How to extend lamp life Bulbs in a long-term high-temperature environment will accelerate the aging of the bulb, brightness decline, and cause early damage to the bulb. Clean the dust of the air filter regularly to keep the heat dissipation smooth and prevent the bulb from working at too high a temperature due to obstruction of heat dissipation.Turn off the projector when not in use to prevent the lamp from continuing to heat up, suggested no more than 4 hours per use.Wait for the fan to stop rotating after turning off the projector and then unplug the power off to allow the lamp to get sufficient heat dissipation.
