I have already emailed Reef Brite to request any info that they have on PAR output. We do have a copy of the spectral output of the strips, but right now its a printed copy with a small graph.
As for PAR output, these strips are supposed to have double the PAR output of an ATI Blue Plus with reflectors, but as for actual numbers I dont have those on hand at this time. I dont suppose anyone here has a PAR meter?
Here is a link for the Reef Brites being used as a suplimentation on a large tank for you:

And here is another link to them in action on a deep tank with tons of halide lighting:
