Putting the BioLite Range 400 to the test. A headlamp built for real adventure, not just backyard camping. It packs 400 lumens, throws light up to 90 meters, and charges fast with USB C. Eight minutes of charging gives you about an hour of light. It’s IP67 waterproof, dustproof, and weighs only 2.6 ounces. You get white and red modes, full dimming control, and a no bounce moisture wicking headband that actually stays put on the trail. Whether you’re running through the dark or setting up camp at midnight, the Range 400 delivers bright, reliable light that keeps up with you. #BioLite #GearTest #TrailRunning #Ultrarunning #HeadlampReview #ad
