CRI stands for Color Rendering Index, which reflects the ability of lights to restore real object colors. For supermarket fresh areas including fruit, vegetable, meat and seafood zones, CRI ≥90 is strongly recommended to restore natural food colors and attract customers. For general aisles, shelf areas and warehouse zones, CRI 80 is sufficient to balance lighting quality and project cost. Professional high-CRI lighting can significantly improve product display effects and overall store grade.
