Anybody have these? Looking to upgrade to LEDs. Was wondering if anybody had these fixtures and if you're happy with them. Mostly want to keep sps. The tank is 2 feet deep. Would the two fixtures have enough power or would I be limited to keeping sps only in the top half, in your opinion? I'm just worried as in Feng's showtank, he gets amazing color out of his corals, but does have one fixture for every foot of tank length. Thanks.
