Scope
RP-29 is the applications standard for lighting design in hospitals, including inpatient rooms. It defines target illuminance for exam, ambient, and night settings, plus glare, color rendering, and circadian considerations.
Where it applies in the room
- Exam light illuminance at the bed
- Ambient and night-mode lighting
- Color rendering (CRI) and correlated color temperature
Key requirements at a glance
| Exam lighting | Higher task illuminance at the patient for examination, separately controlled from ambient light. |
|---|---|
| Ambient lighting | General patient-room lighting with controls for patient and staff. |
| Night lighting | Low-level lighting for safe movement at night with minimal sleep disruption. |
Summarized for reference. Consult the source document for the definitive text.
Caveats
- RP-29 is a recommended practice, not a code; target values are in the paid official text.
