Fenix HM23 Ultralight LED Headlamp

Perfect for Any Adventure

The Fenix HM23 is a super lightweight and comfortable headlamp designed for high activity people that need reliable lighting suitable for several situations. This headlamp is equipped with a neutral white LED that can put out as many as 240 lumens that can shine up to 53 meters away. This specific LED color is a popular color temperature for its clear color recognition in natural environments. Running off of just one AA battery, maximum run time is 100 hours - more than enough time to complete your next adventure without stopping to change the batteries. The 180° adjustable beam is made possible with the high-elastic silicone holder, providing you with more beam angle options for the task at hand.

Ultra Comfortable

Fenix has revolutionized headlamp comfort by constructing the lamp body from high-strength aluminum, making it weigh less than a standard egg when you take out the battery! The new reflective headband weaving design reduces headband weight, allows for better breathability, and nighttime visibility. Even the silicone side switch (comfortable to the touch), was made with comfort in mind. The all-in-one button design is user friendly as you never have to see the headlamp to activate it or get to a different lighting output. Let Fenix light your way next time you want to enjoy the great outdoors!
