Answer 2

An L E D light-emitting diode is a two-lead semiconductor light source. It is a p–n junction diode that emits light when activated. When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons.
Benefits Of LED Lighting. LEDs are extremely energy efficient and consume up to 90% less power than incandescent bulbs. ... Also, money and energy issaved in maintenance and replacement costs due to thelong LED lifespan.LEDs have a lifespan of up to 60,000 hours compared to 1,500 hours for incandescent bulbs
