Light is not used in light bulbs; light is created in light bulbs. From Edison to the invention of solid state devices, light bulbs were mostly incandescent. They made light by running electricity through a tungsten filament inside a glass bulb with the air removed. The filament got very very hot and emitted light waves (photons). The lack of air (oxygen) preserved the filament from burning up. The efficiency was atrocious, but they made light.
