Room planner

See each one in your sim room.

The planner draws each unit to scale with your room and your swing: where it mounts, the throw it needs, and whether your shadow crosses the light. Put in your room once, then switch units in the planner to compare.

Better for LK936ST

  • Showroom

    5,100 ANSI lumens holds up with the lights on, and lens shift squares the image without keystone. The laser is rated 20,000 hours, so there is no lamp to maintain for the practical life of the room.

  • Performance Seeker

    Brightness and color accuracy hold up to bright-room data review; the right pick when ambient light is real.
