New lighting concept NARVA DT-T8 LED tubes in Brand-Erbisdorf primary school

NARVA LED retrofit tubes are a professional high-quality replacement for fluorescent lamps. These tubes are designed for temperatures ranging between -20 and +40°C, and extend far beyond ambient lighting in application due to their excellent luminous flux values.

Brand-Erbisdorf primary school for general education has the following mission statement: Learning together – with heart and mindThe school’s aim is to teach children a self-assured, socially aware and independent approach to life. The school has 325 children in 14 classes from grades 1 to 4.

The Town of Brand-Erbisdorf together with the school and NARVA planned new lighting concept as part of a regional Saxon energy management initiative. DT-T8 Retrofit LED tubes were selected to save energy and improve lighting conditions in the classrooms and common rooms.

The new DT-T8 Retrofit tubes were installed in classrooms, school cabinets and common rooms. Most of the work takes place in the classrooms, with desks and chairs arranged according to the type of work. The aim was to plan the lighting for any furniture arrangement.

Proper light distribution and even lighting intensity prevent glare, making any type of visual work easier, especially enabling a clear view of the board in front of the class.

The DT-T8 Retrofit tubes feature especially even light emissions and excellent luminous flux values; their high switching capability makes them very robust, and they are also compact and impact-resistant due to the polycarbonate material used.

Energy savings and up to three times the life time of conventional fluorescent lamps make these LED tubes an attractive lighting alternative.

The old lamps in the corridors of the school were also replaced by new LED lamps.

Before the upgrade:The corridors in the school were dark and poorly illuminated.

After the upgrade:The corridors are bright and illuminated.The new light colour 840 was used here.
