Kwic Wall & Ceiling LightKwic, designed by Serge and Robert Cornelissen, is a contemporary light fitting suitable for installation on ceiling or wall surfaces. A semi spherical blown glass diffuser contains an integrated LED light source and overlaps in a decentralized position with a circular painted aluminium disk. Kwic embues a space with a powerful light which radiates from the opaline white diffuser, and a delicate glow that filters through the back of the frame.
