The basic data of the Ankaka W20830 includes 315 ANSI lumens, a resolution of WXGA 1280 x 768 as well as a contrast of 1000:1. The built-in LED technology features a light source lifespan of 20000 hours. Daily use of 4 hours makes an operational lifespan of over 13.7 years possible. To ensure objective comparability, an approximate ANSI lumen value was calculated based on the lumen specifications. A look at the light output reveals: The 315 ANSI lumens are sufficient to illuminate an image width of up to 180 cm in darkened rooms. If room light is present, we recommend not exceeding a maximum width of 120 cm. For media input, video signals up to 1080P are supported. Also on board is a local media player that allows reading and playing content directly from storage media. This model dates back to 2013 and is no longer part of Ankaka's current product range.
