The Nitecore EAX Hammer is the latest in the company's line of high-output AA flashlights. This is the light to get if you want a ton of lumens without having to use lithium or lithium ion batteries. 8 AA batteries power two CREE XM-L2 LEDs for a blinding 2000 lumens on max output. The EAX has the same interface as the very popular EA4, meaning that you have quick access to lots of outputs and flashing modes. On low, the EAX Hammer will run for an impressive 800 hours.
