Producing 900 LED Lumens in “Bright” mode and 500 Lumens in battery mode, the M5 can project up to a 70” screen size in moderately lit rooms and more than a 10-foot screen size in rooms with controlled lighting. Measuring just 6″ x 6″ x 1.8″ and weighing in at a 1.95 lbs, this projector is a true micro projector that fits easily in a briefcase, purse, or laptop bag. The AAXA M5 features an ultra-high efficiency 4th generation solid-state optical engine. At the heart of this engine is AAXA’s vibrant color light-emitting-diode technology mated to Texas Instruments DLP imager. The M5 features the highest in-class native resolution at WXGA (1280 x 800), otherwise known as “high definition,” and is the base resolution for Blu-Ray movies. The M5 is also capable of scaling resolutions up to 1080p. Seventy-minute onboard lithium ion battery. This battery is known as a “premium grade” battery that is designed to retain 85% of its charge over 1000 charge cycles. The M5 employs a solid-state LED light-source. Unlike conventional projector lamps, solid-state LEDs last 5-10x longer (up to 20,000 hours), create more vivid colors and are more durable than conventional projector lamps. With LED Projectors there is no longer the need to wait for long lamp warm-up and cool-down times. The M5 LED Micro Projector’s LED light source enables it to achieve full brightness within seconds. It turns off instantly. Brightness: 900 lm; Technology: DLP; Weight: 1.95 lbs; Audio Output: 2W (x1) Stereo Speaker; Stereo Speaker/Headphone Mini-Jack.
