The WL7200U is rated at 5500 lumens. While many projectors do not come close to their rated output in our testing, the WL7200U’s measurements justified that rating. In Presentation, Standard or User modes (all equally bright), we measured 5320 lumens at full wide zoom. At full telephoto zoom, output dropped to 3562 lumens and at mid zoom, where all additional measurements were made, the output was 4710 lumens for the above modes. Auto mode, which automatically sets an optimal color balance based on the input signal, also came in at 4710 lumens. Theater mode, which provided the best overall color and contrast, dropped to 4190 lumens, still very bright. sRGB mode yielded 4190 lumens as well. There are two additional modes, Clear Base and Blue Base, which are intended to be used for viewing X-ray film. Clear Base came in at 2860 lumens, while Blue Base was at 2960 lumens. It's likely that in most cases, unless the most accurate color is required, Auto or Presentation modes will be the preferred setting.
Dropping the lamp into Low brightness mode resulted in a significant drop of 31.4%, but still provided 3230 lumens in any of the brightest modes. With anything but the largest venues and as long as there was some light control in the room, using Low lamp mode will be a viable option. This would allow the presenter to save on power usage, as well as obtain an additional 1000 hours of lamp life.
