LED Lighting

Currently white LEDs are expensive to produce but the price will drop as sales increase, manufacturing processes get more efficient, and the economies of scale comes into play.

LEDs promise efficiency that will be much greater than standard incandescent light bulbs because they can be optimized to give off much less heat. Standard light bulbs are hot to the touch and give off a lot of energy in the form of infrared radiation. Replacing incandescent bulbs with white LEDs will reduce the energy consumption of the lights which in turn will reduce air-conditioning costs since LED lights do not give off excess heat.

LEDs have, until recently, been red or amber in colour but recent breakthroughs has added blue, green, and white colours to their spectrum. This development of the white LED means that it is now possible to replace standard white light bulbs with LEDs.

The Light Emitting Diode (LED) is a small low powered completely cool light source. Currently they are mainly used in computers for blinking lights on circuit boards and other displays.
