Productivity uplift: ~18% improvement in task performance (CBRE x Twente / VU Amsterdam office study)
Accuracy gain: ~12% increase in work accuracy under rhythm-aligned spectrum (same study)
After-hours protection: M/P ratio <0.35 after 18:00 - reduces melanopic load for personnel remaining on-site
SVM compliance: <0.40 across all CCT states - eliminates flicker-related visual fatigue complaints
WELL alignment: Daytime m-EDI >135 lx (equivalent to WELL v2 Feature L03 threshold of 150 EML)
This program includes a pre-configured DALI-2 / Casambi scene file ready for immediate deployment to your lighting controller.
