I used 860 watt cmhs for a while. Nice spectrum, not much punch though. Probably the magnetic ballast required to fire them is my theory on poor performance, though I have no idea if that's fact.

Honestly? The owner had already bought them when I was hired... That being said I do like the simplicity and the light spread off of them. All I was really concerned about was that they were 315s at the time I was hired to run the op.
