No question about it, the Sony VPL-VW285ES beat its claim of 1500 lumens in just about every mode when lamp is on full power. Of all the modes, Reference was the brightest - although not by much.
When you look at the chart below, please note that we show Reference mode twice, because throughout the performance and calibration pages, we use mid-zoom and full power, unless otherwise noted. That first listing, therefore shows this projector at its absolute brightest. Still at mid-zoom it doesn't lose many lumens!

That makes the VW285ES a light cannon. In a fully darkened room - such as good home theater, you really only need about 450 lumens to fill a 100" diagonal screen with movie theater brightness, so this Sony has power to spare, to tackle more than a minimal amount of ambient light. (HDR content is a bit different.)
