Color rendering
== Color rendering ==
The the most common standard is [https://en.wikipedia.org/wiki/Color_rendering_index CRI]. Unfortunately, CRI is pretty useless, but consumer manufacturers frequently only specify CRI. You want something with CRI over 95. An important color not taken into account by CRI is [https://www.waveformlighting.com/tech/what-is-cri-r9-and-why-is-it-important/ R9]. You want something with R9 over 90.
A much better standard is [https://tech.ebu.ch/tlci-2012 TCLI]. You want something with TCLI over 90.
