I've only ever had the 160w model. I think mine is at 18 or 19". Any closer and it's too hot.
It is not as bright as an incandescent of the same wattage, but I do not have any green or off color center. The color was more white than the powersun I went from, but definitely less white and less bright than the same size incandescent, which makes sense, because some of the power is going into uvb production that we can't see.
I'd definitely write them about the green center, though.
EDIT: how long had it been on when you checked the temp?
