What is the difference between HPS and MH lights?

Metal Halide (MH) lamps provide more of the blue spectrum, which is ideal for leafy crops, and/or plants that are in a vegetative stage. High Pressure Sodium (HPS) lamps provide more yellow/red spectrum, which is ideal for most plants that are actively fruiting and flowering.

What is the difference between multi vapor and metal halide?

There is no difference between metal halide and multi vapor lamps because both names describe the same form of lamp. Metal halide or multi vapor lamps are a form of the light source that creates light via passing an electric arc through a gaseous mixture of mercury vapor and vapor of some metal halides.

Can I use a metal halide bulb in a mercury vapor fixture?

They do not manufacture “mercury vapor” ballasts anymore, so you would use a metal halide ballast and MH or MV lamp. On occasion, pairing a 175 MV lamp with a 150W MH ballast, will work, but will cause the ballast to overclock, and will greatly shorten the life of that ballast and/or lamp.

Is HPS stronger than MH?

In addition, HPS lights provide higher light intensity (lumens) than MH. This can be around 25-40% more lumens/watt than MH lights of the same wattage, and when it comes to flowering; the more light – the better the results.

What are metal halide lamps 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.

Will a metal halide ballast run a mercury vapor lamp?

You will may run into some issue with using MV ballast with MH bulbs techally it will work but safety point no.,, unless you have open bulb rated then it will be fine.

Can you use metal halide bulbs in a high pressure sodium fixture?

Both Metal Halide and High Pressure Sodium bulbs are part of the HID family of bulbs. These bulbs cannot be interchanged without changing their ballast, the regulating element in all light bulbs.

Is metal halide better than LED?

LEDs tend to last much longer and are a more energy efficient and less maintenance intensive technology. Metal halides have long warm-up periods and a shorter lifespan but produce a very high quality light and are one of the most efficient lights when it comes to very cool color temperature outputs.

What’s the difference between metal halide and high pressure sodium lamps?

Metal Halide: Metal halides are used in metal halide lamps along with mercury. High Pressure Sodium: High pressure sodium lamps are used for lightening purposes and in plant growth stimulation.

How much mercury is in a metal halide lamp?

Mercury is a dangerous substance found in all high intensity discharge light bulbs. Mercury should be kept out of landfills both because it is dangerous and because it is easily recyclable. A standard 250 watt metal halide lamp contains around 38 mg of mercury, a 250 watt high pressure sodium lamp contains around 15 mg.

How long does a high pressure sodium lamp last?

A 250 watt high pressure sodium lamp can last from 12,000 to 24,000 hours. A 250 watt metal halide lamp will last from 10,000 to 15,000 hours. Metal halide lamps produce light in the white and blue spectrums, while high pressure sodium lamps produce light in the yellow, orange and red spectrums.

Which is better metal halide or incandescent light?

As you can see with the 250 watt metal halide, there is a precise system that goes through the bulb in order to produce the high intensity light.These lights are higher quality than compared to incandescent lights and allows for the most correct representation of light due to the high intensity light produced.
