Tags: what is CRI in lighting, colour rendering index

CRI, or Colour Rendering Index, is a measure of how accurately a light source shows the true colours of objects compared to natural daylight. It's rated on a scale from 0 to 100 — the higher the number, the more true-to-life colours appear. A CRI of 90 or above is considered excellent and is recommended for homes, while cheap lighting often sits at 70–80, making colours look dull, washed out, or slightly off. CRI matters because it decides whether your home actually looks the way it was designed to.
