Electricity and light are both forms of energy so to convert one to the other needs a device which for producing light is called a light bulb. In one type of bulb electric current flows through a thin metal filament, heating it to 2000 degrees C so that it becomes white hot and emits light.
It also emits a lot of wasteful heat, so there are better forms of bulb.
