I'm actually feeling a little underwhelmed at the showing of the Radions. I know they're more even, but they do seem to get blown out of the water in terms of PAR by a whole bunch of other fixtures. For nearly 800 bucks a pop, "is it going to be enough to grow clams on the sand bed (or anything else that I want) in a 24-26" deep tank?" shouldn't even be a question that needs answering with a months long experiments in fish stores and on reef blogs, it should have been obvious from the very first test some reefer did with their at-home meter. I was set on getting 6 of them for my tank until I saw people posting PAR numbers in the low 200s at 12 inches deep. I know people keep saying that might not be as important for LEDs, but we have to evaluate new information within our existing framework until a new framework exists, and according to what we've all been learning for the past several decades, those numbers are really not impressive.
*sigh*, more waiting while other people are the guinea pigs I guess.
