The new Mitsubishi XL1550U business projector is one of two interesting, sibling projectors from Mitsubishi. The other is the more powerful XL2550U. This review will focus on the XL1550U, but I will comment occasionally on the XL2550U projector where it differs from the lower cost XL1550U projector. I only had the XL1550 LCD projector to work with. All subjective comments about the XL2550 projector are based on the spec differences, and other factors, but again, I did not have one in here for testing.
Overall, these Mitsubishi projectors would have to be considered moderately bright, portable projectors. They are neither very small (ultra-portable, micro-portable, pico portable), nor very light at 10.4 pounds (4.7 kg). The XL1550U claims 3100 lumens, while the brighter Mitsubishi XL2550U claims 4000 lumens. In reality, Mitsubishi refers to them as install projectors, and they have the features to match. Still, they are not so large or heavy to preclude them from being used for a lot of local portable presentations, being moved from room to room, or building to building. It's far less likely that people will want to use them if traveling by plane, just too bulky. Despite Mitsubishi promoting them as Installation Projectors in its brochures, it does include a carry case with both models.
Two notable features come to mind with these two projectors. First, is that they offer interchangeable lenses, and are relatively inexpensive among projectors that do offer lens options. The other feature is long lamp life (in low power modes).
