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
Can you use a 250W Hps bulb in a 400W ballast?
NOT PROPERLY Although it may light, it will burn out pre-maturely due to the higher current flow. A ballast and its lamp must always be a proper match in any HID (high intensity discharge) application. The 400 watt rating of your ballast is NOT a maximum rating. It is 400 and only 400.
How much wattage does a 250w HPS bulb use?
hps light averages 125 lumens, therefore, a 150 watt hps light is about 18,750 lumens.
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, a ballast is required for HPS (high-pressure sodium) lights. The ballast helps regulate the electrical current and provides the initial high voltage needed to start the lamp. Without a ballast, the HPS light would not function properly.
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.
Running watts for a hps lamp?
The formula you are looking for is W = Amps x Volts. Find the amperage and voltage that is on the nameplate of the HPS fixture's ballast.
Can a hps light fixture be plugged in to a regular outlet?
If the ballast of the HPS fixture has a 120 volt tap then, yes it can be plugged into a 120 volt receptacle.
Can you use a 100 watt metal halide bulb in a 150 watt lamp?
Not recommended. It would work but shorten lamp life and may cause risk of fire. However, if you just wanted to check a lamp was capable of striking it would be ok for a few minutes. I've done the opposite in the past and used a 150w lamp with a 100w ballast. Works, but not good for any of the components, including lamp.
