2. High-CRI LED lighting - Wikipedia

   en.wikipedia.org/wiki/High-CRI_LED_lighting

   The higher the CRI value, the smaller the differences between indices will be. A CRI value of 100 indicates the best performance of a light source, while a low CRI value may result in some colors looking unnatural. The most commonly used value of CRI is called Ra, which is the average value of the first eight indices (R1-R8).

3. Color rendering index - Wikipedia

   So, generally, it is regarded as a supplement of color rendering index when evaluating a high-CRI light source. R9 value, TCS 09, or in other words, the red color is the key color for many lighting applications, such as film and video lighting, textile printing, image printing, skin tone, medical lighting, and so on.

4. LED lamp - Wikipedia

   The light is not the same as a true black body, giving a different appearance to colors than an incandescent bulb. Color rendering quality is specified by the color rendering index (CRI), and as of 2019 is about 80 for many LED bulbs, and over 95 for more expensive high-CRI LED lighting (100 is the ideal value).

5. Color rendering - Wikipedia

   en.wikipedia.org/wiki/Color_rendering

   The color rendering index (CRI) of 1974 is the product of a CIE committee's study on the topic of color rendering. It uses the American colorimetric approach with a panel of human subjects instead of requiring spectrophotometry. Eight samples of varying hue would be alternately lit with two illuminants, and the color appearance compared.

6. L Prize - Wikipedia

   The lamp was comparable to a 60W incandescent in color quality (CRI = 93, CCT = 2727 K), light distribution, and light output (940 lumens) but consumed less than 10W (a savings of 83%), and at 25,000 hours of testing, the actual lumen maintenance was 100%, with chromaticity change at less than .002.
