I keep my Fox Flame under a lot of light... like so much that your kessils cannot probably get there. It it an easy coral to grow and will do well in either condition. I would not worry about this one too much as long as you are getting it 250-275+ PAR all the way up to 750+.
The Pink Floyd will do well under any conditions, but the better yellow and white contrast comes in medium light, for me. This is in the 350 PAR range. It will do OK with more light, or slightly less, but the colors are not as good, IMO.
Do you have access to a PAR meter?
