What does metal halide mean?

What does metal halide mean?

A metal-halide lamp is an electrical lamp that produces light by an electric arc through a gaseous mixture of vaporized mercury and metal halides (compounds of metals with bromine or iodine). It is a type of high-intensity discharge (HID) gas discharge lamp.

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. Implementing an LED replacement program should result in a 50% reduction in annual energy use (kWh) costs.

Are metal halide bulbs dangerous?

Some of these MH lamps can cause serious skin burns and eye inflammation if the outer envelope of the lamp is broken or punctured and the arc tube continues to burn, because the arc tube emits UV radiation. Some MH lamps are self-extinguishing-they will automatically extinguish if the outer envelope is broken.

Is metal halide the same as halogen?

Traditional halogen lamps use a filament which heats up as the electricity passes through. This glows, producing light and a lot of heat. ... 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.

Is metal halide better for veg?

Ironically, most HID grow light enthusiasts recommend using both MH and HPS grow lights. MH grow lights (metal halide) are suited best for vegetative growth and HPS grow lights are superior for flowering.

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. ... MH lamp voltage typically increases over time, and the ballast must continue to provide sufficient voltage to the lamp as it ages.

Can you touch a metal halide bulb?

When dealing with Metal Halide bulbs always remember to never touch the bulb with your hands. The natural oils from your finger will contaminate the glass and cause heat to gather in that area and effects the bulb.

How long do metal halide ballasts last?

approximately 20,000 hours

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.

Is Metal Halide good for growing?

Metal Halide (MH) lamps typically emit a white colored light. Traditionally Metal Halide lamps have been used by indoor growers during the vegetative stage of plant growth. They are ideal for growing plants up to the flowering and fruit production stages because they mimic the spring/early summer seasonal sun.

How much does it cost to run a metal halide light?

At an average cost of 0.

Which is better metal halide or high pressure sodium?

HPS is about twice as electrically efficient as metal halide. Photosynthetically Active Radiation (PAR) is what really matters to plant growth, and delivery of usable PAR is better with HPS than metal halide. ... Metal halides deliver, on average, about 000 lumens per standard 1,000-watt bulb.

Is 150 watts enough for 1 plant?

You might want to consider upgrading to at least a 400w hps/mh system. 150 watts hps - 16000 lumens is more than enough for 1-2 plants.

What is the best metal halide bulb for growing?

Best HPS & MH Grow Bulbs: Summary of Recommendations

  • Best overall: EyeHortilux Super HPS.
  • Best budget bulb: Vivosun HPS.

Are metal halide bulbs hotter than HPS?

Wait 'til you hear this! MH IS hotter than HPS. CFL's (up to a point) are cooler than HPS.

How far should metal halide be planted?

7 to 18 inches

Are metal halide lights energy efficient?

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.
