Why hasn't the brightness changed noticeably after I replaced it with a new bulb?
Projection brightness is not only related to the lamp, but also to the machine configuration, optical path components, and lens aging.
How to extend the life of light bulbs as much as possible?
1: Use ECO mode to reduce lamp consumption.
2: Do not exceed 4 hours each time.
3: Do not disconnect the power supply during use.
4: Clean the dust regularly and replace the filter.
Why does my newly replaced projector bulb display that it has already been used?
