Colour Rendering CRI 90+

Quality of Light, Measured by Colour Rendering Index

The Colour Rendering Index (CRI) is the measure of how well a light reproduces colours on a scale of 1-100.

So, in your art gallery you should aim for your lighting to have a minimum CRI of 90.

Lights nowadays typically have a CRI of 70-80 – while this is relatively high, it is not high enough if you really want to show authentic colour to your fellow art lovers and patrons.
