Oppose - It should not be merged, however there ought to be something in the text that explains the use of the CRI with respect to current lighting technologies. (e.g. fluorescent tubes, LED replacements for incandescents, etc) Any chance someone can offer clarification about what is meant by "perceived"? (Quoting from the article page, "The perceived colors under the reference and test illumination ...". The "perceived colors" can be determined by a human, which isn't subject to calibration, or it can be determined by a device that would be calibratable (if this is a word) to a spectrum based on known wavelengths. <!-- Template:Unsigned --><small class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[User:JohnP|JohnP]] ([[User talk:JohnP#top|talk]] • [[Special:Contributions/JohnP|contribs]]) 08:36, 19 April 2006 (UTC)</small>

Oppose -- CRI is a very specific and measurable quality of light. Perhaps a better solution would be to create a more general "Color Rendering qualities of Light" topic wherein various measurables both quanititive and qualitative could be discussed <!-- Template:Unsigned IP --><small class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/161.88.255.139|161.88.255.139]] ([[User talk:161.88.255.139#top|talk]]) 17:43, 2 May 2006 (UTC)</small>

The "perceived colors" can be determined by a human, which isn't subject to calibration, or it can be determined by a device that would be calibratable (if this is a word) to a spectrum based on known wavelengths.

Support (with caveats) - I agree with the above unsigned commenter that CRI is usually use to refer to CIE Ra. I suggest that this page (Colour Rendering Index) be broadened to note this fact but refer to the concept of colour rendering indices more broadly, with CIE Ra obviously forming a large part of that. This would open the door for the inclusion of Gamut Area Indices, the Colour Quality Scale, Memory Colour Indices and most importantly (considering its recent rise to prominance IES TM-30-15/18).

==Suggest merge January 2019==

[[Color rendering capacity]] covers substantially the same subject matter as this article. Any unique material from that article could be merged here to make a more comprehensive discussion. --[[User:Wtshymanski|Wtshymanski]] ([[User talk:Wtshymanski|talk]]) 18:26, 18 January 2019 (UTC)
