What are metal halogenides?

Metal halogenides are gas discharge sources that provide lighting through the passage of an electrical arch through the high -pressure Argon, mercury and metal halogenide mixtures. As in operation as fluorescent and mercury pairs of lamps, metal halogenides are different due to their high light output and different color castings. Due to their relatively small size and high performance, these lamps are widely used to illuminate the stadium, factories, warehouses and outdoor flood lighting. Metal halogenide lamps are available in a relatively wide range of energy evaluation, which usually include variants of 150 to 1200 watts. These lamps require the proper functioning of a special ballast, whose costs are usually justified by a long life and excellent performance. These lamps are suitable for applications where high output is required for their size. Are also useful where specific colors are required because each type has added SP added to their interiorEcific metal salt that produces different light shades. Metal halogenide lamps operate by passing an electric arc with a high voltage over the pressure mixture of argon and mercury gas to which metal halogenides have been added. Metal halogenides are ionic halogenide salts that are included in the mixture to affect a specific temperature or shade of the lamp.

4 Typical applications of this type of lamp include lighting sports, outdoor lighting, warehouses and factories. The color cast of the lamp properties can also be adapted to simulate daylight closely. Other common uses include the theater, photographic studio of the film. Aquarists of the cliff also use metal halogenides as a light source with high intensity for coral growing.

These lamps are available in a wide selection of energy rating, with the most popular variants 150, 250, 400, 575 and 1,200 watts. Metal halogenide lamps require special assembly to work properly because their high voltage arch requires the inclusion of the ballast in the assembly. However, any additional costs are adequately compensated by good lighting properties and lengthy lifetime. This lamp family cannot create its full bright potential under a certain operating temperature and has a significant "warm -up" period when everyone shines cuddly and changes color. Metal halogenide lamps should ideally be used with enclosed fittings when they are hung above areas with high operations, because the failure of an arc may sometimes cause breaking the outer tube.
