Ballast Identification

[Merica_Mike]

I have this Digital Electronic Ballast For 400w HPS and MH lamps. I can't seem to find any pictures of it online or even what the brand is. I even searched the model number only to come up with slightly different versions of it. I have a couple questions if anyone on here is familiar with them I would greatly appreciate the help. Here's some pictures of the ballast itself. First question is what brand is it? I feel like it may be a cheaper one. And second if I want to run a MH in it do I need to get a conversion bulb it just a regular 400w MH?

400 watt MH. But why? Less effective use of juice than HPS.

I did not know that. But as I was looking at bulbs earlier today I did notice that the lumens were lower on the 400w mh bulbs than they were on hps, which I dont quite understand why. But I was thinking I'd put one in there with the idea of more white Kelvin temperature would help with vegetative growth. Now I'm not thinking that though.

I've stopped using MH except as an adjunct to HPS the last couple of weeks of flower. That just to increase THC. Supposedly.

I have also heard of that. I dont think it would really be worth it in my case though. But I do have mixed spectrum T8s on the side as a way of trying to supplement it in.

Just use your HPS all the way. I do everything from clones in cups under plants to vegging and flowering all with HPS. MH is useful to keep plants short and bushy but T5 does that and it's cheaper and cooler.

Will do thanks for the useful information!
