NEC lists NP-PX1005QL as a 10,000 lumens projector. Just how close did theNP-PX1005QL come to hitting its target 10,000 lumens? As always, I took 3-4 readings about 15-20% out from the center of the lens which usually gives a pretty good approximation of ANSI lumens. At full wide angle I measured the NEC NP-PX1005QL in its brightest picture mode, HIGH-BRIGHT, with the ECO Mode set to OFF.
NEC NP-PX1005QL Brightness: 10,055 Lumens
At wide zoom, High-Bright mode.
The NP-PX1005QL measured 10,055 lumens which was slightly above NEC’s brightness claim. For the seven available modes, I also measured them at mid-zoom since it is common for a projector to be zoomed in a bit when installed.
The high brightness of the PX1005QL really made video, presentations, and images pop even in ambient light. When taking screenshots of my 120″ screen, there was almost no need to completely turn off the room lighting. I only bothered to kill the lights for the test images and the brightness measurements.
The sealed LCD cooling system not only isolates the optics from dust and eliminates the need for filter changes, it also reduces fan noise. The NEC PX1005QL produces 37db in Eco Mode and 42db in high power. While this noise level is in line with other the large venue, high brightness projectors, I have tested quieter units. For example, Epson quotes its 15,000 lumens Pro L1755UNL’s noise level at 30db in its Quiet mode. However, relative to the amount of brightness the PX1005QL can output, it is still a pretty quiet projector.
