    • Constant Mode – Most headlamps auto-regulate lumens to conserve battery life, dimming over time as your eye adjusts to darkness. While this can be efficient in a lot of cases, it shouldn’t be the only mode available for dealing with technical terrain or pitch darkness. Constant Mode puts users in control.

Our Thoughts on the Updated BioLite Headlamps

We has a chance to test out the Headlamp 325 and the Headlamp 425 and were very impressed with the fit and feel of the 3D SlimFit Construction, there was no bounce when we took them out running and the bands helped wick away sweat keeping the forehead cool and dry. The articulating front bezel, bright illumination and plenty of the light modes proved exceptionally useful while hiking and around the campsite. We also have to applaud BioLite for stepping outside of the industry standard micro USB charging port and deciding to build the Headlamp 425 with a USB-C charging port, allowing it to be charging cord compatible with the rest of our tech. Both of the headlamps get high praise from us for fit and functionality, but if I was to recommend one of the three, it would definitely be the Headlamp 425, as it can cover almost all activities, is priced right and has that convenient USB-C charging port.
