Rated Average Life

The rated average life of a lighting source is an important measure that designates how long a light source is expected to last on average. This figure is calculated by taking the total amount of hours a light source has been tested for and dividing it by the total number of sources that have failed during that same time period.

It’s important to note that this rating does not necessarily reflect the exact amount of time a particular light fixture will last as there are multiple factors at play including usage, environment, and installation quality.
