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.

NOTE: Before you turn on the projector again, wait for 60 seconds to allow the 

internal temperature to stabilize. The projector will take a longer time to turn on 

if you try to power on immediately. Its cooling fan will run at full speed for about 

30 seconds to stabilize the internal temperature.
