== 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 only specify CRI. You want something with CRI over 95. An important color not taken into account by CRI is 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.
