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.
