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 .
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.
[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]
Yablochkov candles were superior to Lontin-Serrin regulator arc lights that each required a separate Gramme generator. Beginning in 1880, the Paris Hippodrome's 20 Serrin lights powered by 20 generators were replaced by 68 additional Yablochkov candles, based on two years of positive experience with 60 candles powered by just three generators.

Invented by Humphry Davy around 1805, the carbon arc was the first practical electric light. [33] [34] It was used commercially beginning in the 1870s for large building and street lighting until it was superseded in the early 20th century by the incandescent light. [33] Carbon arc lamps operate at high power and produce high intensity white light.
Early arc lights were extremely bright and the high voltages presented a sparking/fire hazard, making them too dangerous to use indoors. [17] In 1878 inventor Thomas Edison saw a market for a system that could bring electric lighting directly into a customer's business or home, a niche not served by arc lighting systems. [18]
The arc furnace provides the high temperature required to drive the reaction. [2] Manufacture of calcium carbide was an important part of the industrial revolution in chemistry, and was made possible in the United States as a result of massive amounts of inexpensive hydroelectric power produced at Niagara Falls before the turn of the twentieth ...
In his trials to power more sets of candles with different light flux and in order to obtain different voltages, Yablochkov invented the first transformers. [ 3 ] As any other carbon arc lamps, Yablochkov candles have a very bright light that can be used for lighting large lengths of streets or large interiors such as factories and train ...
