Attention: Lamp Life is a measure of brightness degradation only, and is not a specification for the time it takes a lamp to fail and cease light output. Lamp Life is defined as the time it takes for more than 50% of a lamp sample population to have brightness decrease by approximately 50% of the rated lumens for the specified lamp. For example, if the defined life of your lamp is 1500 hours and its brightness is rated at 2650 lumens, then there is a 50% chance that over 1500 hours of run time, your lamp will have decreased its brightness by 50% to approximately 1325 lumens.
