Summary
- The CRI value measures the colour rendering of light more broadly than the Ra value
- High CRI value improves the natural colour rendering of lighting
- Ra value does not take into account all colour tones, such as skin tones
- LedStore reports the actual CRI values of its products
- Professionals appreciate high CRI in working environments
The article seems to completely contradict the Wikipedia article which indicates that the terms CRI and CIE Ra are synonymous unless it specifically references that it's CRI R96a (which is non standard). So, in stark contrast to what's stated in the article, when any lighting product refers to CRI, it will indeed be the same as the poor quality Ra metric, unless it makes reference to R96a or R9.
