LED's really pack a WALLUP and they do NOT look bright to our eye. It is very misleading, you can cook corals under what looks like very little light. I have been doing as much research as I can with LEDs and really the only reliable way to gauge output is a PAR meter, and even it reads LED 20-30% less then what is actually there.
I feel like they are not getting enough light but I could be wrong. The SPS's are the only ones strugling and they generaly require the most light, but I do agree w/ you poseidon that a PAR meter would be the way to go b/c then I would know for sure. Problem is I don't have a PAR meter and Ive spent too much on the LED's already.
