K12 product Focus: Projectors
Although traditional projectors remain popular, many school districts now opt for ultra short-throw, interactive devicesall-in-one solutions that replace the costs and technological support once needed for whiteboards, flat screen monitors and other display technologies.
Ultra short-throw projectors—which can be mounted above a blank surface or a whiteboard—provide bright, shadowless images and can be connected to any number of display sources, including laptops and tablets.
Like whiteboards, many models let users interact directly with the image being projected.Some of the newest products allow up to 10 users to work together on the same image.
More schools are now choosing laser projectors, which have instant on/off image capability and no warmup wait. Laser projectors offer all the image quality and brightness of traditional lamp-based devices while also lasting longer—up to 20,000 hours. The downside is the cost, both initially and if the light source ever needs to be replaced.
For districts that use traditional projectors, lamp life in that segment is increasing, with some units able to exceed 5,000 hours before needing a replacement. Network connectivity is also improving, allowing IT staff in a central location to monitor hours of usage, shut down projectors at the end of the day and determine when new lamps are needed.
