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.
How long do Metal Halide bulbs 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.
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.
Are metal halide bulbs expensive to run?
At an average cost of 0.09 cents per kilowatt, a system of 1,000 400-watt Metal Halide fixtures costs $41.22 per hour. If the fixtures run an average of 730 hours every month (730 x $41.22), it ends up costing $30,090.60 every month or $30.09 per month in energy per fixture.
How can you tell if a metal halide bulb is bad?
Usually the lamps will gain a pinkish hue when compared to other lamps in the same system. This is caused when metal vapors in the lamp are expired from heat or burning, and the lack of a particular mixture in the arc tube renders a different color.
Can you touch metal halide bulb?
Trust me, “keep yoru mitts off Mh bulbs.” The alcohol wipe advice is right on….. The oils and etc on your hands can get on the bulb. This can cause etching and hot spots on the bulb that can cause issues. f you do touch it just wipe the bulb down with some rubbing alcohol on a napkin or paper towel or something….
How often should you change metal halide bulbs?
MH (Metal Halide) bulbs need to be replaced every 8 months on a 18 hour on 6 hour off cycle. MH bulbs lose 40% output in a year, so you lose around 40% yield. Problems like the light going on & off with power outages make the life of the bulb even shorter.
Can you replace metal halide bulbs 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.
How much heat does a 250 watt bulb produce?
Therefore, if the heat lamp you purchase has 250 watts with a 10% lighting efficiency, it means that the amount of heat it produces is at 225 watts. Heat lamps are widely used in raising chicks due to the ample amount of heat they provide.
How does a metal halide ballast work?
MH lamps start when their ballast supplies a high starting voltage higher than those normally supplied to the lamp electrodes through a gas mixture in the arc tube. … In addition to supplying the correct starting voltage, the ballast also regulates the lamp starting current and lamp operating current.
What is a protected metal halide lamp?
Protected metal halide lamps are made for open fixtures and have a tubular piece of glass around the arctube to prevent glass breakage. These are typically called an MP metal halide such as MP170 or MP400 as an example. They’re often used in fixtures where they might be in close proximity to public areas.
What are energy saving bulbs?
What are energy-saving light bulbs? Energy saving light bulbs (or energy-efficient light bulbs) last up to 12 times as long as traditional bulbs, using less electricity to emit the same amount of light as a traditional bulb. They’re an energy efficient option, helping you to reduce the carbon footprint of your home.
What causes metal halide lamps to explode?
It might be letting too much current — which would overheat// over pressurize the active component of the MH. So you have to be on the watch for that, too. Voltage spikes would produce the same heat surges, again, destroying the lamp.
How long do Gavita bulbs last?
4000 – 5000 hours (HPS) 3000-4000 hours (CDM) 2000 – 3000 hours (MH) 30,000 (Gavita LEP)
How often should you change HID bulbs?
According to average estimates, HID headlights generally last 2,000 hours. That said, some of the most durable HIDs can last up to four times as long.
How does a metal halide lamp work?
To put it simply, metal halide technology works by passing an electrical arc through a mix of gasses, creating light. … When the lamp is inactive, the mercury and metal halide salts are condensed inside the inner arc tube. Metal halide lighting features two electrodes –– one on each end of the inner arc tube.
How do you troubleshoot a metal halide light fixture?
Check to see if the lamp is loose in the socket or if the base is distorted so that the lamp will not seat properly. Check socket for loose contacts, poor connections, or broken wiring. High pressure sodium and low-wattage metal halide lamps require a starter that provides a high-voltage pulse to start the lamp.
What are the signs of a bad ballast?
2. Look for warning signs that the ballast is failing.
- Buzzing. If you hear a strange sound coming from your bulbs or light fixture, like a buzzing or humming noise, that’s often a sign your ballast is going. …
- Dimming or flickering. …
- No lights at all. …
- Changing colors. …
- Swollen casing. …
- Burn marks. …
- Water damage. …
- Leaking oil.
What’s better HPS or metal halide?
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 80,000-110,000 lumens per standard 1,000-watt bulb.
Do all metal halide bulbs require ballast?
MH bulbs, like all HID bulbs, require a ballast to operate and are designed to use a compatible ballast which works with one of these two start methods. Traditional MH bulbs are designed to operate on ballasts using probe start technology, while newer lamps use more efficient pulse start technology.
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 many lumens does a 250 watt metal halide put out?
How many lumens is a 250w metal halide? Depending on how efficient the metal halide bulb is (between 60 and 110 lumens per watt), a 250W metal halide bulb can produce around 15,000 to 25,000 lumens. Keep in mind these are initial lumens and these will typically fall within the first 6 months.
