One thing I'm really curious about, and I think would be very helpful here, is what the PAR/PUR numbers are for these lights when run at real world intensities. Dana your test was done a max intensity. However, a hobbyists will not be running at Max. Most are running a similar to AB+ with white and red/green at 25% with both blue and UV at 100%. Based on my Acro growth (or lack of), I'd say, running these at this program, which gives a nice visual spectrum, gives off barely enough PAR to support Acropora. What do you think?
