Light Emitting Diodes (LEDs) are semi conductive devices that convert electrical energy into a discrete color of light: red, green, or blue. White LEDs are also available, though these are actually blue LEDs equipped with special phosphors. LEDs themselves are not new, but only recently have they become bright enough and economical enough for everyday lighting uses.

LEDs are a the world's most advanced illumination technology, delivering beautiful light while consuming a fraction of the energy and lasting up to 20 times longer compared with conventional lighting. As such, they are rapidly replacing traditional incandescent & fluorescent sources of light in a number of applications.
