Rapid LED Build

[MattM3]

Got about everything put together except for the LEDS. I've been trying to figure out how to arrange the LEDS on two 6" x 20" heat sinks from RapidLed.com. Here is what I have come up with. Any comments or suggestions are appreciated. Thanks!

Too many variables to consider. Your tank size, height of led off water, and degree optics you are using is a start.

My 6*20 heatsink from rapid only held 4 rows of 13 LEDs at an inch of spacing for a total of 52 but I used only 49 total... That layout is gonna be really blue!
