2500-lumen triple-source headlamp with spot, flood, and red light — powered by 21700 with dual switch
The Wurkkos HD16 is a triple-source headlamp that covers all the bases: spot, flood, and red light — each independently controllable via a dual-switch design. Running on a 21700 battery, it delivers 2500 lumens combined output with an impressive 297-meter beam distance on the spot beam, giving you genuine reach when you need to see down the trail or across a worksite.
The three light sources serve distinct purposes: the spot beam handles distance and focused tasks, the flood beam provides wide area illumination for close-up work, and the 660nm red light preserves your night vision for astronomy, camping, or wildlife observation. The dual-switch system lets you toggle between sources quickly without cycling through modes you don't need — a thoughtful design choice for a headlamp.
At just 70g for the head unit and 94.3mm in length, the HD16 is remarkably lightweight for a 21700-powered headlamp. USB-C charging keeps it topped up, and the 21700 cell provides significantly more runtime than 18650-based competitors. The aluminum body is robust enough for outdoor abuse. At $35, it competes directly with the Sofirn HS21 but trades gesture control for a simpler dual-switch interface and slightly longer throw.
