Chapter 5 Maintenance — Maintenance/replacement

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 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, because it may cause malfunction of the projector.

If the runtime of all the four lamp units exceeds 3 000 hours, the power will be switched off after approximately 10 minutes.
