Which brand do you run on mh bulbs?

Have anyone ran a 20k by coralife mh bulb before? I am getting a deal on it, and thinking purchasing but there is a no return policy. Any input ill any appreciated.

Funny I JUST started using a couple of these very lamps on a tank I'm setting up, but I'm betting they are not very good. I got a deal on mine as well from a Petland that was closing down. I figured I'd give them a shot, but when it comes time to change them, Radium for sure.
