WebIt is the use of this small amount of mercury that allows any fluorescent lamp to produce visible illumination at much higher efficiency levels than incandescent lighting. Typical … 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. A fluorescent lamp converts electrical energy into useful light much more efficiently than an i…
