Understanding 70 CRI vs 82 CRI vs 97 CRI Lighting

CRI (Colour Rendering Index) measures how accurately a light source reveals true colours compared to natural daylight. Higher CRI lighting improves product appearance, inspection accuracy, visual comfort, and perceived quality.

Higher CRI lighting delivers significantly better colour accuracy and visual quality.

Why 97 CRI Creates Higher Value

Not every area needs 97 CRI lighting. However, in zones where colour judgment, product appearance, inspection quality, or customer perception matter, high CRI lighting can significantly improve outcomes.

Higher CRI lighting should be selectively used in high-value visual zones.

High-value applications for 97 CRI lighting:

• Food processing and restaurants – food looks fresher and more appealing
• Textile and printing industries – accurate colour matching
• Inspection and quality control areas – improved defect visibility
• Showrooms and premium retail – enhanced product presentation
• Healthcare and laboratories – natural visual perception

Tucana Recommendation

Use 82+ CRI lighting for general industrial applications and selectively deploy 97 CRI lighting in critical visual zones to improve quality perception, inspection accuracy, and customer experience.
