The projector EAZZE D1R Cube by Aurzen utilizes LCD technology and, according to the spec sheet, achieves 330 ANSI lumens, a contrast of 15000:1 at a resolution of HDTV 1920 x 1080. The built-in LED technology features a light source lifespan of 30000 hours, covering an estimated 20.5 years based on a 4-hour daily runtime. A look at the light output reveals: The 330 ANSI lumens are sufficient to illuminate an image width of up to 185 cm in darkened rooms. If room light is present, we recommend not exceeding a maximum width of 123 cm. Regarding signal processing, the model is compatible with incoming 1080P content. Furthermore, the model is Bluetooth-enabled, allowing audio signals to be sent wirelessly to external speakers. Thanks to support for Miracast and Airplay, screen content can also be cast wirelessly from a smartphone, tablet, or PC to the screen.
