Brief Introduction
Beta 2.5 |
The standard portable M4 LED has 1750 Ansi lumens, a contrast of 5000:1 and an HDTV 1920 x 1080 resolution. Manufacturer CooLux specifies a service life of 30,000 hours, which is over 20.5 years if enjoyed for four hours a day. 1750 Ansi lumens ensure that a picture width of 425 cm is also possible. However, if room light is available, the picture should be max. 283 cm wide. Thanks to the built-in 20000mAh battery, no power supply is required, allowing the projector to be set up quickly and flexibly. In addition, the Bluetooth option is a useful addition to the projector, especially for wireless audio transmission. The model is also Full HD 1080P compatible.
