Germicidal lamps have designations beginning with G (meaning 'Germicidal'), rather than F, for example G30T8 for a 30-watt, 1-inch (2.5 cm) diameter, 36-inch (91 cm) long germicidal lamp (as opposed to an F30T8, which would be the fluorescent lamp of the same size and rating).

The most common that we see is a fluorescent bent T8 with six-inch leg spacing. Fluorescent Lamps – Definition, Working & Application. Fluorescent bent lamps. Linear fluorescent bulbs come in a wide variety of lengths, diameters, wattages, and color temperatures. Fluorescent Lamp Guide lamp reference August 2014 4' fluorescent MANUFACTURER CCT (K) CRI CATALOG # INITIAL LUMENS RATED AVG. We provide a table of Definitions of Common Lamp (Light Bulb) Abbreviations & bulb Types and we explain the CRI scale for lighting and we discuss the color temperature of different types of light bulbs or lamps.

fluorescent lamp noun A lamp in which light is produced largely by fluorescence; especially a tubular electric-discharge lamp containing mercury vapour, ultraviolet radiation from which causes the fluorescence of a coating of phosphor on the inside of the tube.

The light derives its name from the fact that it is a tubular fluorescent lamp that measures ⅝ of an inch in diameter. The T5 fluorescent lamp is a common grow light used to cultivate cannabis. If you are doing work that requires accurate color rendering as well as bright illumination for detail, look for a light bulb with a color temperature close to 5000K and a CRI of 90 or above. Examples of common universal waste electric lamps include, but are not limited to, fluorescent, high intensity discharge, neon, mercury vapor, high pressure sodium, and metal halide lamps. Typically, the tubes are arranged in a panel so that they are located parallel to each other. ballast - A device required by electric-discharge light sources such as fluorescent or HID lamps to regulate voltage and current supplied to the lamp during start and throughout operation. Determining the tube size of the fluorescent light will help you decide which tube lighting is a suitable replacement. Fluorescent bent lamps come in a few different options. Different manufacturers do it differently. Light bulb type codes, abbreviations, features: Here we define the different types of lamps or bulbs used in lighting fixtures. The starter switch used is a typical bulb consisting of two electrodes such that an electric arc is formed between them as current flows through the bulb. When you are trying to replace fluorescent lighting, whether, with LEDs or another tube, you will need to understand the difference between tube light sizes.. As you would expect, the tube is bent in a U-shape. There is no hard and fast standard. In general, though, you’ll see an “F” which means (duh) fluorescent.
