Welcome to RZB

We make light. We think 360°.

RZB Headquarters, Bamberg

As a lighting and luminaire multi-specialist, RZB Rudolf Zimmermann, Bamberg GmbH - RZB for short - has stood for intelligent lighting solutions "Made in Germany" for over 85 years.

As a diversified group of companies, we have a considerable vertical range of manufacture in Bamberg. Our sustainability activities, which have been recognised by EcoVadis and others, and our DIN-ISO 9001 certification illustrate the mentality of our company.

The focus of our internationally operating family business is on the development and production of indoor and outdoor luminaires, emergency luminaires and efficient lighting management systems. A new addition to the portfolio is the RZB Energy brand with a new, fully modular concept of luminaires with integrated charging functions. Proven light pedestals and bollards, which have so far defied wind and weather as pure outdoor lighting, have been hybridised and now offer architecturally appealing, modular charging options for electric cars in public and private areas.

Whether in industrial, office or shop applications, in private and public buildings, outdoors, on paths and squares - with 360° Lighting Competence we offer our customers lighting and services from a single source: from consultation and planning to financing and commissioning, service and maintenance to continuous monitoring and optimisation over the complete life cycle of the lighting installations.
