Thanks!
Those photo's were not very "shopped". What you see in the pics is what it looked like under the LEDs.
Originally I had 12 Cool White and 12 Royal Blues. It looked like crap. But after much research I finally settled on:
6 Neutral White
2 Cool White
2 Blue
14 Royal Blue
They are all XR-Es.
IMO the switch from using too many Cool Whites to fewer Neutrals made a huge difference. And keeping a couple Cools in the mix seemed to help some colors. And the 2 plain old Blues helps a lot. Not so much that the tank ever looks like a bottle of Windex. I guess the trick is knowing that a little goes a long way.
The LED being that standard multiple row of evenly spaced (2" apart) means that I do get the inevitable color banding, especially in shadows. But it doesn't really bother me.
IMO overall there is a small loss of some color over my old MH Radium + Actinics. But that is more than offset by the subtle fluorescing of many of the corals, appearing much brighter in an overall color balance that is dramatically similar to the Radium. Frankly I was shocked at how good it looked when I finally set up the fixture with the new LED mix. Never for a minute did I think I had moved backward esthetically. A little different, and maybe a little better overall. But definitely not worse.
