An LED lifespan of 30000 hours is noted in the data sheet for this model, which translates to 20.5 years with 4 hours of daily use. Regarding projection size, the value of 330 ANSI lumens allows for an image width of up to 185 cm in darkened environments. In rooms with ambient light, the image width should be correspondingly reduced to a maximum 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. Since the projector supports Miracast and Airplay screen mirroring, video signals can also be streamed wirelessly from the end device.
