Summary
Work-from-home lighting environments frequently fall short of both commercial illuminance and circadian lighting standards, with artificial lighting achieving only 7.5% of required EML levels—posing risks to circadian health and visual comfort. Despite this, most participants were unaware of inadequate lighting, though 80% expressed preference for human-centric lighting (HCL) task solutions, suggesting strong market potential for circadian-supportive home office products.
Key Findings
- Only 7.5% of required EML was achieved under artificial lighting alone in WFH environments.
- 34.3% of recorded EML readings fell below regulatory requirements even under daylight conditions.
- Mean lux level recorded was 452.4 lux with 0.729 uniformity, below commercial standards for common WFH tasks.
- 80% of WFH installations met general safety lighting requirements but not commercial task-lighting standards.
- 46.2% of participants reported noticeable headaches or eye strain when working from home.
- 80% of participants indicated HCL task lighting would be preferable to their current setup.
- 63.2% of participants would not accept more than a 10% efficiency reduction compared to non-HCL systems.
- Participant lighting priorities ranked: wellbeing first, followed by efficiency, home impact, and cost.
