The compact Ledlenser HF4 is the entry point to the 2026 HF head torch range: a spot beam for distance, a flood beam for close-up work and an additional red front light to protect night vision. It runs on the three AAA alkaline batteries in the box, or on Ledlenser's rechargeable HF battery pack (sold separately), so a flat cell never leaves you in the dark. Made with recycled materials, rated IP67 and backed by a 7-year warranty on registration. Smoky Blue finish.
