XT-A PLUS

Floor or table-affixed lighting

Outstanding Light Quality

Uncompromising brilliance

With its advanced LED technology and patented OSA light panel, XT-A PLUS beams beautiful, adaptable and de-glared light at maximum energy efficiency.

Outstanding Light Quality

Cutting-edge LEDs provide powerful illumination of 11467 / 14140 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 85% 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 Colour Rendering Index of > 80 delivers a top colour spectrum, ensuring workspace lighting is vibrant, focused, and precise.

Smart Sensor System

Light in sync

XT-A PLUS is equipped with a motion sensor and constant light regulator. Our motion sensor allows customers to program specific customer and usage requirements, such as restricted motion detection or temporary deactivation.

Smart Sensor System

For optimal energy efficiency, the constant light regulator adjusts the light according to ambient brightness while the motion sensor detects when the workstation is not in use.

Flexibility

Illumination for every space

Sleek and linear, XT-A PLUS is designed to integrate smoothly and harmoniously into any workplace, with floor and table-mounted models for flexible planning.

Flexibility

Choose XT-A PLUS as a free-standing or table-affixed model, according to workspace set-up and requirements.

Connectivity

Networked illumination

XT-A PLUS is compatible with Tobias Grau CONNECT and Indirect Light Control technologies, enabling group programming of multiple lights and advanced coordination of ambient illumination.

Connectivity

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.

ILC (Indirect Light Control) is an additional lighting tool to our CONNECT swarm function. It allows for coordination of indirect light between groups of luminaires, while direct lighting can be adjusted individually. An advanced ambient light management for exceptionally harmonious room illumination.

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.
