The Ledlenser MH4 is a rechargeable outdoor head torch from the Classic MH Series — delivering 400 lumens with a 180-metre beam, dual power source capability, a red front light for night vision preservation and the same detachable lamp head mounting system shared across the MH range. The 750mAh Li-ion battery charges via the included Magnetic Charge System USB-A cable, and AA alkaline or NiMH batteries can be used as a direct alternative when recharging is not possible.
The MH4 is an older generation product first released in 2018 — predating the 2026 H-Series and HF-Series, which offer significantly more output, more advanced features and longer runtimes. The MH4 remains a practical everyday outdoor head torch for hunters, anglers and outdoor enthusiasts who want rechargeable convenience, dual power backup and the clip mounting system in a compact 94g format without the additional features and cost of the current generation.
