So here is a SketchUP model showing LED spacings.

Its 3.5" between LED and on the center, it is 4" spacing. This is because of the brace on the center of the tank.
I can really go with 3" spacing and then bigger spacing on the center, just worried that I might have a noticeable shadow spot on the center. Either way, we can always adjust it in the future.

I dont know if I mentioned it already that with the package, I bought 60 degree optical lenses. So I have been playing around with SketchUP or SU, to determine if my 3.5" distance will work with my tank which is a 75 gallon.

so here are some images showing the 60 degree lenses.

These are at 12" above the water line and 3 inches between strips.

Another view with the same configurations.

Here you can see the scope of the cone.
