How to Find CRI on Light Bulbs?

The CRI of a light bulb can usually be found on its packaging, specification sheet, product label, test report, or manufacturer’s technical data. It may appear as “CRI,” “Ra,” or a value such as CRI 80, CRI 90, or Ra ≥90. When no rating is published, color-rendering performance cannot be confirmed from wattage, lumens, or color temperature alone.
