The electric light bulb produces visible light when an electric current is applied.
Light bulbs are used not only for lighting but also for illuminated signs.
The incandescent bulb was the first type invented. The electric current heats a filament to high temperature. To prevent the filament burning, it was enclosed in a bulb filled with a gas or in which a vacuum had been created. This very inefficient technology is slowly being replaced by two new technologies: compact fluorescents and LEDs. These two systems employ fluorescence and the electroluminescence of semiconductors to produce light much more efficiently.
How to choose
Bulb choice is based on socket type and desired amount of light.
