These industrial sconces hang off the wall and plug in, hence the name "pin up", instead of hardwiring into a junction box. Cages are heavy duty and powder coated. On/off switches 3' below the bottom of the sconce on the cord. Here shown with a 5" diameter bulb but these gear sconces can take any medium (standard) base bulb. Cage is 10" wide while gear against the wall is over 7" wide. They project 16" and the height without a bulb is 12".
