the sun is pretty hot and that is what we are trying to duplicate with our lighting. that being said, corals can be found down quite far in the ocean and grow great because of their specific lighting requirements. for your SPS and nems, they will be great. LPS should be fine half way down on the rocks. soft corals will need to be on the bottom of the tank and mushrooms will need to be shaded tho. they will shrivel up and die with that much light
