They'd have to be dimmed almost off at first and the corals right underneath would really take a beating I think. (I talked about 100w emitters with my LED buddy & he is of the same opinion that they'd be too powerful for our application).

Lots of people thought I was a little crazy going with 10 watters and now they're going with 100w emitters?

I would also ask the manufacturer what kind of warranty is on those since they are well over $100 each. At least with the 3 to 10w, you're looking at only a few dollars per, so if one burns out early, it doesn't hurt.

According to the thread, they recommend one 100w emitter per 2' x 2' area. For 10w emitters, I use roughly 7 so 70w at full power. The advantage is that if one of mine burns out, the light from neighbouring emitters covers for it. With these 100w emitters, using only 3 over a 6' x 2' tank, if one burns out, a third of my tank is dark.

Just something to think about. With less than 20 out of the needed 50 emitters ordered, I doubt that this gb will actually take place anyways.

Does anybody have a link to a reef tank that is actually using 100w emitters? I think hearing someone's personal experience with using 100w emitters over their corals will be the best info for this new technology.

What kind of PAR where you getting with the 10w emitters. I find 50w multichips are not bright enough for most tanks and I can't see 10w chips working for even a nano tank. The bleaching was probably due to spectrum (quality) not PAR (intensity).
