Light Reflectivity – Why it’s Important

All light reflectivity values listed are based on a percentage system, the higher the percentage (e.g. 20-24, 35-39), the higher the light reflectance of the floor. It is measured by ASTM E1349, Standard Test Method for Reflectance Factor and Color by Spectrophotometry Using Bidirectional (45°:0° or 0°:45°) Geometry.

Research indicates reflectance can help drive daylight further into space and reduce reliance on artificial lighting, resulting in reduced electricity usage and costs. Glare from flooring is a characteristic of glossy finishes, not reflectance. Flooring in lighter colors with a matte finish have high reflectance values, but do not add to glare. Flooring with light reflectivity values greater than 25% can contribute to the LEED® Interior Lighting Credit.
