So, doing some math I stole from another site, I've come to the conclusion to light my tank with 3w LED's from CREE, I would need.. 144 of them?

Is this even possible?

At 6 bucks a pop, is LED lighting still out of reach of your average, non-lottery-winning aquarist?

That's a row every 3" and an LED every 2" per row.

I REALLY would like to use LED's to augment my VHOs, but at that cost, it might be better to get a T5 retrofit kit and pop that in.

Anyone have any input? Less coverage maybe? Use inexpensive LEDs? Pray to the LED gods? I really am open to any suggestions.
