In electric discharge lamps, light is produced by the passage of an electric current through a vapor or gas rather than through a tungsten wire as in incandescent lamps. The light production by discharge sources is more efficient than the electric heating method used in filament lamps. Discharge lamps used in architectural lighting are more efficient and have a longer life.
This interactive online course will introduce you to the functionality of fluorescent lamps as well as the differences and uses of mercury vapor, high-pressure sodium, and metal halide lamps. We will cover the potential drawbacks of low-pressure sodium lamps and discuss how the selection of phosphors affects lamp color.
