• Lower CRI lights(60 - 79) tend to distort object colors, but can be used for task lighting where color accuracy is less important.

In summary, consider both color temperature and CRI to ensure:

• The light creates the mood and atmosphere you want

•Colors of objects, decor and people's faces appear vibrant and natural under your chosen illumination.

So,striving for higher CRI lighting, especially for general ambiance, will optimize the visual experience within your space.
