 NOTE: The lamp life rating for any projector 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 
percent of a lamp sample population to have brightness decrease by 
approximately 50 percent of the rated lumens for the specified lamp. The lamp
