LED or Light Emitting Diodes, produce the longest-lasting, most energy-efficient lighting available today. A semiconductor rich in electrons and a semiconductor rich in holes are used to create an LED. Passing a current through the junction of these two materials combines the electrons with the holes and produces photons, which is the light that you see.
LED products have recently become a main source of lighting due to its efficiency and many believe it is a 'new' technology. However, LED technology was actually invented in the 1960s and used for as indication lights on devices. With the recent development of white diodes this has brought it into the public eye as a replacement for other white light sources.
LED lights use up to 90% less energy than traditional bulbs, and for businesses that run their lights 24/7 it can mean huge savings. The math is simple: the money they save on energy costs pays for the new LED lamps in a very short time, and after the initial investment is paid off they can add the savings to the bottom line.
