Healthcare facilities typically use 3500K-4000K neutral white in patient rooms and general areas, as it balances clinical accuracy with a calming atmosphere. Operating rooms and examination areas require 4000K-5000K with CRI ≥90 and R9 ≥50 for accurate tissue and skin tone assessment. Patient rooms increasingly use tunable white lighting (2700K-6500K) to support circadian rhythms, with bright cool light during the day and warm dim light at night to improve sleep and recovery. Behavioral health and psychiatric units often use warmer 3000K light to reduce agitation. Always comply with local healthcare lighting standards (e.g., U.S. FGI Guidelines, EN 12464-1) when specifying hospital lighting.
