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.
