That's "not true" for most bulbs actually. XM's are the only widely used halide that has higher PAR on a standard mag. than an e-ballast.
The ReefLux's he was looking at run with at least 20%+ more PAR than on a mag.
I was speaking specifically about DE bulbs, and I had a look on Sanjays website and all three bulbs I looked at, BLV, Giesmann, AB all put out more par running on magnetic HQI ballasts than on e-ballasts.
