I'm not thrilled with the radions at all. I got the "blue" version, but they are waaaaay too white for my liking. I revamped the remaining ~80 LEDs with new bulbs when I did it, and I really cranked up the UV potential, but I can't run them more than ~2 hours a day or I bleach the corals almost white. Normally that would be fine, but the light light corals only look good under royal blues, and the radions never really get to "just blue", at least not as far as I found when I programmed them. So if I had just the radions, I'd have a pretty boring looking tank. At ~4pm I kill the radions and run T5s and just the leds, and the corals look fantastic. The more water changes, the better the colour, but the growth also gets out of control. I have a millie colony the size of a basketball already...anyway, I think if I was to do it again, and $ was no concern, I'd run 2-3 radions from 10am-2pm, and then run 120 royal blues with just a few UVs (I think I found 370nm units) until midnight. If we move and I do set up another tank, that will be the way I would go, but to use the radions as my only light source...no, not a chance. Thing is, I also want completely different colours than normal. The Orange passion I got from bigshow was a hairy dark orange bit when I got it. Very nice looking, but I wanted to see what I could do with it. In my tank it is mild PE, the coral is bright yellow with extremely blue tips. Just a totally different (but awesome) look. Maybe just me, but I honestly don't care what my tank looks like, as long as the corals are interesting. I'm so far past the whole fishtank as a centerpiece, I honestly would likely be fine with a shallow reef down-from-the-top tank, just filled with damsels or something for bio load. sorry, really went off on a tangent there.
