He said u can use a cmh or hps bulb on it...that correct? Would u guys buy it for 50? Light ballast cooltube?

No. That light uses a mh ballast so you can only run cmh and mh on it. Cmh he bulbs suck. Which it comes with. You want a Philips bulbs.

The 315w cmh lights are the best and most efficient hid lights.
