I just bought a "Cool Tube" from Hydro Farms and WOW does it make a huge difference. It lowered my room temp by 10 degrees even after i moved the light 1.5 feet closer to my plants!

I do have a 135 cfm blower attached to it because that is the point of the cool tube.



My question is
My old light and ballast could handle both a HPS and MH bulb without the use of a switch or anything.. its an old shitty ballast.

With the cool tube installed, I can only run an HPS bulb.... I know I need a new ballast. Any recommendations? My bulbs are 400w.

I've heard lumateks are efficient and quiet, but can they handle HPS and MH?? Also can they be hand wired?

If a Lumatek is the best option I will buy one but I'd like to order from my local shop because he ships to me for free

I just dont want to get a ballast and not be able to wire it into my Cool Tube.
