I just posted this in my build thread but thought I would share here as well. A buddy of mine (thanks Tony) that had access to a PAR meter came over last night to take some measurements and all I can say is 'Wow'! I am totally sold on Reeflux bulbs.

These measurements were taken under 3 x 250W Reeflux 20Ks (with Lumen Bright Mini reflectors), 2 x 60" VHO Super Actinics and 2 x 60" VHO 454 Blue Plus bulbs. All the bulbs are exactly 7 weeks old. Values were rounded to the nearest 10.

Tank Dimensions are 72"L x 36"W x 27"H. Bulbs are mounted approximately 16" over the water surface.

Yep, those things are beasts under LB's with the coralvue ballast. I have a very similar setup :D Wiz ;)

It was an Apogee quantum meter. Not sure of the model number.

Wow! Impressive PAR!! I'm curious, do you know what the PAR difference is between the Reeflux 20k and the Radium 20k?

Is that including the VHOs or is that the halides alone? Nice aquascape! Great sig too!

Unfortunately, I don't. The only other bulbs I had on hand to test were 1yr old spent XM's on my frag tank. They were putting out 56. Ironically, the 80W of NO bulbs on my fuge were putting out 20-25!
