In the world of lighting, the Color Rendering Index (CRI) plays a crucial role. This index, ranging from 0 to 100, measures the ability of a light source to accurately reproduce the colors of objects compared to a natural or ideal light source.

What is CRI?

CRI is a metric that evaluates how a light source affects the appearance of the colors of the objects it illuminates. A higher CRI indicates that the light is capable of showing colors more faithfully to how they would appear under sunlight. A CRI of 100 represents perfect color rendering, similar to natural light.

What is CRI used for?

Color accuracy is vital in many fields. A high CRI ensures that colors are perceived correctly, without distortions. This is especially important in:

• • Art and photography studios: Where artists and photographers rely on accurate color representation for their work.

  • Health centers and hospitals: Where correct color perception can be critical for diagnoses and treatments.

  • Clothing and fashion stores: Where accurate colors can influence purchasing decisions.

  • Interior design: To ensure that the colors of walls, furniture, and decorations appear as intended.

When to apply each CRI?

• • CRI 80-90: This range is suitable for most daily environments such as offices, schools, and homes. It provides good color rendering, adequate for most everyday activities.

  • CRI 90-100: Ideal for applications where color accuracy is critical. This includes art galleries, photography studios, and certain medical environments where color accuracy can be essential.
    
    

Benefits of Good Lighting

Adequate lighting not only enhances the aesthetics of a space but also has multiple functional and psychological benefits. Good color rendering can:

• • Improve mood and well-being: Light that shows colors naturally can make spaces feel more welcoming and pleasant.

  • Increase productivity: In work environments, better color perception can reduce eye strain and increase efficiency.

  • Foster accuracy and quality: In industries such as manufacturing and medicine, correct color perception is crucial for the quality and accuracy of work.

📍 Success Story in Gran Canaria

Recently, we had the privilege of participating in a project at a Child Development and Therapy Center in Gran Canaria. In this project, choosing the correct CRI was essential to creating an optimal environment for the children. We used luminaires such as the Tube Pendant and the Line, ensuring excellent color rendering that significantly contributed to the well-being and development of the children.

This project is a clear example of how a correct lighting selection, based on CRI, can make a significant difference in sensitive and specialized environments. Children greatly benefit from lighting that allows them to perceive colors naturally and accurately, which is essential for their cognitive and emotional development.
