|Base Projector Brightness
||2200 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 see our other models if you need a brighter system.)
||3900:1 (Actual measured value with fisheye lens.)

Overall, I would rate Digitalis Education and [my Digitarium] Alpha 2 system as a +12 on a ten point scale. The service is second to none. It is the most intuitive system to operate of any I have tested (Digital Starlab, mirror systems, others which cost several times the cost of the Alpha 2) The product is very robust.
