Zahnmedizin Quartier 207, or “ZMQ207” for short, has moved from Berlin’s Friedrichstraße to new premises on Leipziger Straße. This relocation also marks the starting point for the development of a special luminaire inspired by the infinite mirror lights in the lift ceiling of the Lafayette building in Quartier 207.
TEASER-CLIP
COVERAGE
The new lighting concept for the ZMQ207 practice rooms follows a clear architectural objective: to create high-quality, precisely controllable light that meets all workplace and medical requirements while also impressing with its efficient and glare-free lighting effect.

SKILFUL INTEGRATION OF CLASSIC ELEMENTS INTO MODERN ARCHITECTURE
Using Barthelme PINO Grande luminaire profiles up to three metres long, combined with LED strips from the Barthelme LEDlight flex STANDARD series and the LEDlight flex Ultra High Efficiency series, luminaires were created for the entire practice.
While clearly referencing the classic fluorescent tube impressions from the Lafayette building, this precise reinterpretation of the luminaires consistently blends into the modern architecture of the new practice rooms. From a technical perspective, state-of-the-art efficiency and colour rendering values were required. A high CRI, in particular, is a fundamental lighting requirement in implantology.


UNIVERSAL USE OF THE LIGHTING SYSTEM
A key objective of the Merianos architectural office was to design the luminaires so that they could be used as universally as possible. Accordingly, the PINO Grande linear luminaires were planned for all areas of the practice — from adjustable, suspended versions in the treatment rooms to clean-lined, direct/indirect surface-mounted ceiling luminaires in corridors and offices, as well as self-supporting bundled installations in prominent locations such as the reception and waiting areas.
In particular, the expansive bundled installations create a deliberate architectural contrast to the functional restraint of the other areas.

REFLECTIONS THAT CONNECT
The ingenuity of the project also lies in the mounting systems developed specifically for the rod-shaped PINO Grande linear luminaires. The fixings were designed with reflective surfaces by the Merianos architectural office and never interrupt the continuity of the light-emitting surface. This creates the impression of a completely uninterrupted line of light.
At the same time, the stress-free gripping mounts allow the luminaires to rotate, enabling the light intensity to be directed precisely towards specific areas. This was a decisive feature, as the project had to be completed within a very short timeframe and the specific lighting requirements were not clearly defined in all areas from the outset.
In addition, the design allows for the lowest possible number of fixing points, thereby protecting the existing capillary tube cooling ceiling.
The lighting concept can therefore be summed up in just a few words: reduction to the essentials — and vice versa.


RELIABLE INTERACTION
As the luminaire supplier, Josef Barthelme GmbH & Co. KG supported the project. The key factors behind the collaboration were, in particular, the exceptionally high colour rendering values and the quality of the products, complemented by consistently high energy efficiency values and dedicated, solution-oriented communication throughout the entire project phase — even under considerable time pressure.
The successful collaboration between the Merianos architectural office and luminaire manufacturer Josef Barthelme GmbH has resulted in a breathtaking lighting system, whose implementation has been confirmed in both its aesthetics and functionality by the consistently positive response from the clients.
