I'm running a 48" reefbrite on my 120. I have pictures, problem is that cameras do not take pictures of lights this far past 10K that look anything like the tank really looks. You really should check some out with your own eyes. All I can say is that the light is FANTASTIC, and IMO much nicer than the powerbrites. the powerbrites are very focused and these are very spread out.
If you are going to the frag swap you might get lucky and see if Johny or Brent has theirs with them
NOTE: I don't fully have a grasp on this - from what I gather our eyes process light and manipulate it into what we see. when you take a picture the camera doesn't always do the same thing - hence why pictures don't look like the real thing all the time.
