Outstanding Light Quality
Cutting-edge LEDs provide powerful illumination of 14500 / 16000 Lumen at AA+ energy efficiency.
The XT-A PLUS provide an outstanding level of indirect light, ensuring holistic and balanced brightness throughout the workplace. In addition to the pristine illumination of the workstation, the luminaire distributes 89% of its light into the surrounding room.
Our OSA (Open Structure Antiglare) technology features gridded LEDs in an open system, providing advanced efficiency and superior glare-free lighting. This ergonomic innovation improves workplace wellbeing, performance, and visual comfort, especially for screen-based tasks.
A Color Rendering Index of > 80 delivers a top color spectrum, ensuring workspace lighting is vibrant, focused, and precise.
Swarm function allows lamps to communicate amongst themselves, so that in an open office environment, not only is the luminaire bright in the area of the recognised presence, but also in the area surrounding the luminaire. This increases the visual comfort, reduces fatigue and increases the sense of security.
XT-A is our essential lighting solution for the contemporary workplace. The series pairs fresh, minimalist design with our most sophisticated technologies to champion workplace style, sustainability, and wellbeing. Designed for maximum flexibility, the series includes models for multiple workplace configurations, including for height-adjustable desks. Patented anti-glare technology helps create optimal conditions for reading and working, especially for screen-based tasks.
