arc lamp
An electric light in which a current produces light when an arc traverses the gap between two incandescent electrodes in a container filled with a gas, such as xenon. The two electrodes are usually made of carbon and are eventually vaporized by the heat they generate. Arc lamps are used to produce intense light (as in spotlights) and to produce heat for welding.
