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 [ 1 ] [ 2 ] It was widely used starting in the 1870s for street and large building lighting until it was superseded by the incandescent light in the early 20th ...

Sir Humphry Davy, 1st Baronet, FRS, MRIA, FGS (17 December 1778 – 29 May 1829) was a British chemist and inventor who invented the Davy lamp and a very early form of arc lamp.
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 [33] [34] It was used commercially beginning in the 1870s for large building and street lighting until it was superseded in the early 20th century by the incandescent light.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.
1809 – Humphry Davy first publicly demonstrates the electric arc light. 1811 – François Jean Dominique Arago discovers that some quartz crystals continuously rotate the electric vector of light 1814 – Joseph von Fraunhofer discovered and studied the dark absorption lines in the spectrum of the sun now known as Fraunhofer lines
Yablochkov's demonstration of his brilliant arc lights at the 1878 Paris Exposition along the Avenue de l'Opéra triggered a steep sell off of gas utility stocks. Sir Humphry Davy invented the carbon arc lamp in 1802 upon discovering that electricity could produce a light arc with carbon electrodes. However, it was not used to any great extent ...
