Built around Ledlenser's Multi-Lens Technology, the LEDLenser HF4 Headlamp delivers 450 lumens of Boost output through a dual-beam optical system — a focused spot for distance and a wide flood for close-up work, both in one lens.

Power flexibility is the standout: run the HF4 on the 3 x AAA alkaline batteries included, or upgrade to a Polymer USB-C rechargeable pack (sold separately) for direct USB-C charging inside the battery compartment. The additional red front light preserves night vision when moving between bright and dark areas, or when others nearby need theirs kept.

• Multi-Lens Technology — spot for long range, flood for close-up illumination in a single optical system
