Summary
This paper reviews the state of circadian lighting science in the context of architectural design, highlighting the gap between controlled laboratory findings and real-world daytime lighting conditions in built environments. It underscores the challenge of translating extreme lab-based light exposure studies into practical guidance for lighting designers and architects.
Key Findings
- Laboratory studies on circadian photoreception typically use nighttime conditions and extreme, controlled light exposures, making direct applicability to daytime architectural environments difficult to assess.
- The practical relevance of ipRGC-mediated non-visual responses (alertness, sleep, health) for architectural lighting design remains ambiguous due to the disconnect between experimental and real-world conditions.
Categories

Sleep & Circadian Health: Addresses how ocular light exposure affects circadian phase, melatonin levels, and neurobehavioral processes relevant to real-life daytime conditions.
