The technical data of the Epson EH LS10000 includes 1500 ANSI lumens, a contrast of 10000000:1 as well as a UHD (4K2K) 3840 x 2160 display. This is a laser projector with a light source designed to last for 30000 hours – calculating to 20.5 years at four hours of use per day. To facilitate room installation, the device is equipped with mechanical lens shift and additional keystone correction. Precise setup distances can be determined in the Projector Calculator. A look at the light output reveals: The 1500 ANSI lumens are sufficient to illuminate an image width of up to 393 cm in darkened rooms. If room light is present, we recommend not exceeding a maximum width of 262 cm. For media input, video signals up to 1080P and 4K as well as 3D are supported, meaning standard Blu-ray formats are processed effortlessly. For integration into professional environments, an RJ45 connection is available for network control and remote maintenance. A look at the data sheet confirms a very subtle fan noise for the projector at just 28 decibels. Since entering the market in 2014, production has been discontinued; the manufacturer no longer actively offers the model. In our projector directory, the device still generates high interest.
