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.
What is the lumens for 400w metal halide lamp?
The initial lumens for a 400W metal halide lamp is approximately 36,000. This is the amount of light that is produced the first time the lamp is turned on. All lamps have some form of lumen depreciation. A better gauge for the lumen output of a particular lamp is the mean lumens.
Can you replace a metal halide bulb with an LED bulb?
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 much heat does a 400 watt metal halide produce?
1,364 BTUs per hour
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.
WHAT LED is equivalent to 400w HPS?
As a side note: A 400-watt HPS luminaire initially supplies about 50,000 lumens. The rule of thumb is to reduce the HPS lumen output by half to determine the LED lumen output, which would be 25,000 lumens in this case.
How much does it cost to run a 400 watt metal halide?
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.
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. The enhanced blue in metal halide does not lead to increased plant growth compared to HPS in the “veg” stage.
How much electricity does a 400 watt Metal Halide use?
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) |
|---|---|
| 400w MH | 461 watts |
| 1000w MH | 1080 watts |
| 250w HPS | 295 watts |
| 400w HPS | 460 watts |
How can you tell if a metal halide bulb is blown?
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.
Which is better metal halide lamp vs 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.
