Wallwashing for high rooms
Multi-storey spaces pose specific lighting challenges. Previously, wallwashers had to be mounted in very high-ceilinged rooms at a disproportionately great distance from the wall; however, the ideal position for the recently developed Atrium double-focus wallwashers is now at a distance of only one fifth of the height of the room.

Also suitable for sloping ceilings
As variants with a pivot angle of up to 30°, double focus downlights can also be mounted in sloping ceilings.
