Brightness. It is rare when we test a projector that exceeds its brightness specification, and it is unheard of when our test measurements are 25% higher than specified. But that is exactly what we found with our test unit. NEC specifies brightness at 3,500 lumens, but in the High Bright setting, we measured light output at 4,355 lumens. Here are the other readings:
Color Brightness. The M353WS's color brightness measured 62% of its white brightness in Natural mode, which is the highest reading among the various presets. High Bright measured 29%, Presentation was 45%, and Movie, 57%.
Brightness Uniformity. As with most short-throw projectors, brightness uniformity was a bit low at 71%. However, the brightness increased smoothly from the top to the bottom of the image, and the difference was unnoticeable for video projections although some viewers might detect the difference on data projections with lots of white space.
Eco Modes. There seems to be a trend toward multiple Eco settings, and the M353WS is no exception. Normal Eco reduces brightness by 18% and Full Eco by 43%.
Audio. The M353WS is head and shoulders above its competition when it comes to audio performance. Unlike its 10-watt brethren, the M353WS sports a 20-watt speaker that can easily handle a medium-sized room. It is also buzz- and rattle-free over its entire range.
Input Lag. While gaming may not be the prime application for the M353WS, it has a Bodnar lag reading of only 33.2 milliseconds which means it will keep up with fast-changing source material.
Fan Noise. One advantage of the M353WS's relatively large case size is that it suppresses fan noise. The fan noise is also restricted to the low- and mid-frequency range, so it is not intrusive even for viewers sitting next to the projector. At altitudes over 5,500 feet, you must set the fan to high altitude mode which increases fan speed and noise substantially.
Lamp Life. The lamp in the M353WS is rated at 5,000 hours for full brightness. In Eco modes, lamp life is extended to 8,000 hours, and fan noise is reduced. The replacement lamp on this model is listed at $299 from NEC.
