I have 3 Reefi’s with 120 degree lenses along with a 4 bulb hybrid T5 over my IM 200EXT and love the combo. You could probably get away with 3 lights in the beginning and as the SPS grow in add a 4th to reduce shadowing. I bought some 80/20 rails and mounted them directly to the stand and hung the lights off of that.I guess how is the app vs each other, can they be controlled on the road away from home?
Can you hang a light bar on either with the mounting options they offer? I think performance wise they are probably pretty equal as far as performance, par, coral growth, and looks go.
