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 4 000 hours, but the lamp may go
off before reaching to 4 000 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 4 000 hours has elapsed, the lamp turns off automatically after
approximately 10 minutes, as it may cause malfunction of the projector.
