I have Radion G3 Pro(4) and G2(2) over my tank 72X36 30H 1 inch glass. How many gallons is that? The water just come to about 1 inch from to very top of the aquarium.
I run the light start at 5:30-7:30 AM increase from 0-100% then at 7:00-9:00 PM the light go from 100% to 0%. Moon light on. From 7:30 AM to 7:00 PM the par at the Magnifica measured at 600-630. He have not move since I put him there. Seem very happy. I like the white color of the Radion at 100%. As it dim down the color change very slightly but not blue or anything like that. Moon light is really neat. Blueish that wax and wane per the Lunar cycle.
I kike the color of the tank, especially on my top down shots. The corals and anemone colors is really bright. My glue Haddoni's color is especially nice as the colors of my Petco Gigantea and my Purple Magnifica. Below are the top down color of my anemone when the light is at 100%
