The object shows its true color under the sunlight and incandescent lamp, but when the object is illuminated by the discontinuous spectrum gas discharge lamp, the color will have varying degrees of distortion. We call the degree of the light source to the true color of the object as the color rendering of the light source.
In order to quantitatively evaluate the color rendering properties of light sources, the concept of color rendering index is introduced. Based on the standard light source, the color rendering index is set to 100, and the color rendering index of other light sources are all lower than 100. The color rendering index is expressed by Ra. The greater the value of Ra, the better the color rendering of the light source.
The default color rendering index of our products is above 80. At present, Europe also requires LED lights Ra>80, but customers in different regions still have their own standards.
