I have a 400 watt bulb in mind to use. Can this ballast accept a 400 watt MH with the dimmer feature?

im sure you could but then thats kind of a waste cause if your not using a 400w ballast then the red and the blues are not correct for the bulb

So the dimmer features works on percentages, 100, 75, or 50, 50% is too low at 300 watts and 75% would be to high at 450 watts....you worried about heat with the 600 or u got a better quality bulb at 400?

Its honestly not much more for a 600 watt bulb and its akways best to keep the bulb and ballast matched...you can always dim the 600 watt...just a suggestion. I would hate to see someone loose money on a ballast due to mix matched wattages...be safe rather than sorry. I hope this helped.

50 extra watts as long as you vent your cool tube correctly wont make much of a heat difference at all.

I'm not absolutely sure. This ballast is for 40w T12 (1-1/2" diameter) bulbs. It is not designed for the T8 (1" diameter) bulbs. If you have a fixture with the 1-1/2" diameter bulbs, it should work. As others have said, a wiring diagram is included that makes replacing an old unit fairly easy.

Can't say for certain about this particular ballast, but my experience with other fluorescent fixtures is that F34 bulbs will work in place of F40 bulbs. Just be sure you are using T12 (1-1/2" diameter) bulbs and not a T8.

If you have wiring there, it is no problem. I installed three of these in series to replace two flourescent fixtures. Onehad a bad ballast and would only half light. I also do not like disposing of 40 watt tubes. I put in LED lamps that draw8 watts apiece so 96 watts total versus 4 times 40 or 160 watts. They are also much brighter. If you have wires on either sideof the mirror, or you can get the wiring there somehow, then you can install these fixtures.Steve Jahn

This bulb will not work with an electronic ballast, only a magnetic HPS. This is a conversion bulb from HPS to MH.

Yes any digital ballast should. This kit came with the option to get a MH with it if I wanted. The HPS bulb that came with the kit seems in great condition but I am still going to buy a bulb from a third party company that is known for a quality bulbs. ( I would never start a grow without a replacement bulb)

I believe you can. It uses a common Mogul socket which should work with a higher wattage bulb and since the ballast is built in to the bulb, this would not be an issue. If you are still in doubt, I would ask a electrician but I don't foresee any problems.

I think you can, i use it in a Lumatek Dimmable Ballast and it works fine, but i won't recommend to use it in less than 100%, it would consume the same power and will short the lifespan of the bulb.
800571
Yes ,i did it just worked fine. my ballast is for 600Wthe bulb works in 100% 75% and 50%!

the reason for the ballast is to convert DC into AC. So if you're replacing one, as long as it's for a 35w hid bulb, it'll work perfectly.

Yes, you should be able to. The sticker on the lamp says "100 watt maximum". I have a 13w CFL bulb in mine, and it works just fine.

No restrictions... This bulb fit right into our existing socket and worked with the dimmer switch we already had. I imagine it would be just the same for you!

This unit is only rated for 100 watts and I doubt that your metal halide bulb plus its ballast is less than 100. I wouldn't attempt it.

No, it will actually decrease the life span of the bulb. When the bulb is not used at the recommended wattage, ot also does not put out the full spectrum that the bulb is rated at.If you intend to only run the bulb at 50%, i would recommend just using a 400 watt bulb with your 600 watt ballast.

yes just dont put in higer watt bulb lower is ok. ballast works both mhl and hps
2268818
Yes it will work...All ballasts are the same set up ...just different wattage

Yes. The socket accepts 400, 600 and 1000 watt bulbs; the cord is a standard staggered 3-plug fitting all ballasts. Excellent quality for low price.
