When to replace the lamp unit
The lamp unit is a consumable component. Brightness decreases according to duration of usage, so periodical replacement
of the lamp unit is necessary. A rough estimate for the usage period is 4 000 hours, but depending on the characteristics of
individual lamps, usage conditions, periods of continuous use, and environmental conditions etc., the lamp may cease to
illuminate prior to reaching 4 000 hours of use. It is recommended that you prepare a spare lamp unit in advance.
As the risk of the lamp to cracking increases after 4 000 hours the lamp automatically turns off.

When the lamps are turned on and off frequently, the lamp replacement cycle is shortened. The usage environment affects
the lamp replacement cycle.
