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.
How to replace a 250 watt metal halide?
250 Watt Metal Halide – 100 Watt LED Equivalent for Replacement. The 250-Watt metal halide bulbs have various applications such as airport, warehouse, parking lot, retail stores, football pitch, tennis court, sports stadium and more. Replacement of 250W MH flood lamp with LED equivalent (100W) has a lot of advantages.
Why do metal halide lamps require a ballast?
Why do metal halide lamps require a ballast? Metal halide (MH) ballasts are required to start the lamp, regulate the lamp starting and lamp operating currents, and provide appropriate sustaining supply voltage. (See " What are warm-up and restrike times for metal halide lamps ?")
Can I replace metal halide with led?
We can replace the 400-watt metal halide lamp with a 150-watt LED light. A 40W LED light can replace a 100W metal halide lamp. Regardless of whether it is a home, school, factory, sports field or parking lot, the use of LED lights will reduce the cost of annual energy use (kWh) by at least 60%. The most intuitive result is a significant reduction in electricity demand (kW) costs.
How do you dispose of metal halide lamp?
There are also four types of regulated participants in the universal waste system:
- Small quantity handlers of universal waste (accumulates less than 5,000 kg of universal waste),
- Large quantity handlers of universal waste (accumulates 5,000 kg or more of universal waste),
- Universal waste transporters and,
- Universal waste destination facilities.
How do you test a metal halide bulb with a multimeter?
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 do I know if my metal halide ballast is bad?
Signs that a Metal Halide light bulb or ballast needs replaced: The lamp appears to be a different color, or are turning pink.
How do you troubleshoot a metal halide light fixture?
Check to see if the lamp is loose in the socket or if the base is distorted so that the lamp will not seat properly. Check socket for loose contacts, poor connections, or broken wiring. High pressure sodium and low-wattage metal halide lamps require a starter that provides a high-voltage pulse to start the lamp.
What causes a metal halide to go off?
With metal halide lamps, the effect is generally noticed in the startup period when the lamp ignites, starts to warm up and then extinguishes (cycling). This may be caused by improper voltage/current relationships delivered by ballast. Under certain conditions new lamps may "cycle".
How do I test a ballast with a multimeter?
To measure it, set your digital multimeter to around a thousand ohms resistance setting. Connect the black leads to the white ground wire on your ballast. Afterward, test every other wire with the red lead. When you do this test, a good ballast will return an “open-loop” or max resistance.
What are the signs of a bad ballast?
If your fluorescent lighting is displaying any of the signs below, it could be a symptom of a bad ballast:Flickering. ... Buzzing. ... Delayed start. ... Low output. ... Inconsistent lighting levels. ... Switch to an electronic ballast, keep lamp. ... Switch to an electronic ballast, switch to a T8 fluorescent.More items...•
How long do metal halide bulbs last?
6,000 hours to 15,000 hoursMetal Halide lights have an better lifespan relative to old technology like incandescent lights but they have a short lifespan compared to LED. Typical lifespan values range from 6,000 hours to 15,000 hours before a bulb requires replacement.
How do you test a metal halide capacitor?
The proper test procedure is as follows: - Disconnect the Metal Halide, High Pressure Sodium or Pulse Start capacitor from the circuit and discharge it by shorting the terminals or wires together. - If the meter indicates a very low resistance then gradually increases, the capacitor does not require replacement.
Do metal halide bulbs require ballast?
Metal halide (MH) ballasts are required to start the lamp, regulate the lamp starting and lamp operating currents, and provide appropriate sustaining supply voltage.
Are metal halide lights being phased out?
Most marine reef hobbyists preferred metal halide or T5 lighting technology because of cost consideration and that they will grow coral in reef aquariums. This fact remains undisputed but there are other costs to consider beside the cost of the lighting.
How do you change a metal halide ballast?

What is metal halide?
I don't think so. A metal-halide is a type of HID lighting, which means it uses an electrical arc to produce light instead of a filament. If there's no arc, there's not gonna be any continuity.
How much does a bulb cost?
Depending on the specific fixture, a bulb might cost you $8 or $40. It really helps to know ahead of time exactly what parts you will need.
Can a metal halide lamp be black?
An old metal halide lamp the arc tube will be black, most of the time but not all that arc tube will shatter at the end of life and sometimes the outer glass will shatter as well if that is the case you will need a heavy pair of needle nose pliers to to remove the base of the lamp.
What happens if you turn off a metal halide lamp?
Tip. When you switch off a metal halide lamp after it has been burning for a while, it may need to cool down before it will go on again. If the wire connecting the lamp to the house circuitry is too thin, the ballast may not be able to develop sufficient power to start the lamp. Warning.
Why do HID lamps need a ballast?
Like fluorescent lamps, HID lamps produce light by the excitation of a gas confined between a pair of electrodes and require a ballast to limit current draw and to provide proper starting and operating voltages. If your metal halide lamp does not start or burns irregularly, there may be a problem with the ballast or the bulb.
How many volts does a ballast need?
If the lamp has never been operational, make sure the wiring agrees with the diagram on the ballast label. Be sure the voltage supplied to the ballast is correct. Some ballasts require 240-volt power, supplied by two hot wires carrying 120 volts each and connected to two separate breakers in the panel. Advertisement.
What happens if a lamp turns on?
If it turns on, the circuit is probably overloaded.
Is a metal halide lamp a high temperature?
Warning. Metal halide lamps operate at a high temperature. Always let a lamp cool down completely before you touch it. The color temperature of lighting produced by metal halide lamps is close to natural sunlight. Metal halide lamps belong to a family of high intensity discharge (HID) lamps that includes mercury-vapor and sodium-vapor lamps.
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.
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.
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.
How long do metal halide lamps last?
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.
