ISTE 2013: Short-Throw, Long Lamp Life
The latest in short throw projectors are models from BenQ that have lamps that can last as long as 10,000 hours, or the equivalent of six or seven years of typical school use. In fact, the lamps for the MX819ST and MW820ST will likely outlive the projectors. Both projectors use 6-color wheel DLP imaging chips to deliver XGA and wide-screen WXGA resolutions with 3,000 lumens of brightness. The projectors can automatically adjust brightness based on what is being projected to allow the lamp to last longer and reduce power needs.
