He added: “These are the smallest, quietest, and most stable projectors we’ve ever had. They also don’t throw off a lot of heat, which is important when you’ve got 20 people in the room.”

New ‘green’ projectors do away with mercury lamps

While the University of North Carolina relies on Canon’s accurate images, other schools and colleges are using Casio’s new lineup of Green Slim Projectors, eco-friendly projectors that eliminate the need for mercury lamps that typically must be replaced after 2,000 hours of use. Mercury can cause environmental damage if not disposed of properly.

The Green Slim DLP projectors use a patented hybrid “solid state” light source, which combines laser and LED technology to achieve high brightness, instead of a mercury lamp.
