EFFICACY METRICS

Low-melanopic close: Pre-sleep mode holds m-EDI <10 lx through the late-evening phase, aligned with CIE S 026 guidance for melanopic-suppression avoidance

Guest comfort: Seamless 5-phase transition eliminates abrupt light changes - light follows the guest's operational rhythm

Night safety: Motion-triggered 2200K at 10 lx provides navigation with minimal melanopic exposure

WELL alignment: Supports WELL v2 Feature L03 (circadian lighting design) for certified hospitality projects

This program includes a pre-configured DALI-2 / Casambi scene file ready for immediate deployment to your lighting controller.
