Summary
Patients prefer lighting conditions below 5,000K CCT, finding higher CCTs significantly less comfortable and less natural, while multi-zone distributed lighting is favored over traditional single overbed configurations. Colored footwall lighting was negatively received, but blended warm and cool CCT combinations were acceptable, offering practical guidance for hospital room lighting design.
Key Findings
- CCTs of 5,000K and higher were rated significantly less comfortable and less natural than lower CCT conditions
- Multi-zone distributed lighting arrangements were viewed more favorably than traditional overbed lighting configurations
- Colored lighting on the footwall was reacted to negatively by simulated patients
- A mixture of warmer and cooler CCT luminaires was found acceptable by participants
Categories
Patient Recovery: Evaluates patient comfort and preference across different lighting configurations in simulated hospital rooms.
The Science of Light: Examines how correlated color temperature (CCT) and luminaire distribution affect perceived comfort and naturalness in healthcare settings.
