Princeton Tech Refuel is best known for its simplicity and being extremely user-friendly. With only one mode, a dimmable white flood beam, now operating at 300 lumens, Refuel is easily and intuitively activated, deactivated, and dimmed with a single large, easy-to-find button. With its asymmetrical single arm bracket, the headlamp is effortlessly positioned to direct light wherever needed. Refuel also has an extremely easy-open battery door thanks to its larger lip, making battery swaps more painless then ever. The light is also very compact as the smallest of our 3 AAA headlamps at 78 grams, perfect for situations with limited pack space.
