I already installed all 70 degree optics on my AI fixtures so that I could crank them up higher. My blues hit 100% at different times throughout the day but my whites never get above 25%.
With the fan on the bottom of the fixture I'd never mount my (if I bought them) Radions close to the water. They'd be 11 inches above the water line just like my AI units.
