Flagship 10,000-lumen headlamp with RGB, Bluetooth and hard case
Sitting at the top of the 2026 range, the H21R delivers 10,000 lumens of Boost output through Multi-Lens Technology — the highest in the H series. Two switches (side multifunctional and top) give quick access to different beam functions without cycling through modes, backed by Adaptive Light Beam automation and Digital Advanced Focus System manual control.
Built-in red, green and blue front lights cover specialist use, an optional red rear light adds visibility to others, and the reflective headband makes the wearer visible from 360°. Bluetooth pairing via the Ledlenser Connect App enables remote personalisation. A four-cell 18650 battery pack delivers 50.9 Wh for the highest capacity in the range, and a hard-shell carry case ships in the box for safe transport.
