I've heard that they are pretty good. I'm using the Coralife lunar aqualight and am very satisfied with that one as well. The only thing I don't like about the Coralife is that the fans only run when the daylights are on. I wish it would run for the actinics too.
I was going to buy a Satelite package, but found out I would have to change the light bulbs for my reef setup. So I bought my Orbit fixture 4x65watt that came with the correct bulbs and the legs.
I have owned several orbit lights... i can reccomend them... however i do like the look and quality of the coralife lights... i have sold all my orbits and bought coralifes...
