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.
CFL, or compact fluorescent, is simply a mini version of a standard fluorescent light bulb, However, these bulbs fit in standard light sockets without any adaptor. The light appears much like the incandescent light weâre used to, and looks nothing like the harsh lighting we associate with offices or school buildings.
