Success with LED and SPS

[chatyak]

I haven't read the entire thread - but do you have a PAR meter? Especially if the colors are in the blues on the LEDs... the amount of PAR given off by LED's is very strong on some models and under-rated on the blue colors- so much so that it burns corals. Perhaps the browning is this too?

LED's may looks dimmer to the human eye - but not a PAR meter. Thought I would give that input..
