The basic data of the Epson USA Pro L20000UNL includes 20000 ANSI lumens, a resolution of WUXGA 1920 x 1200 as well as a contrast of 2500000:1. The manufacturer lists the lifespan for this model at 20000 hours. With four hours of daily operation, this corresponds to a period of 13.7 years. The specifications identify the device as a model with an interchangeable lens option. Matching optional optics allow for exact adaptation to the required image size and projection distance, which can be calculated directly with the Lens Calculator. Looking at practical performance, up to 1437 cm can be illuminated with 20000 ANSI lumens in dark environments. Once daylight is in the room, the image should ideally be no wider than 958 cm. For media input, video signals up to 1080P and 4K are supported. The model is perfectly equipped for complex installations: In addition to the RJ45 jack for network administration, an HDBaseT port is available, transporting high-resolution AV signals over a single Cat cable. Since entering the market in 2020, production has been discontinued; the manufacturer no longer actively offers the model. This model continues to hold a solid place in our database search queries.
