Striking the Perfect Balance
While we strive for higher CRI scores to achieve impeccable colour rendering, there is a trade-off to consider. The higher the CRI of a light source, the lower its output will be. The good news is that advancements in lighting technology have significantly narrowed this gap. Today, the difference in output between CRI<70 and CRI<90 is approximately 10%, making high CRI lighting more accessible and practical for various applications.
CRI in Different Environments
The ideal CRI value depends on the specific application and environment. In office settings, where colour precision is crucial for tasks and productivity, CRI<80 is typically considered acceptable. However, as we delve into the realm of retail, where visual merchandising and customer experiences reign supreme, a higher CRI<90 is preferred. This ensures that products look their best, encouraging customers to linger and explore.
In environments such as car parks and warehouses, they prioritise functionality and efficiency over colour precision. For these applications, a CRI<70 or higher is considered adequate, as the primary concern lies in providing ample illumination for safety and convenience.
