See the video here: Pico Genie Ultra Portable LED Projectors - Applications in Schools
In this video, Miss Kelly shows how portable projection allows you to create a large screen, interactive environment, even in the smallest of spaces without any need for expensive set-up, bulbs, filters or equipment. Simply connect to your computer, tablet, smartphone (including Apple and Android devices) and mirror your screen at up to 100" from a device that fits in the palm of your hand.
With an LED projector, you can expect the light-source to last for 20,000 - 30,000 hours, run cooler, lighter, smaller and more energy efficient than a traditional bulb projector.
