An LED (light emitting diode) is a semi-conductor

device or chip that produces light when an electrical

current is applied.

LED Lights contain no mercury or other toxins

and emit no harmful UV rays and less CO2 than

standard incandescent bulbs. LED's are a practical

replacement for halogen or standard lights as they have

a lower energy consumption, longer lifetime, improved

brightness, smaller size, faster switching, and greater

durability and reliability.

Until recently LED's have only been used for display

type indicators in electrical devices such as TV's,

calculators and clocks or as decorative lighting, as high

brightness could not be achieved. Advancements in

technology in recent years have opened up LED's to be

used in a wide range of applications in commercial,

industrial and domestic lighting.
