What is a lumen?

This is a measure of brightness.  The more lumens, the brighter.  This is important because you can view the image without needing to turn out the lights in the office or boardroom.

What is a 2x zoom on a projector?

The 2x zoom allows a person to fill a 60-inch screen from either 5 or 10 ft from the screen.  This is important because if a person is in a small office, all can still see the projector.  Or, if it is positioned in a boardroom there will not be a problem with the image spilling off the screen.

What is keystone correction?

If a projector is positioned above, below or to the sides of a screen, the image will look wider on one side and the image will look distorted.  The keystone correction uses software to adjust for this by compressing the wider side.  The listed degrees in the specifications show how far from off center this can be adjusted for.

How many decibels are the projectors?

Approximately 38.  There is a low noise mode that reduces the brightness of the image and decibels by about 15%.

Can the projectors be mounted to a ceiling?

Chief Manufacturing at http://www.chiefmfg.com produces mounting brackets for our projectors.

Here are the mount part numbers for our projectors.

Model:                   Bracket #:
Casio XJ-350      LCDA-215C
Casio XJ-360      RPA-116
Casio XJ-450      RPA-067
Casio XJ-560      RPA-067

The XJ-450 is a invertible projector, so the mount is on the bottom of the projector and the projector gets inverted on the ceiling. The XJ-350 is a non-invertible projector, but does have negative keystone correction, so the mount is more like a wrap around shelf. They both are mounted on 1 1/2" NPT pipes from the ceiling.
