cause it to burst. Be careful when |
handling the lamp. |
Lamp unit replacement period
The lamp is a consumable product. Even when the full life of the bulb has not been exhausted, the brightness of the light will gradually decline. Therefore periodic replacement of the lamp is necessary.
The intended lamp replacement interval is 2 000 hours, but it is possible that the lamp may need to be replaced earlier due to variables such as a particular lamp’s characteristics, usage conditions and the installation environment. Early preparation for lamp replacement is encouraged.
