XT-A SINGLE

Streamlined light for a single workstation

Outstanding Light Quality

Uncompromising brilliance

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

Outstanding Light Quality

Cutting-edge LEDs provide powerful 6000 Lumen illumination at AA+ energy efficiency.

XT-A SINGLE provides an outstanding level of indirect light, ensuring holistic and balanced brightness throughout the workplace. In addition to pristine illumination of the workstation, the lamp distributes 74% 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

The XT-A SINGLE 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

For an agile workspace

Streamlined for the contemporary workplace, XT-A single is designed for nimble, flexible, use – including full compatibility with height-adjustable desks.

Flexibility

XT-A SINGLE is fully compatible with height-adjustable desks, moving with the work surface as it is lowered or raised. Whether seated or standing, light is evenly and consistently distributed over the working area.

XT-A SINGLE is securely integrated into the desk or flexibly attached via a clamp. In either configuration, lamp and workstation can be moved as a single, streamlined unit.

Connectivity

Networked illumination

XT-A SINGLE 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.
