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.
Arc Light missions continued until the cessation of hostilities by U.S. forces on August 15, 1973. Between June 1965 and August 1973, 126,615 sorties (B-52D/F/G) were flown over Southeast Asia. During those operations, the U.S. Air Force lost 31 B-52s; 18 were lost from hostile fire over North Vietnam and 13 from operational causes. [citation ...
An arclight or arc lamp is a lamp that produces a bright light by generating an electric arc across two electrodes. Arclight , Arc Light or arc light may also refer to: Arts and entertainment
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 ...
A single tower cast light from six carbon arc lamps, illuminating a 1,500-foot (460 m) radius brightly enough to read a watch. [3] In 1993, the city of Austin dismantled the towers and restored every bolt, turnbuckle, and guy-wire as part of a $1.3 million project, the completion of which was celebrated in 1995 with a citywide festival.
1835 James Bowman Lindsay demonstrates a light bulb based electric lighting system to the citizens of Dundee. 1841 Arc-lighting is used as experimental public lighting in Paris. 1853 Ignacy Łukasiewicz invents the modern kerosene lamp. 1856 glassblower Heinrich Geissler confines the electric arc in a Geissler tube.

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.
