This is true and I am even thinking of raising my lights to 22" off the water from 18" and trying a long photoperiod to see how that works. The light should be less intense but longer. The reason is that I can't keep LPS or even some sps in the middle of my tank, even on the bottom. They don't do well except in the shade. Birdsnest literally have to be out of direct light or they start to fade fast. I have also noticed one of my torts in not too happy about half way up directly under one of the lights but if I move it down to the bottom, its fine. Problem is, I don't want it down on the bottom.
