Metal Halide Lamps
Metal halide lamp is a member of the high-intensity discharge (HID) family of lamps, produce high light output for their size, making them a compact, powerful, and efficient light source. By adding rare earth metal salts to the mercury vapor lamp, improved luminous efficacy and light color is obtained.

Metal halide lamps is operating on AC power, arc discharge in mercury and rare metal halide vapor mixture luminous discharge lamps, metal halide lamp is made to add a variety of metal halide high-pressure mercury lamp on the basis of the third generationlight source. Scandium sodium lighting metal halide lamps, metal halide lamps with high luminous efficiency, good color, long life characteristics of the new energy-saving light close to daylight color is widely used in sports stadiums, exhibition centers, large shopping malls indoor lighting, industrial plants, streets and squares, railway stations, docks and other places.

There are two metal halide lamps (referred to as metal halide lamp), a quartz metal halide arc tube blister quartz, the other is a ceramic metal halide arc tube bubble shell is semi-transparent alumina ceramic metal halide lamp is one of the world's best electric light, it has a high light efficiency (65 ~ 140lm / w), long life (5000 ~ 20000h), good color rendering (Ra65 ~ 95 ), compact structure, stable performance characteristics. It combines the advantages of fluorescent lamps, high pressure mercury lamp, high pressure sodium lamp, to overcome the defects of these lights, metal halide lamp brings together the main advantages of the gas-discharge light source. Especially high luminous efficiency, long life, light color of the three major advantages. Metal halide development soon use more widely.
