Hers mine. I have them mounted to 2x4's. The wires go into the 2x4 and into the endcaps. Makes it look real neat and not cluttered. They are about 3in off the water.
Internal reflectors yes, but that much light bouncing around the inside canopy? I like what the reflectors do with my URI's bouncing it all down.
No hard facts for ya kip, just one of those I'm going to do it because it looks great things.

White will work well Ross, but I found much better look and growth from adding some aluminum roof flashing. It was 3 bucks for 40 feet. It polishes very easy and makes nice reflection into tank.
