Pixels per degree of sky
4.3 average
Angle of Projection
175 degrees
Base Projector Brightness
3500 Lumens with non-fisheye lens (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 contact us if you may be interested in a brighter system.)
