I could not tell you if you could actually grow them on the sand bed though. I had VHO lighting and MH before. I would say your Radiums are going to have more punch than the Kessil. That being said, i do have the wide angle variety that spreads more than punches down. I would think you would need 3 of them to cover your tank but i can't speak for the A350 that doesn't go wide. I have two A350W lights covering my 48" tank perfect. I can't complain. I have them going 100 percent though. I never thought i would like that blue but it brings the colors out nice and my corals are loving the new LED's. I have had some for over 10 years and they adjusted great. The temp drop is incredible though. Nice cool water here for my Florida tank and the corals love it.The only thing i will say about them is the converter gives off some heat. I thought they would be warm but they are quite hot. You put that underneath your tank anyway so it shouldn't be a problem. I would go with 3 A350W but you would have to be the judge of that one. Hope this helps. Oh, my lights are 9.5 inches off the water also. My rock structure? I would have to say i have an sps about the size of a softball or better and its about 8 to 10 inches below the water. I'm guessing though. The higher you go with them, the more they angle out for better coverage. For the size of the lights, they are bright. I am impressed.

For all the reefers that are currently using the Kessil a350/a350w on their aquariums, can you please post pictures?

Explanations of your aquariums are nice and all, but it would really be more beneficial to see pictures of the coverage and corals.
