The CIE 84 colorimetric measurement using an integrating sphere is a technique that is used in the process of determining the color characteristics of a light source. In line with the CIE 84 standard for the color rendering index (CRI), this measuring technique is used to determine the color rendering qualities of lighting systems such as LED lights and other types of lighting. The color rendering index, or CRI, is a numerical measurement that ranges from 0 to 100 and indicates how well a light source can reproduce the colors of objects in comparison to a standard light source. During a CIE 84 colorimetric measurement using an integrating sphere, light from the LED light source is directed into the sphere, and the light from the LED light source is then diffused uniformly around the inside surface of the sphere. A spectroradiometer is used to make precise measurements of the homogeneous light field that is produced by the inside surface of the sphere, which functions as a diffuse re
