The W600 is rated at 2600 lumens. Unlike many projector manufacturers, BenQ’s lumen ratings are usually conservative and the W600 was no exception. Using the Standard lamp setting, in Dynamic image mode (the brightest), we measured 2964 lumens at mid-zoom range. There’s not much zoom range with a 1.15X zoom, so the output did not vary much throughout the zoom range. At full wide zoom (again in Dynamic mode), we got 3016 lumens, but going to full telephoto zoom made a greater difference, dropping to 2788 lumens. All further measurements were taken at the mid-zoom point. Using Standard mode, the output dropped significantly to 2103 lumens. Cinema mode, which we used for video evaluation, was the lowest at 1552 lumens. Finally, sRGB mode came in at 2124 lumens. It should be noted here that all of the measurements were made with Brilliant Color turned on. Turning off Brilliant Color results in a drop in output of almost 35%. Changing the lamp into Eco mode drops the lumen output by 22%.
