arc light
Plasma gap illumination
An arc light produces illumination by passing electric current across a gap between two electrodes, creating a bright arc of plasma.
Before incandescent bulbs, arc lights were the primary form of electric lighting, used for streetlamps and industrial applications.
The term persists in specialized contexts like film production, where powerful arc lights provide intense illumination for sets.
