The LEDLenser HF4R Headlamp takes the HF4 body and slots in a Polymer USB-C rechargeable battery, pushing Boost output up to 650 lumens and Power mode to 400. Multi-Lens Technology drives the beam — spot for long range, flood for close-up illumination — through a single dual-beam optical system.

Charging is direct to the battery via USB-C inside the compartment, taking 210 minutes to a full charge. Dual Power Source design means the HF4R also runs on 3 x AAA alkaline batteries as a fallback, and the additional red front light protects night vision when it matters.
