High Bay Industrial Lights

[Tsuto]

Ok here's a question for people: Browsing craigslist I came across a local guy selling 4 high-bay 400w MH industrial lights for $200 and thought it might be a good deal for upgrading my lighting as I expand my setup some. Would these be suitable for installation in my grow room ceiling?

I guess the issue I see is that if I had them actually mounted on the ceiling they would provide plenty of light but wouldn't be adjustable in height unless I thought of a way to hang them. I guess with the proper wiring I could have them hanging from chains on a hook on the ceiling and be able to adjust them that way

Ok thanks guys. I may get the lights and see about setting them up before I start my next cycle of vegging

IMO, $200 is far too much to pay for that. You can buy a 400W with a digi ballast/cool tube/HPS bulb for under $150 on Amazon. The same thing in a 600W is under $200.

Its 4 though so $50 each. I should have specified they were being sold as a lot

just watch out for the headroom they need buddy... need some tall ceilings or maybe you can re-rig them by moving the ballast...

Yep I would most likely do the remote ballast setup others linked earlier

I like this conversion guide, of course using US style plugs and things - hxxp://cannaversity.com/cannaversity/article.php?id=046

Once I have the ballasts set up maybe I can follow Hemp Goddess's DIY cooltube guide and make two of them out of the 4 lights

sorry but the 400 are to fat to fit in a bake around..

I have one of those high bay lights and really do not like it or use it. I recommend T5s over MH for vegging, even at $50 a pop. I get about the same veggy growth from 216W of T5 as I did from 400W of MH. Of course, this translates to less electricity usage and far less heat. HTG suppy has some decent prices on their brand and sometimes you can find great things on E-Bay.

Yeah I was looking at a 4 bulb T5 fixture on Amazon that would fit my closet grow area perfectly that I may go with. I'm probably going to limit things to 2-4 plants at a time and fill about a 6 square foot area.

If you'd like to look at my "artist's rendering" below I would probably set it up like that. A 2 ft, 4 Bulb T5 HO fixture would fit perfectly in the corner of the closet where I could hang it over a table. Then section off that area of the closet with mylar mounted on a shower curtain rod for easy access.

Currently I'm using a 100w MH flood light so anything will be better! lol

Use em...love em. $50 is a great buy. You can get a 5k kelvin 400w MH at home depot for $20, but I would spend the extra few bucks and get a 6500 Kelvin bulb or better online. (make sure it's a universal position metal halide)
Ditch the dome and buy or make a batwing reflector or air cooled hood. Add an extension to the socket. Add a plug and you are rockin and rolling.
build the other three same way sell em craigslist or ebay for $125/pc (more for air-cooled like another $70 at least.) make your money back plus money for more stuff.

Yea if you use it ditch the dome, Its too much like a spot light too low, there ment for 18' and over ceilings.

And if you dont have a HPS setup yet you can flower just fine with a MH, unlike a T5.

given this would this be a good grow light it looks kinda old but 50 bucks is a hella deal and i could add 400 watts to my grow

Make sure you can deal with the heat.
