None of my Favias, Trachyphyllia, Symphyllia, and Lobophyllias like much light. I have them all on the sand partially shaded by other corals or off to the side out of the direct light of the halides. My lights are 250w DE 20K with electronic ballasts, so they don't put out a huge amount of PAR either.
