This fact sheet ddresses key questions about color stability and color shift in LED lighting applications.
Lumen maintenance has dominated discussions about LED lifetime, but color shift is another important performance attribute that can cause an LED lamp or luminaire to fail. The color stability of LEDs varies from product to product, and potentially for the same product used in different applications. Properly communicating about color shift, understanding why and when it can occur, and appropriately monitoring performance can help lead to a successful, long-lived installation.
