■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 it regularly. The estimated duration before replacement is 2 000 hours. However, this may be 

shortened depending on individual lamp characteristics, usage conditions, and the installation environment. 

Therefore, it is strongly recommended that a replacement lamp unit be prepared. The unit can damage the 

projector if it has not been replaced after 2 000 hours of usage. Thus, the lamp automatically turns off after 

approximately ten minutes.

If the cumulative operating time of all 4 lamp unit bulbs exceeds 2 000 hours, the power will be switch off after 

about 10 minutes.
