When to replace the lamp unit
The lamp unit is a consumable component. Since its brightness gradually decreases over time, it is necessary to replace the lamp unit
regularly. The estimated duration before replacement is 3 000 hours, but the lamp may go off before reaching to 3 000 hours, depending on
the characteristics of the individual lamp, usage conditions, and the installation environment. It is recommended that the Replacement Lamp
Unit be prepared earlier.
If you continue to use the lamp unit after 3 000 hours has elapsed, the lamp turns off automatically after approximately 10 minutes, as it may
cause malfunction of the projector.
