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.
CFLs have two main components: a magnetic or electronic ballast and a gas-filled tube (also called bulb or burner). Replacement of magnetic ballasts with electronic ballasts has removed most of the flickering and slow starting traditionally associated with fluorescent lighting, and has allowed the development of smaller lamps directly ...
Other sizes with a data sheet in IEC 60064 are A50, A55, A67, A68, A71, A75, and A80. Another common A-series light bulb type is the A15 bulb which is commonly used in the US for appliances and ceiling fans. The A15 bulb is 15 ⁄ 8 in (1 + 7 ⁄ 8 in; 48 mm) wide at its widest point and 3.39 inches tall.
Incandescent light bulbs consist of an air-tight glass enclosure (the envelope, or bulb) with a filament of tungsten wire inside the bulb, through which an electric current is passed. Contact wires and a base with two (or more) conductors provide electrical connections to the filament.
ISO 5775 is an international standard for labeling the size of bicycle tires and rims.The system used was originally developed by the European Tyre and Rim Technical Organisation (ETRTO).
Diagram of a high-pressure sodium lamp A high-pressure sodium lamp, Philips Master SDW-T 100W. Various types of chemistry are used in the arc tubes of HID lamps, depending on the desired characteristics of light intensity, correlated color temperature, color rendering index (CRI), energy efficiency, and lifespan.
