  • It functions on principle of heating up thin, usually tungsten, wire by the current flowing through it.  It starts to emit light when it reaches high temperature, but it consumes most energy emitting heat.  Because of that LED lights are now used, which are much more efficient and saves power. You can test and compare both types of lights in one of the circuits.
