no where in that graph does it say how much light is put out, only how much of the output is usable.. it is a very nice marketing ploy though..

Doesn't this quote from that link address the PAR issue?

"Using the data shown in Figures 2 and 4, plus standardized surface area, the 75-watt Solaris produced 89.4% of the PAR generated by the 250-watt XM 20,000K lamp.

This equates to totalized PAR (µmol·sec) over a normalized surface area of 113 µmol·sec per watt for the Solaris, and 38 µmol·m²·sec per watt for the metal halide lamp."

It sounds to me like the 75w Solaris produces more PAR per watt, but less PAR in total. But not substantially less... 89.4% of the MH PAR.
