I just built one for the Aquatic Life Hybrid fixture. I wasn't happy with the way the fixture was hung so on my vacation last week I took some time to build a light box to place the fixture in and suspend it from the ceiling. I put a power strip in the box to keep all the wiring for the lights together inside and not have them hanging off the back, the only wire hanging in the back now is the power strip cord. The box was made with 1 x 10 boards and 1 x 3 for the molding with 1 x2 strips inside the box to support the fixture. Very happy with the way it came out and much cleaner looking with out all the wires hanging in the back.
Only thing left to do is paint the patched holes and hang the wall clock over the tank.
