The CIE is excited to announce the release of the third edition of its Position Statement on Integrative Lighting — "Recommending Proper Light at the Proper Time." This updated document, which builds on the 2019 edition, incorporates the latest research and recommendations from the Second International Workshop on Circadian and Neurophysiological Photoreception held in Manchester, UK.
As our understanding of how light affects human health, behavior, and well-being evolves, so does the CIE’s commitment to integrating this knowledge into practical lighting solutions. The third edition of the Position Statement provides a comprehensive overview of the workshop's findings and highlights crucial areas for further exploration.
Key Highlights Include:
- Balanced Lighting Quality: Emphasizes the need to harmonize human well-being in all its aspects with energy, environmental, and architectural considerations.
- CIE S 026:2018 Compliance: Characterizing light for integrative effects should adhere to the CIE S 026:2018 standard, the CIE System for Metrology of Optical Radiation for ipRGC-Influenced Responses to Light.
- Guidance on Light Exposure: International experts meeting in Manchester, UK, recommended a healthy daily light exposure pattern for young adults: high light exposure during the day, a much lower level for the three hours before bed, and near-darkness during sleep.
- Design Considerations: Urges careful design to avoid glare and manage lighting energy use while achieving high-quality integrative lighting.
- Public Guidance: Today, we know enough about the effects of lighting on health to provide general guidance to the public, which the CIE, in collaboration with other international partners, will offer in the coming months.
This updated Position Statement reflects the CIE’s ongoing dedication to advancing lighting science and its application in improving daily life. For more details and to download the full document, visit the CIE webpage for Position Statements.
