Which company is stronger in detecting the color rendering of light sources? BAIJIAN - a professional third-party testing and inspection platform that provides relevant testing and inspection services such as color rendering testing of light sources, and provides authoritative CMA/CNAS testing reports. The testing cycle is short, the cost is low, and the service is attentive, making the testing more than BAIJIAN Due to the fact that the same color sample may produce different color sensations for the human eye under different light sources, the color displayed by objects in sunlight is the most accurate. Therefore, daylight can be used as a reference light source to compare artificial light sources such as incandescent lamps, fluorescent lamps, and sodium lamps (to be tested) with it. This shows that the strength of the same color ability is represented by the so-called high or low color rendering index of the artificial light source&Nbsp&Nbsp; The national standard "Evaluation Method for Color Rendering of Light Sources GB5702-85" in China stipulates the use of Planck's radiation (color temperature below 5000K) and combined sunlight (color temperature above 5000K) as reference light sources. In order to test the degree of closeness between the color displayed by the object under the test light source and the color displayed under the reference light source, the "general color rendering index" is used as the intermediate indicator&Nbsp&Nbsp; The level of color rendering index indicates the degree of "color change" and "distortion" of an object under the light source being tested. The maximum color rendering index is 100. For example, if you first draw in sunlight and then observe it under a high-pressure fluorescent lamp, you will find that certain colors have "changed", such as pink turning into purple and blue turning into blue-purple. Therefore, under high-pressure mercury lamps, objects lose their "real" color
