I'm not a lighting expert at all. All I can say is that it's shocking to see the huge variations in light levels under a given light when you run a par meter. Six inches to the left or right on a rockface of roughly the same height and you can see par swings of 80 or more. The sides and front and back similarly can fall way off.
At 3" off the water, you've probably got even more dramatic hot and dead spots. May well be sweet spots for various corals.... just that the human eye can't see it.
