The Ledlenser HF4R Work Headlamp is a compact rechargeable work headlamp designed for professional trades, construction, maintenance and industrial environments where durability, comfort and accurate illumination are essential
Engineered for demanding workplaces, the Ledlenser HF4R Work combines a slim, lightweight design with rugged construction and practical work-focused features. Its neutral white light with a high CRI of 80 delivers accurate colour rendering, making it ideal for inspections, electrical work, maintenance and other detailed tasks where colour accuracy matters.
Delivering up to 500 lumens in Boost mode with a beam distance of up to 130 metres, the HF4R Work uses Fusion Beam Technology to provide a balanced combination of wide flood lighting for close work and a focused spot beam for greater distance. The focusable optics allow you to adapt the beam to suit different working environments.
A dedicated red front light helps preserve night vision and provides discreet illumination when required. The 45° stepless tilting lamp head allows precise beam positioning, while the simple controls make operation quick and intuitive, even when wearing gloves.
Powered by an integrated 1000 mAh Li-ion rechargeable battery, the HF4R Work offers up to 35 hours of runtime on Low Power mode and recharges quickly using Ledlenser’s convenient Magnetic Charge System. Practical features including Memory Function, Backup Mode, battery and charge indicators, low battery warning and a Transportation Lock make it a dependable lighting solution for daily professional use.
Built to withstand harsh conditions, the Ledlenser HF4R Work features IP68 dust-tight and waterproof protection, 2-metre drop resistance and protective front elements for increased durability.
