First of all, Ceramic Metal Halide and Metal Halide bulbs are not the same thing. Even if they share a lot of the same technology they have fundamental differences in the way they’re constructed and how they operate. You can’t just use your new CMH bulb in your old MH ballast. Trying to do so would be very dangerous.
Is MH and CMH the same?
The largest difference between MH and CMH lamps is the Ceramic or “C” in CMH. Another advantage when using the CMH lamp, is the lower wattage – it is only 315 watts, compared to a metal halide lamp which is often 600-1000 watts.
Are high pressure sodium metal halides interchangeable?
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. Their operation is a bit different and they therefore require different ballasts.
Is there a difference in metal halide bulbs?
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).
Are metal halide bulbs being phased out?
Given metal halide is a declining technology under strong direct competition by solid-state lighting, a significant number of products may have been discontinued. In other cases, luminaires may have been redesigned for a different ballast and then retested.
Is CMH better than MH?
Balanced spectrum This means that CMH are more PAR efficient than either HPS or MH, making them a better single light solution.
What is a CMH in healthcare?
For more than a century, Community Memorial Hospital (CMH) has been the healthcare leader in Ventura County. Today, the six-story, 250-bed nonprofit facility has become a state-of-the-art regional hospital and health center, providing a vast array of medical services and programs.
Are all HPS bulbs the same?
HPS bulbs also come in many different sizes, making them a flexible pick for your indoor garden. As a general rule, 400w HPS bulbs are the most common, 600w HPS bulbs are the most efficient, and 1000w HPS bulbs are the most powerful (but also the hottest).
Can you replace high pressure sodium bulb with LED?
High pressure sodium bulbs (“lamps”) are an old standby for lighting that’s still used today in spite of so much talk of LED lights. LEDs, however, are better able to control their light, which is why a lower-watt LED can replace a higher-watt high pressure sodium bulb.
Can you put a HPS bulb in a MH ballast?
Some conversion bulbs allow MH light to work with HPS ballasts, and others let HPS work with MH ballasts. So, for example, if you want to use an MH bulb that boosts red and blue wavelengths in your HPS fixture, it’s possible the minute your bulb is cool enough to change out.
What are the different types of metal halide bulbs?
Metal halide lamps are available in several different base types, with medium (E26) or mogul (E39) bases being the most common. They also have clear, coated, or shatter resistant lenses. These lamps come in assorted color temperatures and multiple burn positions.
Can I use a higher wattage metal halide bulb?
Yes you can use the same mogul for both wattages,just do not fire a 175w bulb on a 250 ballast and or 250 on 175.
Can you use a LED bulb in a metal halide fixture?
Light-emitting diode (LED) technology advancements now allow you to retrofit your metal halide lamps with a simple bulb change. LEDs can give you comparable lumens at a fraction of the energy cost. They are also longer-lived and show a lower reduction of performance over their service life.
How long does a Metal Halide ballast last?
In the case of Metal Halide, most manufacturers rate these HID light bulbs with a life of approximately 20,000 hours. This rating traditionally means the point in which 50% of the lamps will fail, but in the case of maintenance, this is the DO NOT EXCEED time of all lamps.
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.
How hot does a Metal Halide bulb get?
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.
Is CMH good for flowering?
CMH bulbs are great for flowering, too, but not as good as HPS bulbs. They are much better at vegging though, making them the perfect full-cycle bulbs. CMH lamps are generally a bit more expensive than their HPS counterparts, but they make up for it with double the usable lifespan.
Is CMH better for veg or flower?
A recent addition to the market is Ceramic Metal Halide (CMH) bulbs. This makes them ideal for growing from seed to flower with the one bulb. You will get more growth during the veg stage due to the higher efficiency and less stretching in the flower stage due to the high percentage of blue in the spectrum.
Are CMH lights bad for your eyes?
CMH emits large amounts of ultraviolet (UV) light. This stresses plants, making them heartier and triggering production of turpines and THC. However, the effects of UV exposure on humans include cataracts, macular degeneration, pingueculae, pterygia—and skin cancer.
What does CMH stand for?
CMH Acronym Definition CMH Center for Minority Health CMH Children’s Memorial Hospital CMH Centre for Medical Humanities (Durham Univeristy; UK) CMH Congressional Medal of Honor.
Who is the CEO of Community Memorial Hospital?
Gary K. Wilde is President and CEO of Community Memorial Health System (CMHS), a regional health system of two hospitals of 345 beds and a network of ambulatory care centers with over 300,000 annual patient visits. He has served in that capacity for thirteen years.
