Led Lenser HF4 Headlamp

Ledlenser HF4 – lightweight 450-lumen battery-powered headlamp

The Ledlenser HF4 is a lightweight and versatile battery-powered headlamp designed for hiking, camping, DIY projects, workshop tasks and everyday use. With a maximum output of 450 lumens and a beam range of up to 110 metres, it provides reliable visibility for both close-range work and viewing objects farther ahead.

Its combination of a focused spot beam and wide floodlight evenly illuminates trails, work areas and the space around you. A dedicated red front light helps preserve night vision, making it useful for camping, map reading and moving around after dark without excessive glare.

Adjustable light for different activities

Several white-light output levels let you balance brightness and battery life according to the situation. A low setting supports extended use, while the short Boost mode provides maximum output when additional visibility is needed.

Comfortable and ready for outdoor use

Weighing only 102 grams including batteries, the HF4 remains comfortable during longer periods of use. The lamp head offers stepless tilt adjustment up to 55°, while the detachable and washable headband is made from recycled materials. Its IP67 rating provides a high level of protection against dust and water.
