I've actually had a thought on the edge lighting problem for a while in the original hood. Wouldn't it work to angle the leds towards the eges Like from the far left side of the hood, angle the led toward the right side of the tank, and vice versa like the shape of a parabolic mirror? This would allow you to position 4-5 LEDs in a parabolic configuration inside that small square and still cover the entire subsrate evenly. I'm sure i culd figure the math out for it if i had exact dimensions, just a little calculus.
