Alright, I made a little diagram of what 10 LEDS will look like, how much overlap and how much spill over was going to occur.

i noticed that i should be moving the rows to 4 inches closer to each other, that'd give better spread laterally

the angles of the cones are only 20 degrees, I wanted to model how the bright spots will overlap. since the brightest light will only be in the first 20 degrees in a 40 degree optic.

you can see the 2 inches at each end where the tank isnt getting bright light. oh well

this is how the overall image looks.I changed how the LEDS are spread out on the bar, not every 6 inches but every 5.75 inches leaving 6.5inches on each end. that way more of the light is focused on the tank
