I have never had those lights. Also, there is a big difference in clam light between the different species.

Can you get any PAR readings on them? If they are anything like a Kessil, then they might struggle that deep anywhere outside of the 6" area RIGHT underneath the light.

Deresa or Squamosa might be OK if you can get 200 PAR. I would avoid Crocea and Maxima.
