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.
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 [33] [34] It was used commercially beginning in the 1870s for large building and street lighting until it was superseded in the early 20th century by the incandescent light.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.
