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.

I think the fan thing is completely blown out of proportion. The fan is in its own housing and if you were to get spray on it, you'd just wipe it of. If fine droplets would be just as much of an issue with side mounted fans. I'm most likely to splash water when I'm adding new water after a change. My radions had zero evidence of sucking in salt water.

Radions won't punch as deep as Ai's. Even at 24", the radions will be less par.
