Low CRI makes objects look dull. High CRI is critical for retail, hotels, galleries.
| Application | Minimum CRI | Boyin standard |
| Warehouses | 80 | 80+ |
| Offices / Schools | 85 | 90 |
| Retail / Hotels | 90 | 95 (optional) |
| Art / Museums | 97+ | 97 (custom) |
Real case:
A jewelry client switched from CRI 82 to our CRI 95 downlights.
Sales staff reported “diamonds look 30% more brilliant” – and sales increased in the lit section.
Tip: Demand R9 value (deep red) > 50 for skin and wood tones.
