Thanks.
I think the biggest difference with the LED's is the way the corals look now. The LED's are alot blue-er, so when they are on the corals look more colorful. I was using Iwasaki 15K MH bulbs are they are very white. When the actinics only are are, they look about the same. Growth is still good. Definitely no less, but probably no more either. I don't really think lighting is the biggest factor in coral growth, even tho it definitely does matter. I think flow, water quality and stable water parameters are key.
I've read stories in the past about bleaching, browning out, and corals dying after switching over to LEDs. I just wanted to see if you saw any of those same problems, glad to see someone with such an impressive collection of SPS not having any issues.
