The equipment of the Epson USA Pro L20000UNL projector includes 20000 ANSI lumens, a contrast of 2500000:1 with a WUXGA 1920 x 1200 display. The manufacturer lists the lifespan for this model at 20000 hours – calculating to 13.7 years at four hours of use per day. To meet a wide variety of installation conditions, the projector offers the option of using different interchangeable lenses. Verifying the respective distances is easily possible via the Projector Calculator. Regarding projection size, the value of 20000 ANSI lumens allows for an image width of up to 1437 cm in darkened environments. In rooms with ambient light, the image width should be correspondingly reduced to a maximum of 958 cm. In terms of video signals, the device processes resolutions up to Full HD 1080P and 4K. Regarding professional networking, the device offers a classic RJ45 LAN port for control alongside HDBaseT for the lossless transmission of picture and sound over long distances. Since entering the market in 2020, production has been discontinued; the manufacturer no longer actively offers the model. In our projector directory, the device still generates high interest.
