A Light-Emitting-Diode (LED) lamp is a solid-state lamp that uses light-emitting diodes (LED’s) as a light source.
LED light bulbs typically last 50,000 hours, twice as long as fluorescent’s, and are up to twice as efficient. Unlike fluorescent and incandescent bulbs, LED tubes do not get especially hot.
A sampling of LED lamps:
LED lamps are relatively expensive but offer the longest life and greatest energy savings among lamps. The market for LED lamps is expected to explode over the next decade as the price continues to drop.
