The design was initiated by the U.S. EPA and the Lighting Research Center in 2004, in order to facilitate the deployment of compact fluorescent light bulbs with replaceable ballasts. [ 1 ] The GU24 fitting is compliant with a 2008 ruling by the California Energy Commission under Title 24 ( California Building Standards Code ) to require high ...
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 ...
Fluorescent lamps in various embodiments. Since their introduction as a commercial product in 1939, many different types of fluorescent lamp have been introduced. Systematic nomenclature identifies mass-market lamps as to overall shape, power rating, length, color, and other electrical and illuminating characteristics.
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 ...
A 3-way lamp, also known as a tri-light, is a lamp that uses a 3-way light bulb to produce three levels of light in a low-medium-high configuration. A 3-way lamp requires a 3-way bulb and socket, and a 3-way switch. In 3-way incandescent light bulbs, each of the filaments operates at full voltage. Lamp bulbs with dual carbon filaments were ...

The most commonly used A-series light bulb type is an A60 bulb [7] (or its inch-based equivalent, the A19 bulb [2] [4]), which is 60 mm (19 ⁄ 8 in or 2 + 3 ⁄ 8 in) wide at its widest point [3] and approximately 110 mm (4 + 3 ⁄ 8 in) in length. [8] Other sizes with a data sheet in IEC 60064 are A50, A55, A67, A68, A71, A75, and A80.
