none of the 150w ballasts list the xm 15k as the highest PAR bulb.
I was looking at the list for the 400w magnetic ballasts. It is different than the 150w list. As I said, the XM 15k is the highest PAR bulb of the 15k options for my ballast. There are a few 10K options with higher par than my current 20k XMs but those 10k are the only options higher in PAR. The 15k is lower and I have since started looking at other ballast/bulb options.
