Ledlenser HF4R Core Rechargeable LED Head Torch

The Ledlenser HF4R Core Rechargeable LED Head Torch is the new addition to the Ledlenser Core series featuring a 10 second boost output which offers a maximum of 500 lumens, while the highest constant output is 300 lumens.

The HF4R Core is lightweight and compact, perfect for everyday use with a comfortable and adjustable slim headband and the white and red outputs are handy for various activities.

The light is a spot and flood beam combined which is operated with the power button on the top of the head torch by pressing it once to turn the light on, with each press after cycling through low mid, high and then off. Press the button within five seconds to cycle through the outputs or the next press will turn the torch off. The boost output can be activated by double pressing the button and will illuminate for 10 seconds before returning to the previous setting.

Press and hold the button for two seconds while the torch is off to switch between the white and red outputs. When in the red output press the button to turn the torch on or off.  

It is powered by a built-in lithium-ion battery pack, with up to 2.5 hours run-time in the highest constant output. The battery pack sits on the back of the headband, which helps to evenly distribute weight. The battery is charged via the magnetic charging point located on the bottom of the battery pack by connecting the magnetic end of the included cable to the charging point, and the standard USB into a suitable USB port or adaptor. The four LED battery indicators will gradually increase until all four are solid green to show charging is complete after approximately 2 hours for a full charge.

The LED indicators will also light up when the torch is turned on to show the remaining battery power, with four indicating 100%, three indicating 75%, two indicating 50%, one indicating 25% and one flashing indicating below 25%. The indicator flashes when charging is in progress and turns solid when charging is complete. The torch will flash twice to indicate low battery.

The swivel mechanism of the head lamp provides adjustment of the beam position within a 45° angle so that it can be exactly where you need it and features a colour rendering index of 70 and a colour temperature of 5200 to 6200 K.

There is also a lock out mode to prevent accidental activation when not in use, which can be turned on or off by holding the button for 5 seconds until the light blinks twice.

The HF4R Core has a ingress protection thanks to the flex sealing technology, offering a rating of IPX8 and an increased robustness with a drop resistance of 2 metres.
