Before I get into a lot of measurements and numbers, let's talk practical. This projector, fully calibrated, puts out about 1200 lumens. In a good room, that should provide respectable brightness for a 150" diagonal screen. I've even watched movies, while filling my 124" screen, in low power mode.
This projector doesn't have a mode that's uglier that has significantly more lumens, but that 1200 lumens will certainly still fill a niced sized screen, 100" diagonal and even larger, with modest controlled lighting for sports viewing with friends. I'm talking about my room with 7 down facing led lights in the back half of the room, or with my shutters open just a little in the daytime allowing a controlled amount of daylight to leak in.
Sony rates the VPL-VW1000ES projector as a 2000 lumen projector. We never measured anything close to 2000 lumens, but that surprised me not at all. We don't measure looking for the absolute brightest a projector can do, as that usually isn't a very usable picture. I consider this projector's performance to be in line with expectations, in fact, if anything, I was very pleased to end up with 1200 calibrated lumens.
First are the lumen measurements for each of the preset and user modes. Also included, was the measured color temp for white, for each mode.
