"To a hammer, everything looks like a nail:" If you like growing sticks, then Kessil may not be the best first choice. If you have a mixed reef tank, they look really darn good because of the intensity drop-off from center to edge, and at each 6" declination. I have to keep my Kessils turned down to ~50% to avoid over lighting my mid and bottom areas of the tank. I run three AP700s in a horizontal orientation on my 300 gallon, spaced 24" on-center.
Someday I'll need to replace these lights and I'll look at the needs of my tank and the type of corals I'm growing to make a decision. In that respect, the information provided by BRS's study is extremely useful, because no one else I've found is giving me (FOR FREE) such amazingly thorough information.
I guess you could argue that it's biased information because they only provided feedback for some 15-ish brands, in 2-5 combinations of each brand; I guess you could say I'm also biased because I like Reef2reef more than Reddit...
