What is CRI?

CRI is a measurement that assesses how a light source renders colours in comparison to natural sunlight. The index operates on a scale from 0 to 100%, where a higher score indicates more accurate colour rendering. In other words, lighting with a high CRI score will display colours more accurately, which is crucial for an accurate presentation of your products.

Why is CRI important in Shop lighting?

The right lighting can significantly improve the customer's shopping experience. A high CRI level helps present products in their true colours, making them more attractive and inviting. This is especially important in retail environments where aesthetic appeal is key to driving sales. By investing in high-CRI lighting, retailers can create a visually satisfying experience that encourages customers to buy.

Using CRI in Practice

High CRI lighting is especially beneficial in stores that sell clothing, electronics, or food as it helps bring out the true colours of the products. A CRI score of 80 to 90 is considered good, while a score of 90 or higher is considered excellent for colour rendering, making it ideal for larger retail environments.
