Hot damn! That looks awesome (and I did see this before you posted the link in the TOTM quarterly thread
).
I love that you've tried all those lighting systems. When I first started it was with compact fluorescent, then t5 (tank is 12x12x12, 7.5gal or so) then I talked to Jeff at J&L and he figured LED wasn't worth it. Now the T5 setup is TU and they don't sell bulbs for the compact fluorescent setup anymore (can't find them) so I'm thinking of going to LED anyways. Wasn't planning on doing a Kessil but they seem to be the best bang for your buck. Did you find the flat rack LED system (4th pic down) ok? Thats the one I was looking at because it seemed the least costly but now I'm thinking maybe kessil or whatever is available to me more locally so I can see it before I buy it (I'm picky about color too).
