For focussing a narrow beam on the trail ahead, or lighting up a campsite or hut, headlamps are a versatile hands-free light source.
Straps
Wide enough to support the weight of the headlamp and allow easy adjustment so it doesn’t bounce around or slide down while you’re on the move. A top strap is found on models with a heavier, rear-mounted battery pack. Straps should be soft, comfortable and washable. An adjustable mounting for the light is useful for tilting the beam down or up.
On/off
The torch should be simple to operate with either a button or twist-action to activate the light. Glove-friendly operation is essential for use in winter. Dimmer switches adjust the light level and may be found on lamps with rear-mounted battery packs.
Functions and mode
One on/off button that can be toggled through the various lighting modes is usual. A twistable face will adjust the light from spot to floodlight. A transport lock is useful to prevent the headlamp being inadvertently turned on in your pack. Many headlamps have a red light function to preserve night vision – useful for reading and stargazing.
Output and range
Measured in lumens, light output can be adjusted for the conditions from a low 10 or 25 lumens for reading, up to 600 lumens for finding your way on the trail. Output also dictates range. Low-output models are useful work lights around the campsite or hut, while high-output headlamps are better for night tramping or running.
User settings
Some models allow the user to customise the output of the various lighting modes. This is useful if you want to conserve battery power and find the factory settings too bright. You need to adjust the settings on a computer while the torch is connected.
Run-time
Battery life is related to output; the more powerful the torch, the more power-hungry it is. Run-times shown in this feature are for the lowest and highest light settings (where only one time is shown, this is for the headlamp’s lowest light setting).
Water resistance
Headlamps have an IPX rating indicating their water-resistance:
IPX-4 Can handle splashing water (10-litre/min) from any angle – that’s most rainy conditions.
IPX-6 Protected against splashed and pressurised water from any angle from a 12.5mm nozzle at 100-litre/ min.
IPX-7 Full immersion in one metre of water for up to 30min. The perfect headlamp in extreme conditions.
IPX-8 Full and continuous immersion, up to and within the manufacturer’s specifications.
