Interventions
Application of an optimized ambient lighting condition through placement of a dimmable LED floor lamp in participants' private workspaces to create a standardized workplace lighting environment during working hours. The floor lamp emits white light with a specified spectral distribution and intensity. Participants may adjust brightness for comfort. The lighting system is used solely to modify the ambient workplace lighting environment during the 4-week intervention period.
