Here's the hanging light frame. I consider it a prototype - in a clean build or new setup I'd use nicer wire to hang it (rather than the cheapo chain) and make sure it was centered over the tanks.
The main reason for the construction was that the little legs that fit the light (a Coral Life 2x96w PC) aren't high enough for me to open the lid all the way for cleaning and such.
It's currently over a 45G tall and a 29 gal in an L shape under my stairs.
The first picture is from the original setup (about a year ago).
The second one is from the side.
The third one is with the light removed so you can see the "rails" that it's hanging from.
I put a strip of wood along the front and back to "space" the light away from the threaded eye bolts. The stock was 1/2" aluminum 'L' from Lowes. It cuts fairly easily with a hacksaw, and then I drilled the holes.
The smaller section is a small section of light diffuser with three LED moonlights sitting on top, for nighttime.
Hope this helps - steal any ideas you'd like, as long as you show us the results.
edit: It's actually 1" aluminum - I wanted a nice wide base for the light.
