I am starting up a new 54x30x24” reef tank. Since it is an oddball size (based on wall constraints), I am seeking guidance on the optimal # and orientation of Mitras 7206 lights.

2 - Parallel with length - possibly not reaching the back?
2 - Perpendicular to length, with less on each end?
Hopefully the answer is not 3… $$$

Also, if I were to install 2 Parallel with the length, if I set them closer together to avoid the overspill on the edges, would that cause issues with to much light right in the center? -or can you control segment of the LEDs to compensate for the overlap?

May be dumb questions, but I want to set this up right from the beginning as I am designing custom light mounts with 8020.net extruded bars, so it makes a difference on parallel vs. perpendicular as well as 2 versus 3.

Input would be much appreciated.
