Metal halide lamps can explode if they operate at high pressures, but some products are manufactured with safety features in mind. If the outer envelope is broken, some lamps self extinguishing.

How can you tell if a metal halide bulb is bad?
When compared to other lamps in the same system, the lamps gain a brownish hue. This is caused by expired metal vapors in the lamp and the lack of a particular mixture in the arcs tube.
How do you test a metal halide bulb?
The output of the ballast should be checked by a voltage tester. After turning on the lamp and touching the ends of the tester, you can remove the bulb and make a test. If you agree with the output on the label, you should get a voltage reading.
How do you troubleshoot a metal halide light fixture?
If the lamp is loose in the sockets or the base is distorted, the lamp won’t seat correctly. Poor connections, loose contacts, or broken wiring can be found in the sockets. High pressure sodium and low watt metal halide lamps need a starter that has a high voltage pulse.
Why is my metal halide bulb flickering?
Mercury lamps can have flickering or erratic operation if they are not properly ballasted. The effect is usually seen when the lamp starts to warm up and then extinguishes. It is possible that this is caused by improper voltage/ current relationships delivered by ballast.
Can you replace metal halide bulbs with LED?
Long life, lower energy costs, and control options are offered by the light emitting device. A 200 watt light emitting device can be used to replace a 400 watt bulb. A 50 watt LED can be used to replace a 100 watt metal halide. A 50% reduction in annual energy use costs can be achieved with the implementation of an LEDs replacement program.
What happens if you touch a metal halide bulb?
It is possible to get on the bulb with your hands. Hot spots on the bulb can be caused by this.
Can you touch metal halide?
It is going to be a challenge for you. If the point on the bulb becomes a heat sink and the glass temperature on that point becomes unstable, the bulb may explode. It’s the same reason that you don’t want the water to get into the machine.
Can a metal halide bulb explode?
Metal halide lamps can explode if they operate at high pressures, but some products are manufactured with safety features in mind.
Are metal halide bulbs dangerous?
Eye and skin injuries are caused by broken and unshielded metal halide and mercury vapor light bulbs.
What happens if you touch halogen bulb?
It’s a good idea to keep the Glass out of the bulb. This is because when you touch a Halogen Light Bulb, you leave a mark on the light bulb which can cause it to heat up unevenly, and even cause it to shatter.
Do metal halide bulbs wear out?
The bulbs should be replaced after 6 to 10 months of use. HPS bulbs depreciate due to the initial voltage spike, operation temperature, and age of the ballast being used.
What is the average life of a metal halide lamp?
The lifespan of metal Halide lights is better than that of old technology, but they have a shorter lifespan than LEDs. Bulb lifespans range from 6,000 hours to 15,000 hours before they need to be replaced.
Are metal halide bulbs expensive to run?
A system of 1,000 400 watt Metal Halide fixture costs $42.22 per hour at an average cost of 0.10 cents per kilowatt. $30.09 per month in energy per fixture is what it would cost if the fixture ran an average of 730 hours a month.
When should metal halide bulbs be replaced?
The bulbs need to be replaced every 8 months. You lose 40% of your yield when you lose 40% of your output.
How long do metal halide ballasts last?
The life expectancy of high quality ballasts is between 20,000 and 60,000 hours. The quality of components and operating temperature are the most important factors in determining life.
How long do metal halide lamps last?
What causes metal halide lamps to explode?
It’s possible that too much current could cause the active component of the MH to become overheated. You have to be aware of that as well. The lamp would be destroyed by the same heat surge as before.
Do metal halide bulbs dim over time?
Within 6 months your new light will be less than 30,000lm. The lm of metal halides is lost very quickly. lm depreciation is at 50% after 4,000 to 10,000 hours of life. lm loss due to reflected light is not taken into account.
Do metal halide bulbs require ballast?
It is necessary to start the lamp, regulate the lamp starting and lamp operating currents, and provide appropriate sustaining supply voltage with the use of metal halide (MH) ballasts. The lamp’s voltage can change over time, and the ballast needs to keep providing enough power to the lamp.
How do metal halide lamps work?
Metal halide technology works by passing an electricalarc through a mix of gasses and creating light. Mercury and metal halide salts can be found inside the inner arcs of lamps. There are two wires on the inner arcs of the lighting.
