K138STi Pico Projector

The K138STi is a great combination of a detailed HD picture with an 800 lumen brightness combined with a short throw distance making a large image possible even in a tight space. The short throw lens really sets it apart making it possible to get a large image in a small meeting room and avoid having the presenter cast a shadow on the screen. All combined in a small mini projector that weighs 750grams.
