The new Nite Lite 6-volt LED headlamp brings a new standard to brightness and burn time. When designing a new LED headlamp, we ensure it's compatible with all Nite Lite 6-volt battery packs. Our new headlamp provides at least 2 hours of continuous burn time with any of our 6-volt battery packs. It features a high and low setting while producing a super tight spot. It's an amazing improvement over the incandescent style headlamps. No more bulbs to buy and no more beam adjustments will be necessary to achieve a tight spot. Rugged, yet lightweight design, maintains the essence of what a coon hunter's headlamp should be. Nite Lite 6 Volt LED Headlamp
