Thanks for all the replies! I have a Cree 60W LED over the tank right now but it has very little spread even though it is 16" long with lights edge to edge. Light fall off just 2 inches on either side of the fixture is pretty drastic. I have 2 AI Sol blues on another tank that I will be able to try out when the tank is getting shut down but I want to stick with just a single fixture and I don't think a single Sol will cover the 30" spread to my liking. The Vega is supposed to have much better coverage than the Sol as does the Radion. I also had a welder at work do up a light stand that is 18" above the tank rim so that right now is my limiting height factor. So the plan is to sell the 2 Sol's and controller and buy just a single light fixture when the time comes.
