High-CRI LED lighting is a light-emitting diode (LED) lighting source that offers a high color rendering index (CRI). CRI is a quantitative measure of a light's ability to reproduce the colors of objects faithfully in comparison with an ideal or natural light source.
Many lights manufacturers or retailers do not point out the score of R9, while it is a vital value to evaluate the color rendition performance for film and video lighting, as well as any applications that need high CRI value. So, generally, it is regarded as a supplement of color rendering index when evaluating a high-CRI light source.
Color quality scale (CQS) is a color rendering score – a quantitative measure of the ability of a light source to reproduce colors of illuminated objects. Developed by researchers at NIST [1] the metric aims to overcome some of the issues inherent in the widely used color rendering index (CIE Ra, 1974).
Television lighting consistency index (TLCI), EBU 2012. Address the spectral response of cameras and screens, which can have significantly different results with high-CRI LED lighting. [3] Spectral similarity index (SSI), AMPAS 2016 (revised 2020). Ditches the concept of color samples in CRI and TLCI to directly address the shape of the spectrum.
L08 Electric Light Quality, for quality of light fixtures, total 3 points, all light fixture, except decorative lights and emergency lights, that color rendering is equal or over color rendering index (CRI) of 90 or CRI of 80 with R9 equal or over than 50 or TM-30 of color rendering fidelity (Rf) equal or more than 78 and color rendering gamut ...
The "Film and video high-CRI LED lighting incompatibility" section describes the applicability of CRI scores to film and video results. Still digital photography is not specifically mentioned. Could such material be added? — Preceding unsigned comment added by Dmk5717 (talk • contribs) 17:52, 3 June 2019 (UTC)
