I'm trying to build a light hanger for my new aquarium whose dimensions aren't compatible with the light bracket hanger things commercially available. I suppose I could go the EMT tubing route but I wonder if there are any local or online sources for bent, powder coated steel akin to the Current light hangers? I've found this website, but it looks like they only have straight lengths: http://www.eztube.com/steel_tube/steel_tube.html.
