Cheap and Bright
How low can classroom projectors go? With the introduction of Epson’s PowerLite S11 and X12, it appears to be $450. Both use three LCD panels, produce XGA images onscreen and have lamps that are rated for 5,000 hours of use. While the S11 produces 2,600 lumens of light, has traditional VGA connections and costs $450, the X12 pumps out 2,800 lumens, adds an HDMI input jack and costs an extra $100.
