LED (lighting)
The acronym for Light-Emitting Diode, a type of semiconductor diode that produces visible light when powered by an electrical current. LEDs are found in a wide variety of electronics, acting as indicator lights on devices like stereos, DVD players, and computer monitors, or amassed into "light bulbs" for use in work lamps or even street lights. LEDs are growing in poularity as an even "greener" alternative to incandescent and fluorescent lights, because they have a typical lifespan of 50,000 to 100,000 hours, and product a cool, fairly bright light with very little electricity.
