Lighting Days

When & Where

The purpose of Lighting Days is to present a broader perspective of sustainability lighting which includes aspects from regulations, components and recycling to perceived light quality and wellbeing.

The event follows directly on from Light Symposium 2023, which is being hosted by the Architectural Lighting Design Division of KTH Royal institute of Technology in Stockholm and which together with Lighting Days will provide a full week of light-related gatherings, workshops and presentations.

Our expectation is to attract participants from a wide range of professions and stakeholders engaged in light including; lighting designers, light researchers, architects, representatives from industry and real estate, installers, local authorities and property managers.

Higher demands on not only energy efficiency but also resource efficiency, or even resource sufficiency, calls for continuous development at all levels, from the light source at the luminaire level to the final lighting system level.

This means everyone from manufacturers, lighting consultants, lighting designers, to procurers and even normal consumers must continue to learn to master the new possibilities to fulfill the potential of good lighting for everyone while using a minimum of resources.

Welcome to two and a half invigorating days of presentations, discussions, workshops, networking, light- and wine tasting and a light and sound art evening event.

Part 1 – Welcome Lunch and Presentations

Wednesday 6th December 12:00-16:30


Part 2 – Circadian Waves: Resonances

Wednesday 6th December 18:00-20:00


Circadian Waves: Resonances is a light and sound installation at Scenkonstmuseet (Swedish Museum of Performing Arts) which is inspired by Nobel Prize Winners and part of the Nobel Week Lights festival which is also taking place across Stockholm this week.

The installation is a collaboration between Royal Institute of Technology (KTH), University of Arts, Crafts and Design (Konstfack), Stockholm University of the Arts (SKH) and Royal College of Music (KMH).

“Through a light and sound installation, visitors can experience the shifts between light and darkness, sound and silence in the middle of an urban environment, resonating with our internal, lost rhythms.

The Nobel Prize winners who inspired us for the installation were Jeffrey C. Hall, Michael Rosbash and Michael W. Young, for their discoveries of molecular mechanisms controlling the circadian rhythm. They received their prize in 2017.”
