What is LED???
LED stands for Light Emitting Diode. This technology has until recently been used primarily for Christmas tree lighting and other colourful decorative lighting (outdoor architectural and indoor mood) but is now moving into the mainstream lighting world for offices, shops, industry and homes. LED lighting is devoid of hazardous substances (lead, mercury) like CFLs and consumes less energy than CFLs. LEDs are most suitable for directional lighting uses.
LEDs are generally speaking more efficient than halogens, incandescent, fluorescent and high pressure sodium lighting technologies.
