Major League light cannon!
As you look at these high lumen numbers above, remember that they are with the zoom lens set for mid-point. If you place your projector at the closest position to fill your screen, you will get another boost - with Dynamic topping out at 2900, roughly 15% above their 2500 lumen claim
Placement distance doesn't though make a huge difference. Even at the other extreme: 16 feet from a 100" screen instead of 9 feet 10 inches, the Epson still manages 2453 measured lumens. That's only a reduction of 15%, a modest amount for a 1.6:1 zoom.
You can expect that same 15% drop between wide angle and telephoto to be the same, no matter what mode you select.
I should mention at this point, that there are three additional modes not shown in this table. Two are 3D modes which we don't measure, since other factors besides raw lumens determine how bright a 3D image looks. The third is interesting - it's Auto mode, which relies on the light sensor on the top of the projector. Mike did measure it, but realize, when he's running is tests, the room is fully dark, so no way to accurately see how much the brightness varies as the ambient light increases.
Mike measured Auto mode as 1559 in a dark room with the lamp in Eco mode. I suspect that it was the projector that decided on Eco mode, because the room was dark, but Mike hasn't yet clarified that point. That does make sense, since even 1500+ lumens is a whole lot of brightness in a dark room, enough to easily fill a 150" diagonal screen.
I've posted on the same table above, the color temperature for white for each of the modes.
This Epson has 3 lamp modes - High, Medium and Eco. As I reported in the Special Features section, switching from High to Medium results in a drop of almost a perfect 10%, and going all the way to Eco, results in a much greater drop of almost 30%. I like the Medium setting, you give up only the slightest brightness, but the fan runs noticeably quieter.
