WHY LED STREET LIGHT TECHNOLOGY

A light-emitting-diode is a semiconductor diode that emits light when an electric current is applied in the forward direction of the device. The effect is a form of electroluminescence where incoherent and narrow-spectrum light is emitted from the p-n junction in a solid state material. The light characteristics of an LED are a focused narrow band of light. Until recently diffusing the light beam into a large area has been a problem. With current technological advancements the light stream can be focused to any size area in any pattern desired. The extreme low energy consumption is the wonder of the LED. A 100 lumen incandescent lamp will burn 100 Watts per hour, while a 100 lumen LED will burn 17 watts per hour. The 100 Lumen induction lamps will burn 23 watts per hour, making the induction the only real competition for LEDs. The battle boils down to light focus (light pollution) and environmental hazards. The LED can be focused, the induction lamps cannot, and the induction lamps have mercury, the LEDs have nothing harmful to the environment, easing disposal and cutting maintenance costs, yet again.

• Long life span 100,000+ Watt hours;
• Very high energy conversion efficiency of between 80 and 100 Lumens/watt;
• Minimal lumen depreciation (decline light output with age) compared to other lamp types as filament evaporation and depletion is absent;
• “Instant-on” and hot re-strike, unlike Sodium vapors and Metal Halides;
• Ability to focus exact luminous area;
• Focus area and color design help eliminate light pollution;
• CRI (Color Rendering Index) of 80-90;
• CCT (Correlated Color Temperature) available from 2000K to 10,000K;
• No toxic materials used in manufacturing;
• Solid State construction, no moving parts, very rugged;
• Environmentally friendly, uses less energy (76% less than current lamps);
• Environmentally friendly, can be disposed of in landfills.
