I ended up going with the Orphek PR-156 light for my aquarium. It was important to go with LED for the energy savings but I also wanted to make certain that I had a fixture that would stand the test of time. I think I went with the best choice. A lot of the decision was made on looking at the tanks posted on the net and seeing both lights in action. This pic shows what I am mainly talking about. I found it on a German forum. Didn't translate well but it's pretty self explanatory.
IMHO
1. There is a definite difference between the corals under the AI and the Orphek colorwise.
2. Stuff under Orphek has color and life, the AI stuff is dim and grayish/blue.
3. The AI lights appeared dim so I PM'd the owner and he told me that he had them at 100% and that's why he started looking, because he felt the AI were too dim. When he found Orphek he tried a few and has since switched entirely over.
