Highest Brightness Under 300 USD

Brightness is the core of a projector. As a professional projector expert, we suggest to choose high lumens projectors even if they are a little more expensive than others. Because it not only will offer better viewing experience, but also better projection your eyes and health.

WiMiUS has been improving the brightness of our new models. With the joint efforts of more than 100 top domestic projector experts, we developed this brightest K8 Full HD wifi bluetooth projector. It is much brighter than 100% other projectors under 300USD. Even with some light on, the images are still watchable. In dark room, it’s comparable to real 4K cinema.

【50-300 Inches Giant Projection Size】

With 1.5-10m projection distance, it can project 50-300 inche images.The recommended projection distance is 3m with 90 inches screen. With 3.3m, you could get 100 inches screen.To get images larger, we need to take the projector further to the screen.

15000:1 Contrast Ratio

Contrast has a very critical effect on visual effects. Generally speaking, the greater the contrast, the clearer, brighter and more

eye-catching of the image; while the lower the contrast, the whole

picture will be gray. Our K8 video projector has the greatest contrast ratio 15000:1 (real), it will bring you very vivid and sharp images.

Native 1080 Support 4K

Generally, the higher the resolution of the projector, the more pixels it contains, and the clearer the image will be.Currently there are 2 common resolutions, native 1080P and 1080P supported. Native 1080P resolution contains 1920*1080 pixels, while for 1080P supported projector, they only contain 1280*720 pixels or less.From this number, we could know the difference well.Our HD projector is real native 1080P resolution, and when connected with smartphone, it can display 4K videos. The image has no difference compared with 1080P TV.

Full Sealed 200,000 Hours LED Lamp

To reduce dust enter into the projector, we adopted full sealed design,

which can reduce dust entering rate by 50%. Also for the best model, we adopted best led lamp, which can last as long as 200,000 hours. If you use it 3 hours one day, it can be used for more than 182 years.

Built-in Bass-Reflex sound system

It was built in dual 10W stereo speakers. The sound quality is the best

of all projectors. In normal size living room or bedroom, no external

speakers needed.

Connect Firestick to Play Netflix, Hulu, Disney

Because of HDCP limit, when connected with smartphone, it can’t support netflix, hulu, disney. We need to plug an fire tv stick or chromecast to the projector, then we could enjoy these apps.
