Nitecore EZ AA-R5 Ultra-Compact Flashlight EZAA-R5 is an incredibly small flashlight that packs a lot of power into its tiny, aluminum alloy body. Barely longer than the AA battery that powers it, the Nitecore flashlight has an "infinite brightness" power functionality that can adjust the brightness of the beam from six (6) lumens to 160 lumens, allowing you to use the pocket light for a wide range of applications. The flashlight has a robust, twist-activated switch that's easy to use, and it features extensive knurling for a secure grip at all times. The Nite Core EZAAR5 Pocket 160 Lumen Flash Light makes use of a high-powered CREE XP-G R5 LED bulb with a long life span of about 50,000 hours, set in a computer-designed alloy reflector for an excellent beam profile. What's more, Nitecore has equipped the EZ AA-R5 with a flat tail cap that allows you to use the tiny flashlight as a candle light. Take high-powered illumination everywhere you go with the nearly-microscopic Nite-Core EZ AA R5 Twist-Activated LED Light.
