Ok, so to be clear it was a tank of mostly soft corals, LPS and anemone's that had LED's on it for 3 months. I'll have to take your word on the great growth with what was in the tank. It seems a little premature to claim anything on a tank that crashed and currently has nothing in it, wouldn't you agree?
All of lighting you are recommending on the Chinese LED thread is coming from a tank that has nothing in it and nothing to show that the lighting you are recommending is growing anything and doesn't even have the Chinese LED's in it, you replaced them all to improve the fixture. Seems odd to me to be telling people to use something you aren't even using and haven't used with success. Maybe I am looking at it wrong though. While I like what you have done with the fixture and believe it will work great, it hasn't actually worked great yet.
Soft corals, LPS, SPS, anemones... It was a mixed tank, and will be mixed again. 3 years of MH/T5, 3 months of LED. I did not lose any coral from the leds, and there were no color shifts in that. 3 months with growth shows a tank previously grown with MH is completely sustainable with growth using leds, even the cw:rb chinese ones used there. You can take my word or not, the fact is, it grew the coral, and I did not regret the switch. I would have loved the tank to not have needed to be torn down as well, but such is life.
The DIY fixture and re-started tank will be a great way to document things. It has a few pieces 3 months old, and each have grown a bit. As more and more gets added, I can show it a little better. Its going to take a long time, but nothing has made me wish to switch back. If something did, I would switch back in a heartbeat.
I would love to start throwing more SPS in aside from the two pieces in now, but transferring the bioload of fish over + Pukani leaching made it very risky (and dumb) to load up on them until the water parameters were less volatile. I'm not even a fan of SPS dominated tanks, and there are quite a few SPS snobs out there who scoff at any tank that isn't one. Some people like myself just aren't into it, or are on a budget. Leds have been a blessing for that group. Soon enough, I'll start adding and documenting more. A little data is better than no data.
It seems that more people are willing to completely dismiss leds (I'm not saying you are), than to agree that they are a viable alternative that is more experimental as of now. If my 120 gallon tank wasn't freshwater and was an established SPS tank instead, sure I'd be more inclined to stay with MH/T5 myself, or go LED with T5s than to risk a full switch until lots of established tanks are shown with them. Leds with T5 would probably look outstanding over it. It wasn't until this past year that leds started to really come into their own.
