Nitecore HA13 Trail-Ready Take on your favorite trails at night with Nitecore's HA13! This 350-lumen headlamp is easy to use, with enlarged buttons for quick access to brightness levels and modes. The included red light makes this the ideal headlamp for backpackers and hikers - you'll be able to discreetly review maps or find small items around the tent without disturbing your night vision. Add in SOS and red-flashing modes so you can signal in emergencies at a moment's notice, and you have a well-rounded lighting tool built for the outdoors! Improved Functionality Stay economical with your battery use thanks to lock-out and ultra-low modes! The lock-out function will protect your HA13 from accidentally activating during transit, while ultra-low mode gives you up to 160 hours of runtime. Dual-Fuel Capable When it comes to powering the HA13, your options couldn't be easier. Use three AAA batteries - the HA13 accepts Alkaline, Lithium, or NiMH, giving you ample, readily available options. Or cut down on costs with the HLB1300 li-ion battery pack, a USB-C rechargeable pack that will keep your HA13 powered for extended runtimes. Take your pick of power source and spend more time doing the activities you love!
