FAQs
Browse all related FAQsDo I need to replace the LED lamp of the projector?
There is no need to replace it during the normal usage lifetime of the projector. Because the projector uses an LED light source instead of a lamp, it can last for about 20,000~30,000 hours so there is no need to change it during the normal usage lifetime of the projector. If you want to change the lamp, please notice that LED replacement is not user-serviceable, please contact the service center to replace it.

Yes, you can absolutely use any projector for movie, TV watching and any big-screen entertainment needs, and we also recommend dedicated home cinema projectors for better movie enjoyment.
