i have both the double bright and the new reef capable one. i got them to test on low light tanks. they are ok for that use, however, the whites are 10k but tend to wash out colors, and the blue are plain useless for planted tanks. you get major spot light effects with the reef capable one as well. it would be an easy engineering fix to modify the fixture with combo 10k and 6.5k whites for fw sales.
I would love to try CA led fixtures if they are designed for fw planted tanks. all the mass produced fixtures i have seen so far are salty oriented and not very good for our market (not a DIY guy, so making my own is out of the question). i have many of their t5ho fixtures so the quality and customer service is there. cant wait.
