The new models can automatically adjust its brightness and drive voltage depending on the environment, which helps preserve the projectors’ lamp life up to 17,000 hours. The EB-U50 and EB-W50 are also built with enhanced durability and resistance with the help of a new electrostatic air filter, which effectively traps dust and chalk particles before they can enter the projector, resulting to longer lasting optical compartment.
