Fluorescent lighting is a highly versatile type of lighting that you most likely encounter at the office, school, or grocery store. It's known for energy efficiency compared to incandescent and halogen light bulbs, and a lower price compared to LEDs. There are several different types of fluorescent lighting including linear fluorescent tubes . Fluorescent lamp A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. An electric current in the gas excites mercury vapor, which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the lamp to glow.It is cheaper than other lights. The Ballast is quite expensive, but it lasts for long. We have to change the glass tube of the light which is around 60% cheaper than other lights. The light from a Fluorescent bulb does not generate heat as much as an incandescent lamp generates. LED Light GuidesT4 tubes are the smallest of the fluorescent bulb sizes, at only 4 eighths of an inch (0.5 in). Their size is what makes T4 lights popular for under cabinet lighting purposes and accent lighting for displays or a staircase. There is no industry standard for the length or wattage of T4 tube lights. They can range anywhere from 6 watts to 30 . Animation shows the circuit of the first kind of fluorescent lamp called the preheat. See how the ballast and starting switch work to strike an arc in the la.
