The Centennial Light was originally a 60-watt bulb, but has since dimmed significantly and is now as bright as a 4-watt bulb. [7] [8] [9] The hand-blown, carbon-filament common light bulb was invented by Adolphe Chaillet, a French engineer who filed a patent for this socket technology. [10]
The lights consist of one or more incandescent bulbs or one or more clusters of high-intensity light-emitting diodes (LED). The emergency lighting heads have usually been either incandescent PAR 36 sealed beams or wedge base lamps, but LED illumination is increasingly common.
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 .
As of 2011, incandescent lighting was the most common type used in homes, delivering about 85% of household illumination. [2] To produce light, incandescent light bulbs convert electricity to heat, heating a filament to the point where it glows; a portion of the heat is thus converted to light.
The suffix after the G indicates the pin spread; the G dates to the use of Glass for the original bulbs. GU usually also indicates that the lamp provides a mechanism for physical support by the luminaire: in some cases, each pin has a short section of larger diameter at the end (sometimes described as a "peg" rather than a "pin" [2]); the socket allows the bulb to lock into place by twisting ...

Ceiling fan – may sometimes have a light, often referred to as a light kit mounted to it. Ceiling fans with built-in lights may eliminate the need for separate overhead light fixtures in a room, and light kits can also replace any ceiling-mounted light fixtures that were displaced by the installation of the ceiling fan.
