Metal Halide Lamp
A lamp that produces light as a result of an electrical discharge, generated between two electrodes, in a high-pressure mercury vapor with metal halide additives that is contained in a transparent bulb.
Metal Halide Gas Discharge Lamps
Metal halide lamps are high-pressure mercury gas discharge lamps that contain metal halides in addition to the mercury [2, 3]. In the heated discharge tube, the metals of the halides take part in the discharge process and radiate their own spectrum. Compared with high-pressure mercury lamps, both color properties and efficacy are considerably improved. Thanks to the fact that no fluorescent powder is needed, the small gas discharge tube itself is the light-emitting surface. This small light-emitting surface makes the lamps extremely suitable for use in reflector and floodlight luminaires. Initially, they were solely produced in extremely high lumen packages with relatively large lamp dimensions (about the size of a...
