NOTE: The LED life rating for any projector is a measure of

brightness degradation only, and is not a specification for the time it

takes a LED to fail and cease light output. LED life is defined as the

time it takes for more than 50 percent of a LED sample population

to have brightness decrease by approximately 50 percent of the

rated lumens for the specified LED. The LED life rating is not

guaranteed in any way. The actual operating life span of a projector

LED 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 LED’s shortened

operating life span or possible LED failure.
