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 2 500 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 2 500 hours of use, a malfunction will occur and the projector will automatically switch off after approximately ten minutes.
