i have an ai sol blue over my 55 gal. "fuge"... kinda over kill.....you should look into wingo's cree brick. comparable to ai but come with non-programmable manual dimmers....only $200(got it on special sale....~$230 now?).
i got it for my 15 gal. office nano tank that has a set of diy leds......haven't swap it out yet so no comparison comment at the moment.
