Epson PowerLite 93+
May 16, 2012
Brightness and Uniformity -It is always a nice surprise to find a projector that exceeds its brightness specification, and the 93+ beat its 2,600 lumen specification by over 15%. Dynamic mode produced a 3,045 lumen reading, Presentation checked in at 2,410 lumens, and Theatre, Photo, and sRGB all hit the 2,150 lumen mark. That is plenty of light even for a classroom with limited ambient light control, but the real shocker was the brightness uniformity. Our test unit delivered an astounding 99% uniformity . . . the highest uniformity percentage we have ever seen. It is so good that even with an all-white background, there are no detectable hot spots in the image.
Image Size and Offset - The centerline of the 93+'s lens is aligned with the bottom of the image, so tabletop or cart mounting works well. A drop tune would probably be required for a ceiling mount. With a zoom ratio of 1.2:1, the 93+ can put up a 100" image from distances ranging from 9.9-11.9 feet, so placement flexibility is a bit limited.
Lamp Life - Epson uses its E-TORL lamp in the 93+, and that gives it a life of 5,000 hours in normal mode and 6,000 hours in Eco mode. Since Eco mode reduces fan noise and only reduces brightness by about 22%, it may be a good choice for everyday operation.
Auto Iris - An auto iris does help video quality by varying the light level between bright and dim scenes, but it comes at a cost. In low volume passages, the noise of the auto iris is a bit distracting. If this is a problem, the auto iris can be disengaged with only a minor impact on movie enjoyment.
No 3-D - Like most LCD-based projectors, the 93+ cannot handle 3-D content.
Epson has found a niche with their new PowerLite 93+. It may be overkill for some classrooms, but for those that need a wide range of input connectivity and an ability to interface with network protocols, it is a winner. Images are high quality in both data and video environments, and off-axis placement options are broader than any of its competitors with both vertical and horizontal keystone correction. It cannot handle 3-D, but everything else in in range. Is it worth roughly ten percent more than most of its competitors? The answer depends on your needs, but in our book, it is a decision worth considering seriously.
