Summary
This practice review identifies conflicts between existing visual lighting standards and emerging recommendations for non-visual (circadian) lighting effects, noting that standard-compliant lighting often delivers insufficient melanopically effective light. The paper concludes with integrated lighting recommendations designed to satisfy both visual comfort and non-visual health requirements.
Key Findings
- Compliance with conventional visual lighting standards often results in insufficient non-visually effective (melanopic) light reaching the eye.
- Existing regulations do not yet include specific requirements for temporal or spectral variation of light to support circadian health.
- The review concludes that there is a conflict between current visual lighting standards and new non-visual lighting recommendations, requiring updated integrated guidance.
Categories
The Science of Light: Reviews lighting standards and regulations, contrasting visual lighting requirements with new recommendations for non-visual (circadian) effects of light.
Workplace Performance: Addresses how compliance with visual lighting standards may limit non-visually effective light, with implications for alertness and cognitive performance in daytime settings.
