Gentle lighting – poetry for the eyes.

The ubiquity of mobile screens in smartphones, tablets and laptops in today’s world means that glare-free lighting is a requirement that is not just confined to the office. In future, there will be a demand for a pleasant lighting atmosphere restricting direct glare for every environment.
At RZB, our guiding principle is to focus on developing the kind of lighting systems that provide glare-free, gentle LED light in outstanding quality through transparent perspex surfaces for universal use. The intention is also to achieve a magical lighting effect with the characteristics of “minimalist form” and “transparent light control”, which make the luminaires suitable for open use in any architectural environment. These stimulating lighting systems are also ideal for supporting the biodynamic daylight rhythm (HCL). These tunable white versions are particularly good for users’ emotional well-being.
RZB has created the TWINDOT range of LED suspended luminaires as the first product family to achieve a magical lighting effect. These lighting systems are based on the two designs for a new generation of light-decoupled microprismatic and authentic system design by the reputed designer Hartmut S. Engel, with whom RZB has worked successfully for a long time now.
The “TWINDOT light technology” ensures the success of the transformation: the innovative microprismatic transforms the total reflection of the light waves in the transparent perspex into a magical light. The room is bathed in a glowing and gentle light with soft shadows and glare-free light to see and work by. Gentle light poetry becomes a sensual experience.

Transformation from transparency into light

Transformation from transparency into light

The mystical transformation of a transparent surface into bright fullness of light in the room is sure to enchant every observer.

LED light technology for perfect vision

LED light technology for perfect vision

A transparent light guide measuring just 6 mm thin and made of UV-resistant acrylic glass (PMMA) is equipped with the TWINDOT microprism structure in a hot-embossing process. This structure consists of microfine twin prisms, which have been applied to the top surface of an acrylic sheet in a defined angle matrix. This serves to decouple the light and bathe the room in gentle, glare- free lighting with soft shadows - perfect for evenly lit ceilings, walls and work surfaces, and ideal for a wide variety of screen-based tasks.



Exceptional LED individual luminaire formats: Extra flat and exclusive.



Expansion of the product family with concentric formats. Lively diversity with the same design for the planning of emotional light experiences.
