Thanks a bunch for this post. My husband and I were a week away from buying a six foot odyssea light for around 500 dollars from aqua traders. The similar lights we've seen (marineland) run about 1400 dollars. (These are the combination lights). Now, after reading your post, and doing some extra research on both the seller and the manufacturer, we've decided not to go with this light. Unfortunately, that leaves us in a lurch, as we can't really afford the 1400 dollar light, and we've already got everything ready to go (including live rock and sand!) in our 180. I guess, though, that if you look on the bright side, at least we saved 500 dollars which can be used toward a better light.
