LED (Light Emitting Diode) is made by using semiconductor of p-n junction diode. These are highly capable and economical lights available in the market. Earlier Fluorescent or halogen or mercury lights uses more energy and also get heated after few hours of operation while these LED Panels can work for hundreds of hours continuously without getting heated. Because of their capability of not heating very much they save energy as energy lost in the form of transfer from electrical energy to heat energy is not there. Due to these capacities they do not emit harmful radiations and are said to be environmentally safe.
