Introduction to LED Lights
Your environment friendly, reliable lighting partner
What are LEDS?
• LEDs (light–emitting diodes), are semiconductor devices that produce visible light when an electrical current is passed through them.
• Solid State Lighting (SSL), organic light–emitting diodes (OLEDs) and light–emitting polymers (LEPs) are different types of LEDs

Bulbs and Tubes
How is LED lighting different than other light sources, such as incandescent and CFL?
• LED lighting differs from incandescent and compact fluorescent lighting in several ways. When designed well, LED lighting can be more efficient, durable, versatile and longer lasting.
• LED lighting products use light emitting diodes to produce light very efficiently. An electrical current passed through semiconductor material illuminates the tiny light sources we call LEDs. The heat produced is absorbed into a heat sink.

• Common LED colors include amber, red, green, and blue. There is actually no such thing as a “white” LED.
• To get white light the kind we use for lighting our homes and offices, different color LEDs are mixed or covered with a phosphor material that converts the color of the light.
• The phosphor is the yellow material you can see on some LED products. Colored LEDs are widely used as signal lights and indicator lights, like the power button on a computer.

Garden lights
Solar Garden Lights
Benefits of LED Lighting
Energy EfficientA standard 50W halogen lamp turns 90% of electricity used into heat with only 10% into light. The benefit of LED Lights are that they use only 15% of the energy a standard halogen uses, provide up to 85% of the light output and create less heat making them so cool to touch

Solar Street Lights
Benefits of LED Lighting
Long Life SpanLED Lights have the benefit of a super long life span of up to 80,000 hours which means you can cut maintenance costs as the lamps last up to 8-10 times longer than standard halogen lamps making them an ideal replacement.

Bay Lights
Benefits of LED Lighting
Improved DurabilityLED's have no filaments so can withstand a greater intensity of vibration and shock than standard lights making them durable with less risk of breaking and need to replace.Compact SizeLED Light bulbs can be as small as 2mm making them ideal for fitting into hard to reach and compact areas.

Flood lights
Street Lights
Benefits of LED Lighting
Fast SwitchingLED Lights will start at full brightness, instantly, every time, therefore there is no need for backup lighting. LED Lights are a benefit because they switch on and off instantly making them ideal for flashing signs, traffic signaling and automotive lights, compared to standard compact fluorescent lights which fade in and out or flicker. ColorLED lights are offered in a variety of base colors such as Red, Green, Blue and Amber. Because traditional incandescent light bulbs use filters to produce colors, they are extremely inefficient. LEDS can be blended together to produce millions of color options.

Out door Lights
Benefits of LED Lighting
SafetyMost LED lights operate at low voltage so are cool to touch and much safer to handle during installation and maintenance and can be exposed to rain, snow and dust.
Environmentally FriendlyThe benefit of LED Lights is that they are an eco-friendly form of lighting as they do not contain mercury or other harmful gasses or emit any harmful UV rays. For example, a 13w LED light emits 68% less CO2 than a standard 40w incandescent bulb running 10 hours per day.
