i have been using the projector calculator at Projector Central and have been considering the Optoma HD25,HD25e, and BenQ 1070. Right now I have a Viewsonic PLED-W500. I have an 85" Da-Lite CinemaVision 1.3 gain fixed screen in my living room. My living room is open with my kitchen, which has some windows that I dont block out. Generally poor lighting during daytime, fine during nighttime

I got these fL numbers from the calculator:
HD25e: 85fL, 9'3" distance
HD25: 61fL, 9'3" distance
w1070: 49fL, 9'3 distance
PLED-W500 (current): 27fL, 8'8" distance

I find my current projector only usable during nighttime and early morning. I am assuming the calculator goes by advertised lumens. If I were to run the HD25/1070 in Eco mode (say 60% of advertised lumens), it would still put me at 40-60fL. I

Is there such a thing as too much feet/lumen?

During the daytime, there is almost no such thing as 'to much light'. But, at night there certainly is. I run the W1070 in low brightness on theater mode using a 161" screen and it is plenty bright enough. So, about 15-18 lumens per square foot is more than sufficient for after dark viewing.

But, during the day, the only hope you have for any usable image is by putting up lots of lumens. I think you would be pretty happy with the W1070 or the 25LV in your setup.

IN HIS REVIEW OF THE BENQ W7000, BILL LIVOLSI WROTE: Our measurements indicate that 3D mode puts out 1100 lumens on our test sample, and BenQ's 3D glasses transmit 28% of the total light they receive. If you have a 1.0-gain screen, that works out to 11 fL on a 100" diagonal screen. I'VE GOT A 120" SCREEN. DO THE MATH AND THAT SEEMS TO KNOCK THE fL down to 7.5. IS THAT GOING TO BE GOOD ENOUGH IN A VERY LOW AMBIENT LIGHT? IS IT EVEN ENOUGH IN A TOTALLY DARK ROOM?
