Except where noted, the following measurements were made with the lamp’s Eco setting off. The NP-PE401H is rated at 4000 lumens and, unlike most projectors we review, that rating was spot on based on our testing. The NP-PE401H actually exceeded that rating at full wide zoom, where we measured 4685 lumens in High Bright mode (the brightest). We usually consider anything within 10% below the rated output to be excellent. As the NP-PE401H measured almost 20% higher than its rating, this is exceptional performance. Moreover, when at mid zoom (where all of our additional measurements are taken), the output hit the rated output by coming in at 4013 lumens. Going to full telephoto zoom resulted in a greater drop to 3124 lumens. Also, the NP-PE401H’s High Bright mode is as good as some projectors’ Presentation mode, so you’ll be able to take full advantage of the available lumen output for most presentations.
