3. Color temperature - Wikipedia

   en.wikipedia.org/wiki/Color_temperature

   For lighting building interiors, it is often important to take into account the color temperature of illumination. A warmer (i.e., a lower color temperature) light is often used in public areas to promote relaxation, while a cooler (higher color temperature) light is used to enhance concentration, for example in schools and offices. [15]

   CIE Publication 15:2018 introduces nine new illuminants representing several white LEDs with CCTs ranging from 2700~6600 K. [28] LED-B1 through B5 define standard LED illuminants with phosphor-converted blue light. LED-BH1 defines a blend of phosphor-converted blue and a red LED. LED-RGB1 defines the white light produced by a tricolor LED mix ...

6. High-CRI LED lighting - Wikipedia

   en.wikipedia.org/wiki/High-CRI_LED_lighting

   CRI is calculated from the differences in the chromaticities of eight CIE standard color samples (CIE 1995) when illuminated by a light source and by a reference illuminant of the same correlated color temperature (CCT), commonly measured in kelvins, indicating the light color produced by a radiating black body at a certain temperature; the smaller the average difference in chromaticities, the ...

7. Color rendering index - Wikipedia

   en.wikipedia.org/wiki/Color_rendering_index

   CIE (2007) "reviews the applicability of the CIE color rendering index to white LED light sources based on the results of visual experiments". Chaired by Davis, CIE TC 1-69(C) is currently investigating "new methods for assessing the color rendition properties of white-light sources used for illumination, including solid-state light sources ...
