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.

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.
Will a higher wattage hps bulb work in a ballast that came with a lower wattage bulb?
A higher wattage HPS bulb may work with a ballast that is rated for a lower wattage bulb , but may appear to be dim and will not produce the rated light output. It is best to match ballast and bulb accordingly.
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.
How many lights to grow 4 plants?
No you would need a 400 watt hps lamp for flowering but you could probably use that cfl for the veg period
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.
Can you run a 250w hps through a 400w hps ballast?
No!
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.
4 250 mh bulbs 1 1000 watt mh ballast how to wire?
I would wire them together in a parellel circut. all the lights together, white to white black to black then put your ballast to em. it works like that with my 400 watt mh/hps ballast and 2 250 watt hps bulbs. run 2 hps bulbs with 2 mh bulbs if you can, you get better results.
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.
When you need to use metal halide conversion bulb?
When you want to use a MH bulb in an HPS ballast you must use a conversion bulb. It must be the same wattage as the HPS bulb
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.

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.

A higher wattage HPS bulb may work with a ballast that is rated for a lower wattage bulb , but may appear to be dim and will not produce the rated light output. It is best to match ballast and bulb accordingly.
Is a ballist use on a hid light?
Yes, HID lights need a ballast.
Where can one purchase some HPS lights?
HPS lights aren't a product that would be sold at just any store. One would need to visit a home improvement store such as the Home Depot, Lowe's, or Ace Hardware to purchase these specific types of lights. These stores would provide several different options in lighting for a home garden system.
