Hopefully I won't confuse you with this. I do not understand all of the science or technology behind this issue.

I have successfully kept Bubble Tipped Anenomes (BTA) under both MH and PC lighting. The question comes down to intensity or PAR ratings. What light and what intensity can be delivered to the animal at what depth?

350 watts of MH lighting is on my 80 gallon tank and my BTA kept partially hidden in an overhang with indirect lighting. I have 110 watts of PC lighting on my 20 gallon tank and the BTA is in indirect lighting on the side of my LR with a slight overhang. The BTA in my 80 gallon is approximately 20" from my MHs. The BTA in my 20 gallon is 12" from my PC lighting. I run 10,000K bulbs on both tanks, K = color, but the PAR or intensity must be relatively the same at the different depths. My 20 gallon long is much shallower than my 80 gallon.

Intensity is really the key. I hope this helps, but if I confused you we'll clarify for you.
