Wireless Light Source Wireless Standard: IEEE 802.11a/b/g/n (2T2R) OS environment: Windows 8/7/Vista/XP/2000, MAC OS X Supports MobiShow and WiFi-Doc projection. Mercury-free LED (up to 20000 hours in Normal mode) NOTE: The LED life rating for any projector is a measure of brightness degradation only, and is not a specification for the time it takes a LED to fail and cease light output. LED life is defined as the time it takes for more than 50 percent of a LED sample population to have brightness decrease by approximately 50 percent of the rated lumens for the specified LED. The LED life rating is not guaranteed in any way. The actual operating life span of a projector LED will vary according to operating conditions and usage patterns. Usage of a projector in stressful conditions which may include dusty environments, under high temperatures, many hours per day, and abrupt powering-off will most likely result in a LED's shortened operating life span or possible LED failure.
