The future of lighting is LED
Why LED? Solid state technology, cost less to maintain, reduces utilities cost, more efficient than fluorescent or incandescent, environmentally safe, less need to replacement, means less waste, excellent lumen efficacy, excellent thermal efficiency.
What is the LED light definition?
LED stands for; light-emitting-diodes, and first developed by NASA. The LED consists of a chip of semiconducting material doped with impurities to create a p-n junction. As in other diodes, current flows from the p side or anode to the n side or cathode but not in the reverse direction.
