Light control strategies. Nighttime (00:00 h–06:25 h) and daytime (07:00–20:00 h) melanopic daylight-equivalent illuminances were reduced by 78% and increased by 46% under DD-N lighting compared to standard bedroom lighting, respectively. The lighting control system actually changed the light intensity and light color during dawn and dusk linearly over time (dawn: 6:25–07:00 h; dusk: 20:00–00:00 h).
