Hospital Lighting Is About Clinical Accuracy
In a hospital, getting the lighting right is not just about brightness. The right light helps doctors and nurses identify subtle changes in a patient's condition, make confident visual assessments, and act quickly.
For healthcare projects in Australia and New Zealand, tenders often specify AS/NZS 1680.2.5 related requirements such as COI < 3.3, CRI > 95, and R9 > 90 for LED panel lights.
What COI, CRI, and R9 Mean on the Hospital Floor
Each value addresses a different clinical lighting risk: cyanosis visibility, general color accuracy, and critical red tone rendering.
Cyanosis Observation
COI measures how well a light source allows medical staff to detect cyanosis, the bluish skin tint that can indicate low oxygen. Keeping COI below 3.3 helps render skin tones more naturally.
Reliable Color Rendering
CRI shows how accurately colors appear under artificial light. In wards and exam rooms, high CRI helps clinicians assess rashes, jaundice progression, and other visible symptoms more clearly.
Critical Red Tone Accuracy
R9 measures saturated red rendering. Blood, bruising, inflammation, wounds, and tissue condition all depend on accurate red perception in medical observation.

Conclusion: Hospital Lighting Must Support Clinical Judgement
ShineLong believes hospital LED lighting should be evaluated by clinical visibility, not brightness alone.
From ShineLong's perspective, COI, CRI, R9, SDCM, UGR, and efficacy work together: COI supports cyanosis observation, CRI supports general color accuracy, R9 supports red tone recognition, and UGR helps protect long-term visual comfort.
ShineLong recommends confirming these values early in Australian and New Zealand healthcare lighting projects so panel light selection supports both compliance review and daily clinical use.
