context_page_description: 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 that closely mimics natural sunlight, with applications in movie projectors in theaters, in searchlights, and for specialized uses in industry and research to simulate sunlight, often for product testing.
  Xenon headlamps in automobiles are actually metal-halide lamps, where a xenon arc is only used during start-up to correct the color temperature.
context_section_description: Interest in the xenon discharge was first aroused by P. Schulz in 1944, following his discovery of its near-continuous spectrum and high colour rendering white light. Owing to wartime limitations on the availability of this noble gas, significant progress was not made until John Aldington of the British Siemens lamp company published his research in 1949. This triggered intensive efforts at the German Osram company to further develop the technology as a replacement for carbon arcs in cinema projection. The first successful public projection using xenon light was performed on 30 October 1950, when excerpts from a colour film (Das Schwarzwaldmädel) were shown during the 216th session of the German Cinematographic Society in Berlin. The technology was commercially introduced by German Osram in 1952. First produced in the 2 kW size (XBO2001), these lamps saw wide use in movie projection, where they replaced the older, more labor-intensive (to operate) carbon arc lamps.
