Can you use a 400W high pressure sodium bulb in a metal halide ballast?

No, the ballast has to be matched to the lamp. 250 watt ballast, 250 watt lamp. Also be sure to match the lamp type to the proper ballast even though the wattage is the same. HPS ballast to HPS lamp, Metal halide ballast to metal halide lamp and mercury vapour lamp to mercury vapour ballast.


Is 400w hps better than 400w halide bulb?

yes


How much wattage does a 250w HPS bulb use?

A 250W HPS (High-Pressure Sodium) bulb uses 250 Watts of electricity when it is operating at its full power. It is important to note that the actual power consumption may vary slightly due to factors such as ballast efficiency and voltage fluctuations.


Can you use a 250W Hps bulb in a 400W ballast?

It is not recommended to use a 250W HPS bulb in a 400W ballast as the ballast is designed to work with a specific wattage bulb. Using a lower wattage bulb can lead to inefficient operation, poor light output, and potential safety hazards. It is best to use a bulb that matches the wattage of the ballast for optimal performance.


How does a 400w hps ballast work?

A 400W HPS ballast works by regulating the electrical current that flows through the lamp. It provides the initial surge of electricity needed to start the lamp, then maintains a steady current to keep it lit. The ballast also helps control the temperature of the lamp to ensure proper operation.


Can you split 2 light using 1000w hps ballast?

No, a 1000w HPS ballast is designed to power one 1000w HPS light bulb. If you want to power two lights, you would need to use a ballast with enough power output for two lights, like a 2000w HPS ballast.


Can you use a 1000 watt hps without a ballast?

No, you cannot use a 1000 watt HPS (high-pressure sodium) lamp without a ballast. The ballast is essential for regulating the electrical current flowing through the lamp, which is necessary for it to operate properly and prevent damage. Trying to operate a 1000 watt HPS lamp without a ballast can result in the lamp not lighting up or malfunctioning.


What should voltage be at socket of a 400w hps fixture 120v?

100 Volts


Will a hps luminaire run a metal halide lamp?

Yes the ballast and starter are the same you can run halide in hps, but not hps in halide.


Can a 400 watt high pressure sodium bulb be used in a 400 watt metal halide ballast?

I actually have a 400w hps ballast and I can also use my 400w metal halide bulb in it with no problem. So what your saying is they do, but they dont? the answer is, they dont. You can get universal bulbs hps to plug into a mh ballast they have a miniturized igniter inside the bulb. As I understand it, a 400W metal halide bulb can be used with a 400W hps ballast, but not the converse. A MH bulb has the igniter in the bulb, and the HPS has it in the ballast--which pretty much goes along with your comment above. Apparently the double presence of the igniter in the HPS setup is OK.you can run metal halide in same wattage's but not hps in metal halide systems.you can run such as (same wattage's)250 watt metal halide-400 watt halide ect in hps systems but not hps bulbs in halide systems. they make conversion bulbs to run halide in hps as well and vice versa.


Do you need a ballast for HPS lights?

Yes, all high pressure sodium fixtures require a ballast to operate the fixture's lamp. Most of these industrial fixtures come with a multi tap primary on the ballast so that they can be used on multiple voltages.


Can you use a 150w hps bulb in a 150w mh ballast?

The MH ballast will not have the ignitor required to power up the HPS bulb. I have 1000w ballast that can be switched between HPS and MH with a singe switch just by disabling the ignitor for the MH. I would look into conversion bulbs, or else check out this site for $20 150w HPS ballast with bulb. http://www.e-conolight.com/Product/EProductDetail.asp?ProductFamilyID=7&FGNumber=E-MT6H151G If it doesnt appear, sellect vapor tights, then the 150hps.
