This product is a high-brightness, high-resolution projector used in large-scale exhibitions, concert halls, outdoor signage, and the like. To achieve various kinds of image projection in a harsh environment surrounded by dust, dirt and smoke, we designed the positions of the lens and the ventilation port to allow you to freely adjust the projection direction or install multiple projectors. In addition, the handle frame allows for safer, easier installations and protects the unit. Its understated yet powerful design achieves the freedom in use and installation that projector pros desire.
