The BenQ LU935ST has a long-lasting laser light source that is rated for 200,000 hours. This means that if you use the projector for 8 hours a day, it will last for over 22 years. However, the lifespan of the laser light source will also depend on other factors, such as the ambient temperature and the type of content that you are projecting.

Here are some tips for extending the lifespan of your BenQ LU935ST projector:

  • Avoid using the projector in extreme temperatures. The ideal operating temperature for the projector is 50-85 degrees Fahrenheit.
  • Avoid using the projector in dusty environments. Dust can damage the projector’s internal components.
  • Have the projector serviced regularly. A qualified technician can clean and inspect the projector for any potential problems.

By following these tips, you can help to extend the lifespan of your BenQ LU935ST projector.

Here are some other factors that can affect the lifespan of your projector:

  • The type of projector: Some projectors are designed for more frequent use than others.
  • The environment: Projectors that are used in dusty or humid environments will wear out more quickly.
  • The maintenance schedule: Projectors that are not properly maintained will wear out more quickly.

If you are concerned about the lifespan of your projector, you can purchase an extended warranty. An extended warranty will cover the cost of repairs or replacement if the projector fails within a certain period of time.
