Content | In architecture, Light Reflectance Value (LRV), is a measure of the percentage^[1] of visible and usable light that is reflected from a surface when illuminated by a light source. The measurement is most commonly used by design professionals like architectural color consultants, architects, environmental graphic designers and interior designers. LRVs are frequently reported on paint chips or paint samples. The values are used by lighting designers to calculate the number and type of light fixtures needed to provide a certain amount of light for interior spaces.
