For supermarket fresh food departments including meat, seafood, fruit, vegetables and bakery, a CRI of 90 or higher is strongly recommended. High CRI lighting renders food colors naturally and vividly, making products look fresher and more appealing to shoppers, which directly boosts sales and reduces waste from unsold goods. Standard CRI 80 is acceptable for general aisles, storage areas and checkout zones where color accuracy is less critical. For premium stores, consider CRI 95+ with specialized spectrum tuning for specific food categories. Always verify the actual CRI value in the product datasheet rather than relying on marketing claims.
