I thought it was pretty interesting when looking at WWC's display tanks that the number of fixtures was less and the height was higher than I would expect on such amazing SPS tanks. I believe I have read that their tanks don't see more than like... 350 PAR at the surface of the water?
This brings me to my current situation. I'm used to running 350+ PAR on my systems with T5. I've also got a new system running that is LED only with radion G3 pro fixtures and their diffusers. The tank is a 150 DD (36x36x27). I have the lights a good 15"+ above the water. I'm running three fixtures right in a row in the center of the aquarium and seeing like 250 PAR at the top of my rockwork. At first I was concerned that this wasn't going to be enough, but as I said, the WWC numbers and method has me wondering.
I believe I've also head that vivid runs relatively low PAR with these fixtures as well.
