Choosing the right color temperature for retail depends on your product category and brand positioning. Fashion and apparel stores often use 3000K-3500K warm white to flatter skin tones and create an inviting atmosphere. Electronics, jewelry and high-end boutiques may use 4000K neutral white for accurate color representation. Fresh food retailers need 4000K-5000K with high CRI to make products look vibrant. Luxury brands sometimes use 2700K warm light for an exclusive, intimate feel. Consider using different CCTs in different zones: warm light in display windows and fitting rooms, neutral white in main shopping areas. Always test lighting with actual merchandise before full installation.
