XJ-H1750, the current top of the line choice for Casio's Pro models. Casio rates it at 4000 lumens, and we measured it at about 3700. Along with the convincingly bright image, the DLP-based projector offers 1024x768 resolution, excellent data image quality, and lots of extras, from WiFi support to reading files directly from a USB memory key. As with earlier Casio models, however, the light source remains its most interesting feature and a key attraction.
Casio uses red and blue LEDs for the projector's red and blue primary colors, plus a blue laser shining on a phosphor element to produce green. Replacing a traditional mercury-based lamp is an obvious environmental plus. It also helps keep total cost of ownership down, since the light source is meant to last the life of the projector. Even at the hefty $2199.99 price, not having to buy replacement lamps can make the XJ-H1750 more economical than a less expensive projector with a $200 or $300 lamp replacement cost every 2000 or 3000 hours.
Other noteworthy features include five Eco levels plus an automatic Eco mode, which adjusts brightness based on ambient light. The result is both intriguing and an attractive choice for a medium to large size conference room or classroom, particularly if you give extra points for being eco-friendly.
