10.2. When to replace the Lamp Unit
The lamp units are consumable parts. The lamp brightness decreases gradually as the cumulative operating time increases, so
periodic replacement is necessary. The replacement guideline is 2 000 hours, although the lamp may become dead (will not light)
before 2 000 hours is reached depending on the characteristics of individual lamps and other factors such as the operating
conditions and the installation environment. Therefore, it is recommended for the user to keep a spare lamp unit.
The risk of the lamp bursting increases after 2 000 hours of operation, so the lamp unit turns off automatically.
