What are metal halide lamps used for?
Uses. Metal-halide lamps are used for general lighting purposes both indoors and outdoors, such as commercial, industrial, and public spaces, parking lots, sports arenas, factories, and retail stores, as well as residential security lighting; automotive and specialty applications are further fields of usage.
What produces the light in a metal halide lamp?
A metal-halide lamp is an electric light that produces light by an electric arc through a gaseous mixture of vaporized mercury and metal halides[1][2] (compounds of metals with bromine or iodine). It is a type of high-intensity discharge (HID) gas discharge lamp.
Do metal halide lamps need 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.
What is in a metal halide lamp?
With a metal halide lamp, that mix of gases will normally include mercury, xenon or argon, and a variety of metal halides. Metal halides are produced as a result of combining halogen with a metal. In metal halide lamps, that is normally metals that have been mixed with iodine or bromine.
Which is better metal halide lamp vs LED?
Both metal halides and LEDs are considered to be more energy-efficient than incandescent lamps. However, when it comes down to the numbers, the energy efficiency of an LED far exceeds that of a metal halide lamp. A new 400-watt metal halide lamp is rated to last up to 20,000 hours.
What is the gas in a metal halide lamp?
Metal halide (MH) ballasts are required to start the lamp, regulate the lamp starting and lamp operating currents, and provide appropriate sustaining supply voltage.
What is the difference between halogen lamps vs metal halide lamp?
A metal-halide lamp is an electric light that produces light by an electric arc through a gaseous mixture of vaporized mercury and metal halides[1][2] (compounds of metals with bromine or iodine).
How does a metal halide lamp work?
The basic operation principle of a metal halide lamp is that of a gas discharge lamp. Due to an electric discharge, one generates a plasma, which emits light in the form of spontaneous emission after excitation of atoms or ions, e.g. by electron bombardment. There can also be a significant amount of thermal radiation.
How are metal halide lamps made?
A metal-halide lamp is an electric light that produces light by an electric arc through a gaseous mixture of vaporized mercury and metal halides[1][2] (compounds of metals with bromine or iodine).
Do metal halide bulbs emit UV?
Metal halide (MH) lamps consist of an arc tube (also called a discharge tube or x26quot;burnerx26quot;) within an outer envelope, or bulb. The arc tube may be made of either quartz or ceramic and contains a starting gas (usually argon), mercury, and MH salts.
How do you bypass a metal halide ballast?
lead circuit ballast
What ballast type is commonly used with metal halide lamps?
Pulse-start metal-halide bulbs don’t contain a starting electrode which strikes the arc, and require an ignitor to generate a high-voltage (1u20135 kV on cold strike, over 30 kV on hot restrike) pulse to start the arc. Electronic ballasts include the igniter circuit in one package.
Do metal halide lamps need igniters?
A 400 watt metal halide bulb can be replaced with a 200 watt LED. A 100 watt metal halide can be replaced with a 50 watt LED. Implementing an LED replacement program should result in a 50% reduction in annual energy use (kWh) costs.
Are metal halide bulbs toxic?
A metal-halide lamp is an electric light that produces light by an electric arc through a gaseous mixture of vaporized mercury and metal halides[1][2] (compounds of metals with bromine or iodine).
Is metal halide brighter than LED?
At approximately 100,000 hours, that means an LED not only stays brighter longer, it also lasts three to five times as long as a metal halide version. For more on an LED’s lumen efficiency, read our blog Understanding Luminous Efficacy!
Can I replace metal halide with LED?
A 400 watt metal halide bulb can be replaced with a 200 watt LED.A 100 watt metal halide can be replaced with a 50 watt LED. Implementing an LED replacement program should result in a 50% reduction in annual energy use (kWh) costs. It may also lower electric demand (kW) charges.
WHAT LED is equivalent to 400W metal halide?
The recommended replacement for the 400W metal halide flood is the 120W HyLite LED Prizm, producing approximately 13,000 lumens.
WHAT LED is equivalent to 250W metal halide?
250 Watt Metal Halide u2013 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.
What gas is in a metal halide bulb?
In a nutshell, a MH lamp works when an electrical arc goes through a gaseous mix, creating light. With a metal halide lamp, that mix of gases will normally include mercury, xenon or argon, and a variety of metal halides

What are the advantages of metal halide lamp?
What’s the Upside to Metal Halide Lights? Metal halide lights are 3-5 times as efficient as incandescent bulbs and produce a much higher quality light. In many cases, and depending on the particular mix of metal halides, they have a very high color temperature (up to 5500K).
Can I put a metal halide bulb in a regular socket?
This is why a metal halide bulb will not work in a standard household lighting fixture u2014 aside from the fact that the larger E39 base will not fit. Similarly, a standard incandescent bulb would never be able to withstand the ballast voltage in a metal halide fixture.
How long do metal halide bulbs take to turn on?
Metal halide lamps produce light by passing an electric current through a combination of mercury and metal halide gas. They function very similarly to other gas-discharge lamps (e.g. mercury vapor) – the principal difference being the composition of the gas.
Are metal halide lights being phased out?
Metal halide lamps produce light by passing an electric current through a combination of mercury and metal halide gas. They function very similarly to other gas-discharge lamps (e.g. mercury vapor) – the principal difference being the composition of the gas.
