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.
