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 [ 1 ] [ 2 ] It was widely used starting in the 1870s for street and large building lighting until it was superseded by the incandescent light in the early 20th ...

    en.wikipedia.org/wiki/Humphry_Davy

    In 1802, Humphry Davy had what was then the most powerful electrical battery in the world at the Royal Institution. With it, Davy created the first incandescent light by passing electric current through a thin strip of platinum, chosen because the metal had an extremely high melting point. It was neither sufficiently bright nor long lasting ...

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 [33] [34] It was used commercially beginning in the 1870s for large building and street lighting until it was superseded in the early 20th century by the incandescent light.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

  8. Incandescent light bulb - Wikipedia

    en.wikipedia.org/wiki/Incandescent_light_bulb

    An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a filament that is heated until it glows. The filament is enclosed in a glass bulb that is either evacuated or filled with inert gas to protect the filament from oxidation. Electric current is supplied to the filament by terminals or wires ...
