*Brightness is the main issue, since the larger the dome, the larger the surface area the light from the projector must cover.

**Provided for comparison purposes with other systems. Actual brightness with a fisheye lens is significantly less due to not projecting the whole video rectangle and differing lens properties. Please see any of our other models if you need a brighter system.

***The rugged transit case has built in wheels and an extendable handle for easy transport on flat surfaces.
