Summary
This paper argues that current lighting metrics (lumens and CRI) fail to capture the full spectrum of benefits lighting can provide, leading to wasteful and suboptimal lighting design. Adopting new benefit metrics would allow practitioners to design more efficient, human-centric lighting systems that address visual, biological, and wellbeing outcomes.
Key Findings
- Lumens and CRI represent only a small fraction of the actual benefits lighting can provide to occupants.
- Lack of comprehensive benefit metrics leads to unnecessary waste of capital, operational expenses, and natural resources in lighting installations.
- The paper advocates for new formal metrics that would make lighting design more valuable and less wasteful, though no specific quantitative experimental results are reported.
