By Where is a metal halide lamp used?
Metal halide lamps are used in gymnasiums, factories, hallways, outdoor sports lighting, and retail displays. These lamps combine good color rendering with high effiency and long life.
How do metal halide lamps work?
To put it simply, metal halide technology works by passing an electrical arc through a mix of gasses, creating light. When the lamp is inactive, the mercury and metal halide salts are condensed inside the inner arc tube. Metal halide lighting features two electrodes –– one on each end of the inner arc tube.
What kind of light is metal halide?
Metal halide lamps generate a very cool white light. They are available in color temperatures as low as 3000K. Some metal halides are available with extremely cool color temperatures up to 20,000K.
How do you test a metal halide lamp?
Check the ballast output with a voltage tester. Turn on the lamp and touch the ends of the tester leads to the lamp electrodes with the bulb in place, then remove the bulb and make the same test. You should get voltage readings in both cases that agree with the output specified on the label.
How long do metal halide ballasts last?
approximately 20,000 hours
Failure to replace a commercial light bulb before complete lamp failure will damage the ballast and cause a drastic increase in maintenance costs. In the case of Metal Halide, most manufacturers rate these HID light bulbs with a life of approximately 20,000 hours.
How many lumens in a 70 watt metal halide lamp?
What is the Lumen Output of a Metal Halide? Metal Halide Wattage Delivered Lumens LED Wattage Equivalent 70 W 5,600 19 W LED 100 W 8,500 23 W LED 175 W 15,000 62 W LED 250 W 22,000 124 W LED
Why do metal halide lamps require a ballast?
Like all other gas-discharge lamps, metal-halide lamps have negative resistance (with the rare exception of self-ballasted lamps with a filament), and so require a ballast to provide proper starting and operating voltages while regulating the current flow through the lamp.
How do you dispose of metal halide lamp?
You should dispose of the metal halide lamp with your area’s household hazardous waste collection. Alternatively, your local recycling center may accept the spent metal halide lamp, if the center accepts hazardous waste.
What does metal halide lamp mean?
A metal-halide lamp is an electrical lamp that produces light by an electric arc through a gaseous mixture of vaporized mercury and metal halides (compounds of metals with bromine or iodine ). It is a type of high-intensity discharge (HID) gas discharge lamp.
