Whats energy saving light bulb?
Energy saving bulb ( also called compact fluorescent bulb, energy saving lamp, compact fluorescent light bulb and compact fluorescent lamp) generates their light on the same principle as fluorescent lamps. An electrical charge is passed through mercury vapour between two electrodes. This electrical field causes the vapour to emit invisible UV radiation. Fluorescent material applied to the inside of the glass tube converts the UV radiation into visible light. Different fluorescent materials give the light different colour appearances.
