The Ledlenser H21R is a high-output rechargeable head torch built for extreme outdoor sports, maritime use and demanding professional applications including railway maintenance and search and rescue. Delivering powerful illumination with the flexibility to switch between a focused long-range spot and a homogeneous close-range flood, it adapts to everything from fast-moving mountain bike descents in darkness to detailed inspection of track machinery in confined tunnels.
Adaptive Light Beam automatically adjusts brightness and focus for seamless hands-free operation. For manual control, the Digital Advanced Focus System shifts between flood and spot via two control buttons. RGB colour modes — red for night vision, green for wildlife observation and blue for liquid detection — extend operational versatility further, while a reflective headband and optional rear red light improve visibility to others.
The rear-mounted battery pack provides balanced weight distribution for extended wear, and the battery supports pass-through charging — remaining operational whilst connected to power during long shifts. Helmet mounting accessories are included, the Ledlenser Connect App enables remote control and custom light profiles, and a hard-shell carry case is supplied for storage and transport.
Constructed with recycled materials and backed by a seven-year warranty with online registration.
