Doing some online checking I found the following:
PT-AE8000 Lumen Output and Color Temp with 100 IRE Field (mid zoom)
Cinema 1 643 @ 7053
Cinema 2 1175 @ 8554
Game 1245 @ 10199
Normal 1285 @ 9746
Dynamic 1898 @ 7757, 1255 lumens with AI off
Rec. 709 622 @ 6695
D-Cinema 643 @ 6437

Post Calibration: Best Mode = REC 709 The PT-AE8000 measured 602 lumens calibrated in “best” mode.
Light output. The spec on the AE8000 is 2400 lumens, which is a 20% increase over the AE7000's 2000-lumen rating. The spec understates the brightness differences we see on our test samples. Here, in table form, are the lumen readings we saw on our AE8000 compared to our AE7000 readings from last year:
Mode AE7000 AE8000
Cinema 1 526 822
Cinema 2 1089 1612
Game 1204 1673
Normal 1300 1752
Dynamic 1685 2471
Rec. 709 592 821
D-Cinema 544 872
We connected the AE8000U to Ray's calibration setup, which consisted of a Windows laptop running SpectraCal's calibration software, controlling both a calibrated signal pattern generator and my C6 meter. In order to check our work, we also had on hand a Konica Minolta CS-200. Out of the box and in the AE8000U's "Rec 709" image preset, we measured a solid 10.2 foot-lamberts from the projector. It should be noted that, because I employ an acoustically transparent screen, light readings are somewhat diminished - on average, between 15 and 20 percent - so on a non-acoustically transparent screen, you could reasonably expect a light output of, say, around 12 foot-lamberts. Again, not bad for a 120-inch screen.
Some contradiction in these 3 so I am leaning towards ceiling mounting the projector instead of back in the closet. Definitely want a bright image and would like to do a 140" wide 2.35:1 acoustically transparent screen, so maybe 17 feet back from the screen on the ceiling would work better than 20 feet back in a closet.
