CRI 80 vs CRI 90 in Commercial Spaces Comparison
Where the extra colour fidelity pays for itself, and where it is wasted.
CRI 90 costs more and delivers less light per watt. That trade only makes sense in rooms where people judge colour — food, fabric, skin, finish.
| Comparison | Option A | Option B | Winner |
|---|---|---|---|
| Warehouse aisles | Sufficient for labels and safety colours | Not needed | CRI 80 |
| Retail and grocery | Flat produce, muted packaging | Standard for fresh food and fabric | CRI 90 |
| Offices | Acceptable | Noticeable on wood, textiles and skin | CRI 90 |
| Healthcare | Corridors and plant rooms | Examination and patient areas | CRI 90 |
| Efficacy | Typically 5-12% higher at CRI 80 | Lower, but improving | CRI 80 |
| Cost delta | Baseline | About 8-20% per luminaire | CRI 80 |
Conclusion
Keep CRI 80 in warehouses, plant rooms and back-of-house, and specify CRI 90 with R9 above 50 wherever merchandise or skin tone is being assessed. Ask for the LM-79 report before accepting the claim.
