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 .
[1] By 1893, New York City had 1,535 electric arc street lights. [1] In New Orleans, arc lamps were used for street lighting starting in 1881. In 1882, the New Orleans Brush Lighting Company installed one hundred 2,000-candlepower arc lamps along five miles of wharf and riverfront; by 1885, New Orleans had 655 arc lights. [1]
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. 1867 Edmond Becquerel demonstrates the first fluorescent lamp. [5] 1874 Alexander Lodygin patents an incandescent light bulb.
Yablochkov’s major invention was the first model of an arc lamp that eliminated the mechanical complexity of competing lights that required a regulator to manage the voltaic arc. He went to Paris the same year where he built an industrial sample of the "electric candle" ( French patent № 112024, 1876).
U.S. patent 335,787 - Electric arc lamp - 1886 February 9 - Arc lamp's automatic fail switch when arc possesses abnormal behavior; Automatic reactivation. U.S. patent 336,961 - Regulator for dynamo electric machines - 1886 March 2 - Two main brushes connected to helices coil ends; Intermediate point branch shunt connection for third brush.
In December 1880, Brush Electric Company set up a central station to supply a 2-mile (3.2 km) length of Broadway with arc lighting. By the end of 1881, New York, Boston, Philadelphia, Baltimore, Montreal, Buffalo, San Francisco, Cleveland and other cities had Brush arc lamp systems, producing public light well into the 20th century.

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.
