I’m running 4 Radion G3 Pros across a 6 ft tank (lights are run width of tank instead of length) and I have no issues with coverage. I’m running the lights at 50% intensity also using the Coral Lab SPS AB+ except I tweaked the whites a bit so my tank isn’t heavily blue for viewing pleasure. Everything is happy and no bleaching at the settings. I have some acros toward the bottom and they are still branching out and happy.
