With the addition of the second-generation CREE XP-G2 R5 LED emitter, Nitecore updated the MT1A LED Flashlight so that it now provides a higher maximum output than previous models. The MT1A is a compact light that features three normal outputs from 5 to 55 lumens, with a 180-lumen turbo mode. An intelligent two-stage pushbutton switch allows you to program your desired output, including a disorientating strobe or SOS emergency signal. To activate the turbo mode, just tighten the head slightly. This gives you access to your preferred operating output, while allowing you to quickly change to turbo mode.
Built for daily use, the aluminum housing has a scratch and corrosion-resistant hard-anodized finish, is submersible to 6.6', and impact-resistant to 5'. At just over four inches long and weighing only a few ounces, the MT1A is powerful enough to use as a primary light, yet fits comfortably in a pocket. The light runs on disposable lithium or li-ion rechargeable batteries, and there is a built-in reverse polarity protection that prevents damage to the light if the batteries are put in incorrectly.
