Can I use a metal halide bulb in a mercury vapor fixture?
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.
What is the difference between metal halide and high pressure sodium?
What is the Difference Between Metal Halide and High Pressure Sodium? Both Metal Halide and High Pressure Sodium bulbs are part of the HID family of bulbs. The primary visual difference between them is that metal halide light is white and the light emitted from a High Pressure Sodium bulb is amber orange.
How hot does a metal halide bulb get?
2000 degrees Fahrenheit
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.
How many watts does a 400W metal halide use?
461 watts
System watts are the total watts the lamp and the ballast use together. The system watts for a 400 watt metal halide is about 458 watts depending on the ballast….What is the difference between lamp watts and system watts?
Metal Halide (MH) High Pressure Sodium (HPS) | System Watts (approximate) |
---|---|
250w MH | 295 watts |
400w MH | 461 watts |
1000w MH | 1080 watts |
250w HPS | 295 watts |
Can you test a metal halide bulb?
Look inside the ballast for a blown fuse and replace it with an intact fuse. 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.
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.
