Description:History[ edit ] Before the introduction of LED lamps, three types of lamps were used for the bulk of general white lighting: Incandescent lights , which produce light with a glowing filament heated by electric current. They are being phased out of general lighting applications. Incandescent lamps produce a continuous black body spectrum of light similar to sunlight, and so produce high Color rendering index CRI. Fluorescent lamps , which produce ultraviolet light by a glow discharge between two electrodes in a low pressure tube of mercury vapor, which is converted to visible light by a fluorescent coating on the inside of the tube.
