I have two A160 plus the hybrid t5 24" from Aquatic Life. My tank is 36x18x12 however its an AIO and that takes up about 4 inches of length so my tank is really 32 x 18 x 12.
I made a custom mounting instead of using the wires they give you. Also, Aquatic Life only comes with the A360 mount, they are making the A160 and it should be out soon™.
I do need to clean some of those wires up.
Edit: I will post my setting tonight
