This is a simple spacer/bracket for mounting the Lindby Renata Concrete Wall Lamp (9613058) 10 mm off the wall, while allowing to route the cable straight down.

I bought three of these lamps, not realizing they were meant for in-the-wall cables, and didn't have any way to route the cable down towards the floor. This spacer, pushing the lamps 10 mm off the wall, while allowing for a cable, is my solution to the problem.

Simply mount the lamp to the wall how you normally would, following the included instructions, but put this spacer between the original mounting bracket and the wall.
