CRI (Color Rendering Index) vs CCT (Correlated Color Temperature): what each measures, recommended values by application…
| 对比维度 | 选项A | 选项B | 优胜 |
|---|---|---|---|
| What It Measures | Color accuracy (Ra 0-100) | Light color appearance (Kelvin) | Different purposes |
| Office Recommendation | CRI ≥80 | CCT 3500-5000K | Both matter |
| Retail Recommendation | CRI ≥90 | CCT 2700-3500K | Both matter |
| Museum/Gallery | CRI ≥95 (R9 ≥90) | CCT 2700-3500K | CRI more critical |
| Warehouse/Industrial | CRI ≥70 (sufficient) | CCT 4000-6500K | CCT more critical |
| Healthcare | CRI ≥90 (R9 ≥50) | CCT 3500-4500K | Both equally critical |
| Hospitality/Hotel | CRI ≥90 | CCT 2700-3000K | CRI more critical |
| Cost Impact | CRI 95 costs 30-50% more | CCT has minimal cost impact | CCT (no premium) |
CRI和CCT服务于不同目的。CRI(Ra)衡量色彩准确性——零售、博物馆、医疗关键。CCT(Kelvin)决定氛围和视觉舒适——暖色(2700-3000K)放松，冷色(4000-6500K)提神。采购中两者都应明确指定：切勿仅凭一个参数决策。
