A fluorescent lamp or a 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 bulb to glow.
The two most common types of lighting fixtures today are incandescent bulbs and fluorescent lamps. Incandescent bulbs are rather old and outdated while fluorescent lamps are relatively new and is replacing incandescent bulbs in a lot of applications. The biggest difference between the two is in how they produce light.Incandescent bulbs produce light by a heating a metallic filament until it starts to radiate light. On the other hand, fluorescent lamps produce light by exciting a gas and causing it to glow.ome people do prefer the warm light produced by incandescent bulbs, which is more like the light from the sun, compared to the clinical white light produced by fluorescents. Summary: 1. Incandescent bulbs produces light from a heated filament while fluorescent lamps produce light by way of a gas discharge. 2.
