P3. Nightlights
Child care and bathroom breaks are some of the reasons why individuals may need to navigate an interior space at night. Traditional lighting can disrupt sleep more than necessary during these late night activities.
Given the lower impact of red wavelengths of light (relative to other color wavelengths) on sleep, this feature is designed to help way-finding with minimal light and minimal circadian disruption.
