Yeah, gonna be quite a few LEDs, but the nice thing about wiring this way, every line is broken up into three sets of six LEDs, (i.e.- each line is made up of 6 Royal Blue, 6 Cool White, and 6 Blue), and with each set of six dimmed separately I can not only adjust the brightness and slowly fade the "sun" across the "sky", but I can also adjust the color temperature throughout the artificial day (i.e.- the "golden hours", as photographers know, at the start and end of the day), as well. Plus it will give me more flexibility with programming "clouds", "storms", etc. It's not only going to take me quite some time to build, but to program as well, but once it's all done it should be pretty sweet, and something that I haven't really seen anyone do yet.

Thanks for the compliments on the plan so far, guys, but I can't really take all the credit. I liked the AI Sol Blue so much that I'm basically stealing their design, as far as color balance, optics, etc. I'll be using the same LEDs they use, in the same ratio, the only difference being that I'll use 60 degree optics throughout. That way if I angle in the two side pieces 30 degrees my coverage should drop straight down along the edge of the tank without wasting too much light as spillage outside the tank, yet have good even coverage throughout the tank itself. Should make for some good traveling shadows throughout the artificial day, too.

Can anyone think of anything I've missed so far? Any suggestions for changes/improvements?
