They are perfectly matched and compatible with your projector ^^ All projector bulbs are equipped with enclosures instead of bare bulbs. Our bulbs feature an optimized filament design, which helps prevent the machine from overheating or experiencing abnormal temperatures, thereby protecting the bulbs and the projector ^^ When installing a new light bulb, wait for the old bulb in the projector to cool down before replacing it.

And you need to be aware of the connector make sure it connected well ^^ If you have any questions, we will be happy to answer them. Thank you
