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.
Metal halide (MH) lamps can explode (typically referred to as sudden nonpassive failure) because they operate at high pressures, but some products are manufactured with safety features to prevent injury.
Subsequently, question is, does metal halide contain mercury? 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.
Also know, what are metal halide bulbs used for?
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.
Can I replace metal halide with LED?
LED Offers Long Life, Lower Energy Costs, Instant On and Control Options. 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.
Do metal halide bulbs get hot?
When fully lit, the Metal Halide lamp will reach a temperature of 2000 degrees Fahrenheit and operates at a vapour pressure between 70 and 90 pounds per square inch. Normal use of Metal Halide lighting requires that they are very rarely, if ever shut off.
How long does a metal halide bulb last?
Metal 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 dispose of metal halide bulbs?
The LampMaster Metal Halide Bulb Recycling Kit is a simple, but effective way to make sure you are staying in compliance with the Environmental Protection Agency. It is important and environmentally responsible for households to recycle metal halide or high pressure sodium lamps and all types of mercury waste.
What is the difference between halogen and metal halide?
Traditional halogen lamps use a filament which heats up as the electricity passes through. Metal Halide and Sodium Vapour are discharge lamps, much like a fluorescent tube, where the gas is the lamp is glowing, rather than a filament like with halogen.
Why do metal halide bulbs explode?
Metal halide lamps contain high-pressure gases in the arc tube. In the case of non-passive failure, the pressurized arc tube within the lamp causes the explosion. When the arc tube explodes, molten glass can fall from the fixture, which presents an obvious issue if a fixture is installed above flammable materials.
What’s the difference between metal halide and mercury vapor?
The metal halide lamp is very similar in construction to the mercury vapor lamp. The major difference is that the metal halide lamp contains various metal halide additives in addition to mercury vapor. Ballasts designed specifically for metal halide lamps must be used.
Which is better metal halide or high pressure sodium?
High pressure sodium lamps last longer than metal halide; they also produce more lumens per watt. Because of their mercury content, neither type of lamp is particularly good for the environment. Metal halide lamps produce more of a glare compared to high pressure sodium lamps.
How much heat does a 400 watt metal halide produce?
For instance a 400 Watt Metal Halide High Bay lamp puts off 1,364 BTUs per hour vs. a 150 Watt LED High Bay puts off 511 BTUs/hr. If you have 100 High Bay fixtures that burn for 18 hours per day, that’s 896 Million BTUs vs.
Is metal halide for flowering?
Metal Halide Grow Lights Metal Halides are another specific type of HID grow light. HPS-like MH bulbs are still simply not as effective as having a full-fledged HPS light to flower your plants under though due to the significant difference in light intensity.
Can you use metal halide bulb HPS ballast?
Conversion bulbs allow you to run HPS bulbs on a MH ballast, or a MH bulb on a HPS ballast. HPS ballast have an igniter and MH ballasts do not. That is the only difference. An igniter is an electrical component that ignites the sodium in the HPS bulb.
Why does my metal halide light go on and off?
Metal Halide Lamps Normal end-of-life is caused by sodium loss from the arc tube. The lamp may be hard to start. High Pressure Sodium Lamps Normal end-of-life is usually indicated by the lamp cycling on and off.
How long does it take for a metal halide to turn on?
Metal halide (MH) lamps do not achieve their full light output immediately after starting. Rather, they require a period of time-1 to 15 minutes-to reach 90% of their full light output. This period is called the warm-up (or run-up) time.
What is the difference between metal halide and ceramic metal halide?
Lets take a look at a Metal Halide Lamp. A CMH lamp has a different emitter than a normal metal halide lamp, which is built of Quartz. Inside a CMH there is a ceramic component. So the difference is this – A ceramic tube is able to withstand much higher temperatures.
Are HPS and metal halide interchangeable?
Unfortunately not all ballasts allow both the MH and HPS bulbs to be interchangeable. While some do, it’s never a good idea to assume both can be utilized. However, it is possible to swap out both a MH and an HPS with the use of a Conversion bulb.
