That means 4 hours a day can last you 20 years. * LED Light not only delivers a wider color range and deeper color saturation than traditional lamps - its ultra-fast, pulsing LED-light eliminates motion blur and color break-up. * No need to crowd around the small screen. See your content on the big screen using Intel WiDi. * Easily view office and PDF files by connecting a thumb drive to the projector. No need to convert the original file.
