Fluorescent Light Bulb
This light bulb produces light when an electric arc passes between cathodes to excite mercury and other gases, making a radiant energy. After, it is converted to visible light by a phosphor coating. Some types of fluorescent light bulbs are compact fluorescent lamps(CFL), Linear fluorescent light, and more. It is also available in a wide spectrum of different colours. The fluorescent tube is by far the most common form of lighting. Fluorescent light bulbs are usually most commonly used for the lighting of schools, office buildings, and businesses. Fluorescent lamps contain small quantities of mercury, an essential component, but are far more energy efficient than incandescent lights. In fact,
fluorescent light bulbs use 25%-35% of the energy of incandescent light bulbs to provide a similar amount of light, and are about 2 to 4 times as efficient as incandescent lamps at producing light at the wavelengths that are useful to humans. It also lasts up to ten to twenty times longer as well. However though, this bulb uses 1/5- 1/3 as much electricity as incandescents with comparable lumen ratings. CFLs also release about 80% of their energy as heat.
