Maintenance Tips
-
Respect full cool-down cycle: Always power off and let the projector cool ~45 minutes before handling the lamp to avoid thermal damage or burns.
-
Avoid frequent on/off use: Extended sessions are better than repeated short cycles, which stress the arc lamp and reduce lifespan.
-
Use Eco/Low Power mode: Reduces heat load and helps extend usable lamp life while maintaining stable brightness.
-
Keep filters and airflow clean: Dirty filters cause overheating—one of the main reasons lamps fail early.
-
Never touch the glass bulb: Oils from skin create hot spots that can weaken quartz and shorten lamp life.
-
Handle gently during installation: The lamp is high-pressure glass; shocks or scratches can cause failure or even breakage.
-
Ensure proper ventilation: Keep vents unobstructed (20–30 cm clearance) to maintain stable operating temperature.
-
Use stable power: A surge protector or UPS helps protect the ignition ballast from voltage spikes.
-
Replace at dimming stage: Do not wait for full failure—replace when brightness drops or “change lamp” warnings appear.
-
Reset lamp timer after replacement: Ensures accurate monitoring of remaining lamp life
