Ceiling plafonniere produced by the German technical lighting specialist RZB Leuchten. Known for their durability and high-quality optics, RZB fixtures from this era often feature heavy, architectural glass. This model is defined by its thick, textured "ice glass" diffuser, which features a geometric, diamond-cut pattern. The fixture is mounted on a sturdy black bakelite base. The original manufacturer's foil label (Model 30552.80) remains intact on the base. The glass diffuser is in excellent vintage condition with no chips, cracks, or noticeable scratches. The original restrictive socket and wiring have been professionally redone to accommodate a standard E27 light bulb.
