Clear answer, explained.

Higher CRI values result in more vibrant, true-to-life colours. For general commercial applications—such as offices, warehouses, and common areas— CRI 80+ is typically sufficient. However, in spaces where colour accuracy is important—such as retail displays, medical environments, or design studios— CRI 90+ is recommended to enhance visual clarity and presentation.
