An arc lamp or arc light is a lamp that produces light by an electric arc (also called a voltaic arc). The carbon arc light, which consists of an arc between carbon electrodes in air, invented by Humphry Davy in the first decade of the 1800s, was the first practical electric light.
A xenon arc lamp is a highly specialized type of gas discharge lamp, an electric light that produces light by passing electricity through ionized xenon gas at high pressure. It produces a bright white light to simulate sunlight , with applications in movie projectors in theaters , in searchlights , and for specialized uses in industry and research.
An electric arc between two nails. An electric arc (or arc discharge) is an electrical breakdown of a gas that produces a prolonged electrical discharge. The current through a normally nonconductive medium such as air produces a plasma, which may produce visible light. An arc discharge is initiated either by thermionic emission or by field ...
Different metals emit light at specific wavelengths when energized, and this characteristic determines the lamp's color output. Gas Discharge Process: The lamp's operation involves creating an electric arc across the electrodes within the arc tube. This arc generates intense heat and excites the gases and metal additives within the tube.
The United States Air Force (USAF) Strategic Air Command (SAC) B-52D Stratofortress (serial number 55-0103) of the 4252d Strategic Wing had a full bomb load and broke up and caught fire after the aircraft aborted takeoff at Kadena Air Base while it was conducting an Operation Arc Light bombing mission to South Vietnam during the Vietnam War.

The heat generated by the arc and electrodes then ionizes the mercury and metal halides into a plasma, which produces an increasingly brighter white light as the temperature and pressure increases to operating conditions. The arc-tube operates at anywhere from 5–50 atm or more [8] (70–700 psi or 500–5000 kPa) and 1000–3000 °C. [9]
