What light fixture is a replacement for a 400 watt metal halide?
The recommended replacement for the 400W metal halide flood is the 120W HyLite LED Prizm, producing approximately 13,000 lumens.
How much does it cost to run a 400W 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.
Why is my metal halide bulb flickering?
With mercury lamps, improper ballasting can cause flickering or erratic operation. With metal halide lamps, the effect is generally noticed in the startup period when the lamp ignites, starts to warm up and then extinguishes (cycling). This may be caused by improper voltage/current relationships delivered by ballast.
What LED to 400 watt metal halide?
Reflection of light inside the fixture reduces lumen output Out of the many factors that play a determining role in the setting of the right lumen amount for the replacement of any 400 watt metal halide, reflection is one. LED lights have directional lighting which directs their lumens to fall on a pre-set point.
What is LED equivalent to 400 watts?
54 Watt
54 Watt (400 Watt Equivalent) T30 High Lumen LED Light Bulb.
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 |
How much does 400w cost per hour?
Often you can run them at 400, 800 or 1200 watts, so that would work out at: 400W = 6 pence per hour. 800W = 12 pence per hour.
How do I know if my Metal Halide ballast is bad?
Signs that a Metal Halide light bulb or ballast needs replaced: The lamp appears to be a different color, or are turning pink.
Do Metal Halide lights need 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 many lumens does a 400 watt HPS put out?
50,000 lumens
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 many lumens do I need to replace a 400 watt metal halide?
How many lumens do i need to replace a 400 watt metal halide with LED? A: To replace a 400 watt Metal Halide you will need abotu 18,000 lumens. This can range from 16,000 lumens if you are replacing at the end of the metal halide life to as high as 25,000 lumens for a brand new bulb.
Why was the 400 watt halide light bulb used?
The 400watt Metal Halide bulb was used extensively for its long lifespan and the high lumens of light it was capable of producing. The efficiency was also better than many other bulbs of that time. These bulbs were available in different watts; however, 400 watts was used most widely because of its highly popular size point.
Is there a 400 watt metal halide grow light?
HTG Supply 400 watt metal halide grow lights can also be upgraded with a variety of great MH bulbs and reflectors or air-cooled hood models. Check out all of the options below and customize the system to fit your personal growing needs.
When did the 400 watt light bulb come out?
These bulbs were available in different watts; however, 400 watts was used most widely because of its highly popular size point. The 400 watt bulbs worked well at 15-20 ft high, a popular range for high bay lights and parking lot lights. They were developed in the 1960s.
