The WPD-100 wireless unit is a tiny 802.11n (150 Mbps) USB adapter that is plugged into the back of the projector, although drivers are also included for Windows as well, including a clever soft-AP function. Brightness is rated at 500 lumens (which ViewSonic rates as roughly equivalent to a 1200-luman traditional light source), more than sufficient in a slightly-darkened room. Users can expect very long life (the spec is 20,000 hours) from this lamp, although the fan noise can be a bit loud. As noted earlier, the light source is LED. Connectivity includes HDMI, with 1080p compatibility – although the native resolution is only 1280×800 (720p). The image is surprisingly bright and clear, and suitable for small-scale home-entertainment applications as well.
The PLED-W500 projector itself is tiny (but not quite as small as the so-called “pocket projectors”) and light (only 1.6 lbs.), so it’s perfect for road warriors.
