Uncompromising. Different. Evolutionary.

The SONIS from RZB sets new standards and (r)evolutionises the world of recessed ceiling luminaires with its innovative Alea optical system. The square reflector elements are combined to form a reduced, linear structure. The non-yellowing, opal diffuser reduces direct glare, ensures excellent light quality and protects the highly efficient LEDs. Thanks to the dark light effect, the SONIS has an impressively discreet presence and produces glare-free light to work by, which conforms to standards. With its matt white housing, it inconspicuously blends in with all light-coloured ceilings. Its cost efficiency and the revolutionary Alea optical system make the SONIS an attractive alternative to popular surface lighting.
