Bright Light in the Classroom
If 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.
