The Ledlenser HF4R Work is a slim rechargeable headlamp for trades and industry. Two light sources give balanced close and long-range light with up to 500 lumens in boost mode and up to 130 m of beam distance, and the neutral light has a high colour rendering index so wiring colours and fine detail are easier to see at close range. A red front light is also available. Protective elements on the front improve impact resistance, and the lamp is rated IP68 for continuous immersion in water and drop tested to 2 m. The built-in 1000 mAh battery charges via the Magnetic Charge System, has a battery status indicator and runs for up to 8 hours on mid and up to 35 hours on low. The lamp head tilts, and it can be worn on a hard hat with the rubberised headband or the included helmet mount and adapter. It weighs about 79 g and comes with a magnetic USB-C charging cable.
