Individual elements on spacers
This mounting method only works when the building allows all the individual cables (one per element) to be brought together behind the wall. Typically that's only the case with drywall or hollow walls, or on exhibition stands.
Where it's possible, it's the most elegant option: the elements float completely free, with no substructure interrupting the light. And thanks to the proven click mounting, they're just as easy to take down and reposition later. The wall distance is set so the light corona sits perfectly around the cut-out.
