Laser-powered 4K home theater projector

The Nebula Cosmos Laser 4K delivers true 4K UHD resolution with HDR 10 support and a laser light source rated at 2000 to 2499 lumens. Its Intelligent Environment Adaptation technology analyses the room to automatically handle focus, keystone correction and screen fit. Android TV 10.0 provides access to 7000+ apps and 400000+ movies and episodes. Integrated dual 5W tweeters and dual 10W speakers create a 3D soundscape with Dolby Audio.

Sustained brightness and automated setup

Laser illumination maintains consistent output over long viewing sessions without the dimming cycle typical of lamp-based units. The IEA system continuously monitors the environment, preserving geometry and focus if the projector is moved or lighting conditions change. Android TV 10.0 runs streaming apps directly on the device, avoiding the thermal throttle that can affect external dongles during extended playback.

Quiet operation with portable convenience

The laser engine runs cooler than traditional lamps, allowing the cooling system to operate at low noise levels during typical home theater use. An ergonomic handle enables easy relocation between rooms or outdoor spaces without recalibration delays. Eye-guard technology automatically dims the beam when an object enters the light path, reducing power draw and enhancing safety during family viewing.
