Gas-discharge lamps are a family of artificial light sources that generate light by sending an electric discharge through an ionized gas, a plasma. Typically, such lamps use a noble gas ( argon , neon , krypton , and xenon ) or a mixture of these gases.
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.
HID lamps produce different colors of light primarily through the use of various metal additives in the lamp's arc tube and the physics of the gas discharge process. [11] Metal Additives: HID lamps contain an arc tube filled with a mixture of gases, including a noble gas (like xenon). These metal additives are crucial for producing different ...

Xenon short-arc lamp Space Shuttle Atlantis bathed in xenon lights Xenon gas discharge tube. Xenon is used in light-emitting devices called xenon flash lamps, used in photographic flashes and stroboscopic lamps; [21] to excite the active medium in lasers which then generate coherent light; [141] and, occasionally, in bactericidal lamps. [142]
Like other gas-discharge lamps such as the very-similar mercury-vapor lamps, metal-halide lamps produce light by ionizing a mixture of gases in an electric arc.In a metal-halide lamp, the compact arc tube contains a mixture of argon or xenon, mercury, and a variety of metal halides, such as sodium iodide and scandium iodide. [7]
Gas-filled tubes exploit phenomena related to electric discharge in gases, and operate by ionizing the gas with an applied voltage sufficient to cause electrical conduction by the underlying phenomena of the Townsend discharge. A gas-discharge lamp is an electric light using a gas-filled tube; these include fluorescent lamps, metal-halide lamps ...
Geissler tubes were the first gas discharge tubes, and have had a large impact on the development of many instruments and devices which depend on electric discharge through gases. [ 1 ] : 67 One of the most significant consequences of Geissler tube technology was the discovery of the electron and the invention of electronic vacuum tubes .
