Xenon arc lamps are gas discharge lamps operated with continuous current (DC). An electric arc, flowing through two electrodes inside a bulb ionized with xenon gas at high pressure, produces a bright white light closely to the natural sunlight. Xenon arc lamps have a wide range of application such as are used in movie projectors, in theaters, in searchlights and for specialized industry uses and in solar simulation.
Low ripple and a very stable current assure these lamps a long life.
Xenon lamps are also chosen also for the fact that the re-ignition at any stage of cooling is possible. When started, also from cold state, the full light output is immediately achieved.
METAL HALIDE LAMPS
Having an excellent colour rendering and photometric integrity throughout their life metal halide discharge lamps, are AC- operated. The colour temperature that closely matches sunlight is generated by metal halide discharge lamps, having an extremely bright light, providing up to 100 lumens per watt. Due to the fact that it reveals true colours it facilitates daytime filming outdoors.
Metal halide lamps are up to five times more efficient than an incandescent light, dimmable and have hot restart capability.
Metal Halide lamps are the first choice in the film and TV industry.
HID lamps (high-intensity discharge lamps) are electrical gas-discharge lamps that produces light by means of an electric arc between tungsten electrodes housed inside a translucent or transparent fused quartz or fused alumina arc tube. The tube is filled with both metal salts and gas.
When high levels of light over large areas are required, HID lamps are typically used, and when energy efficiency and/or light intensity are desired. These areas include large public areas gymnasiums, warehouses, football stadiums, movie theaters, outdoor activity areas, roadways, parking lots, and pathways.
