The Ring Wall Sconce from CTO Lighting draws from the chiaroscuro principle, using stacked cylindrical rings arranged in a vertical column to play deliberate contrast between lit and unlit surfaces. Light emanates from within each tier, carving out depth between the rings and producing a sculptural effect that is as much about shadow as illumination. The brushed metal finish adds to the tonal richness of the piece, and the fixture is fully dimmable.
