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 a sample set of lamps is 2000 hours and their brightness is rated at 1100 lumens, then after 2000 hours 50% of the lamps will still be brighter than 550 lumens.
