Light Quality

Beautiful form and outstanding light quality are the hallmarks of a Tobias Grau luminaire.

Our lights provide top CRI (80 to 90), advanced glare reduction, and intuitive light control. Glare reduction centres on our patented OSA (open structure anti-glare) technology, integrated across our XT-A range and featuring gridded LEDs in an open system, providing both optimal efficiency and glare-free illumination.

Our range of integrated dimming functions includes warmDIM technology to automatically adapt color temperature according to brightness, enhancing lighting for different moods and hours of the day while optimizing light for the body’s natural wake/sleep cycle.
