arc-lamp

Plasma-gap light source

An arc-lamp produces light by passing an electric current across a gap between two electrodes, creating a brilliant arc of plasma.

Before incandescent bulbs, arc-lamps lit streets and large spaces.

The intense, slightly harsh light still appears in film projectors, searchlights, and industrial applications.

Also spelled arc lamp.
