An incandescent light bulb also known as an incandescent lamp is an electric light with a wire filament which produces light when current passes through it. Incandescent lighting is cheap to produce but is very inefficient, converting only 5% of the energy into light.

Tip:Incandescent light bulbs have been discontinued from sale above a certain wattage in many regions, as they are not very energy efficient. If you are still using incandescent lighting, it is highly recommended you switch to LED or CFL lighting to save energy and increase the longevity of your light bulbs.
