Lamp life
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 life rating is not guaranteed
in any way. The actual operating life span of a projector lamp will vary
according to operating conditions and usage patterns. Usage of a
projector in stressful conditions which may include dusty
environments, under high temperatures, many hours per day, and
abrupt powering-off will most likely result in a lamp's shortened
operating life span or possible lamp failure.
