Story
Direct and reflected light
The circular luminaire combines softly diffused, glare-free light directed downwards with reflected indirect light from its curved upper rings. A large angled reflector encircles the diffuser and lowers the contrast at the edge, and the top reflector is curved to spread uplight at a broad angle.
Four rings of light
A coloured outer shade surrounds the reflector and creates an interreflection of light, which gives a glow on the outside of the top and bottom reflectors. Seen as a whole, the fixture has four rings of light around the central diffuser.
