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 3 000 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 kept.
As the risk of the lamp to cracking increases after 3 000 hours
