LED light panel is made from LED(Light Emitting Diode) is made from semiconducting materials which makes it efficiency very high as compare to traditional sources of light like bulb, lamp which uses tungsten, mercury etc. They can operate continuously for thousands of hours with negligible heat emission. Efficiency is said to be around 80% while fluorescent or mercury tube or tungsten able to give only 20% efficiency because of more heat emission. More efficiency of LED panel lights is mainly because of its less loss of energy in the form of heat. This property resulted in saving electrical energy. It gives an inspiration of increasing the use of these lights at public places like at bus terminals, highway lanes etc.
