The warranty documentation that comes with the Acer K335 offers the standard (for projectors in this class), one year parts and labor warranty coverage for the projector. Although the rather generic projector warranty states there is a 90-day warranty on the lamp, but this is not applicable here as the K335 has not lamp and instead the LED light source is not replaceable. The K335’s LED light source is rated at 20,000 hours, so it’s unlikely that it will be an issue for the life of the projector.
