CRI or Ra bandColour rendering meaningPlanning useBoundary
Below 70Weak colour renderingOnly for non-critical utility contexts where colour judgement is not important.Do not use as a default for occupied task areas.
70-79Basic colour renderingMay be acceptable for simple circulation or back-of-house lighting.Check task expectations and local requirements before relying on it.
80-89General colour renderingCommon planning band for many residential and office tasks.Still check glare, CCT, illuminance and surface colour.
90-94High colour renderingUseful for retail, food, artwork, grooming and colour-sensitive tasks.Higher CRI can reduce efficacy; compare maintained output as well.
95 and aboveVery high colour renderingSpecialist colour assessment or display contexts.Not a substitute for task-specific lighting design or measurement.
