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 2 500 hours*1, but the lamp may go off before 2 500 hours*1 has elapsed depending on individual lamp characteristics, 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 2 500 hours*1 has elapsed, the lamp turns off automatically after approximately 10 minutes, as it will cause malfunction of the projector.

If the runtime of both of two lamp unit bulbs exceeds 2 500 hours*1, the power will be switch off after approximately 10 minutes.
