They say there is a good deal of change with cmh because the spectrum is based on the exact temp the gas burns at. I guess even air cooling it affects the spectrum and even if its in a vertical or horizontal hood. I use a 315w for veg and I love it its a cheap horizontal 3k phillips but the spectrum seems fine for being horizontal.Is there any degradation of the spectrum when dimmed or over driven?
