BioLite HeadLamp 425 Rechargeable LED Head Torch

The BioLite HeadLamp 425 is a compact, rechargeable head torch that weighs in at only 78 grams. It is available in three different colours and offers both spot, flood and strobe outputs.

The 3D Slimfit construction prevents bounce as the housing is integrated directly into the headband for a flush front that stays put, while the moisture wicking smart fabric of the headband keeps you comfortable and dry. Additionally the headband features a rear red light to keep you seen and safe.

The spot LED provides a maximum output of 300 lumens white light and a beam range of up to 85 metres, while the white flood LED provides a maximum output of 125 lumens. Both white and spot can be used together to provide a combined maximum output of 425 lumens. There is also a red flood ouput. Both white and red outputs are dimmable to get the ideal brightness, and the head torch has a hinged bracket, allowing the light to be tilted for the best angle.

A single button on the top controls all the outputs, and will cycle through the outputs with each press within 0.5 seconds of each other in the order of red flood, white spot, white flood, white spot + flood, white strobe and off. If in any mode for longer that half a second the next press will instead turn the light off. To dim the brightness between high and low in either the white spot, white flood or white spot + flood setting, simply hold down the button and release at your desired output. The brightness will decreases or increase, and flash to let you know once it reaches the maximum at either end.

The HeadLamp 425 has mode memory and will remember the last used setting (for 12 hours) when you next turn it back on, which is useful if you are carrying out a task in a particular mode that requires you to keep turning the light on and off.

The integrated 1000 mAh lithium-ion battery sits in a battery pack on the back of the head, and can be charged by lifting the dust cover on the underneath to reveal the micro USB-C port. Then simply plug the included USB-C cable into the charging port and the other end into a suitable USB power source. The four charging indicators next to the charging port will flash and become solid in turn, until eventually all four lights are solid to indicate a full charge. Remove the cable and ensure the dust cover is properly replace to maintain the IPX4 water resistance rating. The four indicators will also display the battery power for three seconds when the light is first turn on, and again when it is turned off.

A lockout function prevents accidental activation in transit and the HeadLamp 425 is put into lockout mode by holding the button down for 8 seconds while the light is off until the red light blinks twice. To exit lockout mode repeat the process again, and the red light will blink once. This will also need to be done when you first take it out of the packaging as it is stored in lockout mode to preserve the battery.

Thanks to the adjustable clips on the headband, the torch can fit both children and adults, and the band is adjusted by pulling on both clips at the same time to tighten or pushing them closer to loosen the headband.
