L.E.D: stands for ""Light Emitting Diode"", an L.E.D is a small piece of semi conducting material that contains various compounds. When electricity is passed through these semi conductive materials light is emitted in the form of photons. This process is call electro-luminescence.
An L.E.D light can produce the same amount of lumens as an incandescent while using only 25% of the power. Up to 90% of incandescent lights energy is heat created by electrical resistance filament (i.e they are more efficient as heaters than lights).
