■ 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. If the lamp is not replaced
after 2 000 hours of use, a malfunction will occur and the projector will automatically switch off after
approximately ten minutes.
Over 1 800 hours
Over 2 000 hours
Note
z The 2 000 hour usage period is a rough estimate and is not guaranteed.
