Bright Light in the Classroom

Acer K335_03If LED projectors haven’t been bright enough for your classrooms, Acer’s K335 should do the trick with 1,000 lumens of light. The projector weighs less than three pounds and uses a DynamicBlack Digital Light Processing imaging chip that puts 1,280 by 800 resolution images on-screen. In addition to an SD card slot that can hold teaching material, the K335 has ports for HDMI, VGA and audio. It works with an MHL-ready phone or tablet, but you’ll need to buy the adapter cable. The best part of the K335 is that its illumination engine can go for 30,000 hours without a bulb change and is essentially maintenance-free. It costs $699.
