Bartenbach’s "Personal Table Light" (PTL) receives Best Product Award 2020

Bartenbach was the leader of the EC-funded research project Repro-light, which aimed to successfully initiate transformation in the European LED lighting industry, by creating the ‘Luminaire of the Future’. Part of this remit was to develop a new customizable lighting system.

The Personal Table Light (PTL) developed by Bartenbach as part of Repro-light has now been awarded with a Best Product Award 2020 at the LpS Digital 2020 ( The PTL is a user-centered, intelligent lighting system that is revolutionizing workplaces and focuses on the health and well-being of the user.

Bartenbach started with an extensive European wide user survey to fully understand the requirement for better lighting, which established the requirement for an easy to use, customizable lighting system.

The PTL achieves exceptional lighting for vision and health at the workplace and is fully personalizable. Visual performance is perfectly supported as both vertical and horizontal workspace surfaces are lit separately, and illuminance levels are controlled along with light colour temperatures, and light distributions. Furthermore, the PTL effectively delivers up to 1500 lux at eye level, meaning missing daylight is supplemented and is able to exert non-visual effects on mood, alertness, performance, and nighttime sleep. The PTL also allows full customization of scenes by the user via a desktop application.

Equipped with single-point LED controls and a highly innovative sensor technology that recognizes the actual activity of the user, lighting scenes adjust discreetly and automatically according to changing visual activities.

Additionally, environmental quality is assessed continuously by ambient temperature, humidity, air pressure, volatile organic compounds, and sound level sensors. Therefore, the luminaire uses highly standardized IT-protocols, which enable an easy integration of nearly all sensors available on the market.

Finally, using cloud connectivity, user activities can optionally be recorded which allows an on-going optimization of the lighting system tailored to individual needs.

The application possibilities of the PTL are numerous and range from student areas, offices, to medical and manufacturing workspaces.

The future of human centric lighting has arrived. With patent pending, the PTL has the potential to transform workspace lighting. To verify the expected effects on visual performance, well-being and health impact research is currently being conducted in laboratory and field studies.
