It looks like a very good fixture, especially with the 420nm violets. I do not like, however, the 16k version, as royal blues should never be mixed with cool whites on the same string, as you will lose controllability. All in all, it is a good unit, and has the spectrum most of the competition lacks. What size is your tank?
