Summary
This paper establishes foundational principles for biodynamic ('life-centric') lighting by grounding design recommendations in the photobiology of melanopsin-containing ipRGCs, with peak circadian efficacy in the 450-480 nm blue wavelength range. Practitioners can use these principles to inform dynamic lighting systems that support human circadian health across various environments.
Key Findings
- Melanopsin-driven circadian responses are most efficiently stimulated in the 420-500 nm wavelength range, with peak efficiency between 450-480 nm.
- ipRGCs in mammals are identified as the primary photoreceptors mediating non-visual, circadian light responses relevant to biodynamic lighting design.
