Rough'ed a bath a while back, got called for finish with customer provided lighting. The customer wanted excact placement of some vanity lighting. (All of which landed on stud work... So 3 3/0 pancakes.) So today, I go and get the lights out of the box, and said to myself, "Wow, that's a small canopy? How does that mount? That can't be legal. It mounts to a 1 gang box?"
Built for the exeption, at 5 1/2 lbs!

I am seeing those coming from high end lighting stores. I had one where I roughed in a 4" octagon then came back for the finish. They had purchased a bar fixture that was too skinny to cover the box, needed a one gang mounted sideways. There is no way that fixture weighed less than six pounds, it was four feet long with three lamps with heavy glass shades. I mounted it low on the octagon so the part that wasn't covered was at the top where it couldn't be seen behind the center shade, then made up a metal cover for the gap. I told them it was a non standard fixture and it wouldn't be safe or legal to hang from a one gang device box. It was made in England. It seems like customer purchased lighting is always throws a wrench in the works. Brian
SolarPowered, The fixture was set up with 50Watt 120V halogens. I didn't even think about the 240 volts in Europe, the fixture had to be set up for export I guess, or maybe it was done here. The customer said the light took 6 weeks to get.
