It was late last night and I was tired but since the projector was warmed up I decided to run a quick test of the lumen output of my AR100U, partially because I know there are people interested in this projector and for my own curiosity. Rather than doing a comprehensive test using the required 9 point readings I opted for coderguy's method of 3 point measurements - center, lower left and upper right corners of the screen. I used an inexpensive digital illuminance meter I purchased several months ago. The AR100U has 7 picture modes which significantly change the light output.
As listed in the owner's manual:
[NORMAL] - For a general image.
[DYNAMIC] - For viewing at high brightness.
[GAME] - For use with games.
[SPORTS] - For sports program.
[REC709] - For HDTV standard (ITU-R BT.709) color temperature 6500K at the default setting.
[CINEMA 1] - Tuned by top Hollywood colorists for watching a movie with smooth image quality.
[VIVID CINEMA] - For use with a high luminance, clear picture mode.
The readings were taken using the LUX scale and converted to lumens and ft-L.
Screen size 119" - aspect ratio 16:9. The screen area is 41 square feet.
The distance from projector to screen 13 feet 7 inches.
This projector has NOT been calibrated. The bulb has 80 hours of use.
Below are the converted readings in order of brightness (ECO mode):
[DYNAMIC] - 1974 lumens (52.9 ft-L)
[SPORTS] - 1836 lumens (49.3 ft-L)
[NORMAL] - 1642 lumens (44.1 ft-L)
[GAME] - 1578 lumens (42.3 ft-L)
[VIVID CINEMA] - 1417 lumens (38.0 ft-L)
[CINEMA 1] - 804 lumens (21.6 ft-L)
[REC709] - 777 lumens (20.8 ft-L)
Since my measurement method was less than ideal just take these numbers as a gauge of what this projector is capable of.

EDIT: I recently discovered that what I had thought was a 120" screen was in fact 119". Because screen size has a significant bearing on lumen and foot lambert calculations I have corrected the numbers here.
