I had believed that corals exhibiting orange through red fluorescence would be from deeper waters and hence require less light. See the graph - No sign of photosaturation at PAR of 500 and above. I have a lot to learn.

Interesting. Could it be that they don't have the ability to shut down in photoinhibition? Possibility because pigment in the zooxanthellae?

Interesting, mine grows faster in the shaded areas then the highly illuminated zones.
