When the lamp is consumed, the brightness may decrease over time. 3 000 hours of use is the replacing 

time as a rough guide, and that might be shortened by the usage conditions, characteristics of the lamp unit 

or environmental conditions. You can find the duration of usage time by checking 

LAMP RUNTIME in the 

PROJECTOR SETUP menu. Do not use a lamp unit over 3 000 hours. Failure to observe this may result in 

explosion of the lamp.
