If you have been researching Pico projectors and also have any history with standard projectors in the last few years you might be asking yourself whats the point of a Pico when you consider projectors just a few hundred dollars more have almost 20 times the lumens and their physical size is not really all that much of a deal killer. Well, Picos have one advantage and that is the fact their really really small, but more importantly their lamp will far outlive your needs for the projector.
The manufacturer stated Brightness of the MPro150 is 15 lumens. Our readings in the lab produced 9 lumens. Measurements of the lumens were done with the lights completely off, or at least very little ambient light, the MPro150 produces an aceptable image. However, I can't say it produces a better image than Optoma's LED equivalent.
Reading text on the screen was not bad, but any extended viewing would be very difficult and your small audience would eventually tire. The main use for the projector I have to say would be to use it as a quick, painless method of viewing some pictures from your SmartPhone or laptop. Another use that I think best suits this projector is to use it when traveling. It really is more of a show and tell device. On a camping trip I can see it being kind of nice for an outdoor movie.
