Then planning to put 1 Kessil A150W 7'' from a crocea clam at the top of the tank

any opinions or experience would be appreciated!
 
At 50w per chip, that is alot of concentrated light. Using smaller Leds, you can distribute the light to have a more uniform spread. I've seen where lights have had too narrow of a spread causes spotlight effect which will stress/bleach corals. By all means experiment but be aware of possible issues and watch for them.
