I'm in the process of shopping for a new vanity light and have run into a problem. My old light was a 2ft bar with light bulbs. When removed, we found that the box and wires are located to the far right of the light bar and can't be moved to the middle because there are pipes in the way. From what I can tell, most new fixtures have a standard mounting strap in the center of the fixture. I need a strap that moves to the right. Any ideas on where to find this?
