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.
