I have a 60" ATI Sunpower (8X80w) fixture - and I really love the fixture. However, I am missing that LED shimmer and pop. I know that the Reefbrite LED supplements are nice, as they are similar in look to the fixture and they just bolt on. That said, Im curious as to which one people are using. There are several different types of these fixtures, and since Im not looking for more PAR - I assume that I want to avoid the white or 50/50s. That leaves the BLUE or the UVA - which one are people using for supplementation? And - do you install the reefbrites on the front of the ATI fixture or on the back? Is there another set of LED strips that anyone recommends?
