What is the display index of the LED lamp?
For LED lamps, the average color index of the three primary colors is high, and the color index of the blue and yellow phosphors is not as high as the three primary colors of the LED.
A light source with a Ra value of 100 indicates that the color displayed in the light of the object is consistent with that under the standard light source.
The degree to which an object's color is rendered is called color rendering.Usually called the color rendering index (Ra)
