Abstract

Summary

This report provides expert consensus recommendations for lighting design based on melanopic EDI, a standardized metric for quantifying circadian-effective light exposure. The findings support optimizing light environments to promote sleep, neuroendocrine balance, and alertness, with particular relevance for populations whose non-visual light responses may differ from typical cone-mediated vision.
Abstract

Key Findings

  • An international SI-compliant standard for melanopic equivalent daylight illuminance (melanopic EDI) is recommended as the primary metric for specifying circadian-effective lighting.
  • Expert consensus recommendations are provided for lighting levels based on analysis of human circadian, neuroendocrine, and alerting responses to ocular light.
  • Studying individuals without cone-mediated vision helps isolate the role of melanopsin-expressing ipRGCs in mediating non-visual light responses.

Sleep & Circadian Health: Examines how ocular light exposure modulates circadian rhythms and sleep in people without cone-mediated vision, isolating melanopsin-driven effects.
The Science of Light: Discusses the international lighting standard and melanopic equivalent daylight illuminance (melanopic EDI) as a quantifiable metric for circadian-effective light.
