor node detects occupancy, the luminaire responds with a predeter-mined light level. Simultaneously, it communicates with the luminaries in its immediate surroundings, telling that there is something happening. The near-by luminaires react by lighting up on a slightly lower level, and continue to send the message forward. This way, the luminaires creates an occupancy cloud, sharing informa-tion and responding to it as individual fixtures. The premises are always lit to facilitate work and make people feel secure. Its almost like the luminaires are having a conversation. I saw someone

    independent of changes Naturally, e-Sense Organic is equipped with daylight harvesting as well as presence detection features. As it is built on infrared communication, the system wont be affected by layout changes. Walls and function can be changed without any engagement with the lighting. It is flexibility in a nutshell.

    When launched in 1969 Fabian was Swedens maybe even the worlds ever first fitting made of plastic. It was a huge success and sold over 4 million copies. According to the birth certificate, Hkan Fransson is Fabians proud father. At the time of inception Hkan Fransson worked as an in house designer at Fagerhult. With a safe hand and fluent lines he imprinted Fagerhults visual expression during the late sixties. Ive always have had a soft spot for curved, chubby lines, Hkan admits, while walking down memory lane.

    But I really do think that Fabians wild success was a spot-on combination of innovative material and design com-plimented by a very affordable price. Hey, it only took 11 seconds in assembly thats lean production!

    innovation at its bestYoung Fabian had been endowed with a range of fantastic properties, donated by his three fairy godfathers former development manager Bernt-Olof Berntsson, engineer Jrgen Johansson and the late Elis Svensson, head of Fagerhults prototype workshop.

    At the time, Fagerhult was still a large supplier of domestic lighting and the marketing department called for a new wall mounted bedside luminaire with a competitive price tag, as Jrgen Johans-son still a member of Fagerhults development team recalls. Actually, our aim was to force the price all the way to the basement, and in order to do this we had to reinvent ourselves. Our eyes turned towards polypropylene that was quite new to the lighting industry. No one really knew what it was really capable of. But as it turned out,

    Bernt-Olof Berntsson continues, we had a local supplier of this brand new material. The suppliers main products were thermoses with a housing of injec-tion-moulded plastics that came in two different sizes. The housings could easily withstand the warmth from the hot beverages but could it take the heat from a bulb? Trial and error was the only way forward. We slaughtered two thermoses, one of each size, and from the two hous-

    ings Elis created the first prototype, Bernt-Olof remembers. Several prototypes later the devel-opment team had created a seamless, screwless design that could easily be implemented in the production system. Due to the absence of screws, assembly could easy be done with the help of a special fixture. The procedure was clocked at 11 seconds flat. Still, Fabian required heavy invest-ments. I specifically remember one

    meeting when the supplier pointed out that this would require some new, expensive injection tools. But Bertil Svensson, Fagerhults founder and managing director, was in good spirits. We are planning to sell 10 000 units of this fantastic luminaire. Just go ahead!, he said encouraging. No one could have guessed that Fabian actually would sell 4 million copies!, Jrgen Johansson laughs. Fabian was off to a flying start as Swedish department store chain EPA

    placed an initial order for 5.000. The introduction price was set to 19.95 SEK, equivalent to 18.80 today. Fabian was cleverly marketed as an all-round luminaire that did not just belong in the bedroom, but in the living room and the study too. Youll need at least five Fabian at home!, the ads stated. The fact that Fabian was offered in a wide range of colours following the latest interior design trends contributed to its persistent success. Soon, Fagerhult became known as the frontrunner within plastics. This resulted in several iconic luminaires as Cobra and Lucifer, the later designed by the it team in plastics A & E Design,
