The duration of projector lamps will depend on the materials and quality of construction. The difference varies from 6,000 to 30,000+ hours of watching time. If we do the math, 6,000 hours of watching time mean that you can watch four hours of content daily for more than three years. The most durable projector lamps will last over a decade. However, it is important to take good care of these components, as well as the device overall. You shouldn’t drop the projector or bump it against the wall, and you should wipe the dust regularly. With proper maintenance and shutting off the device when not in use, you can extend the lamp’s lifespan significantly.
