Headlamps

The headlamp is one of the most useful pieces of equipment for runners and trail runners. It is also an essential hiking accessory. The headlamp has even become mandatory in many competitions such as the UTMB. It is essential not only from a safety perspective, providing sufficient night-time visibility and helping prevent serious falls, but also from a practical point of view, as it allows you to see while keeping your hands free. Are you looking for a headlamp for trail running, a headlamp for running, road running or hiking, preferably rechargeable? Follow our advice to find the model best suited to your activity.

How to choose a headlamp? 

A headlamp allows you to see during night runs or evenings at a bivouac. Some headlamps are even intelligent: they adapt the light intensity and beam angle according to the environment. Among the most recognized headlamp brands are Petzl, Silva and Ledlenser. To choose the right headlamp, take into account: 

  • The power source
  • The light output
  • The range of your headlamp
  • The beam width
  • Water resistance
  • The lighting modes

Rechargeable or battery-powered headlamp? 

Thanks to LED headlamps, you can benefit from very good battery life, ensuring optimal lighting even during long races.

The advantages of battery-powered headlamps 

Battery life can range from around ten hours to several hundred, depending on the model. By choosing a battery-powered trail running headlamp or running headlamp, you opt for an easy-to-use model. We recommend battery-powered headlamps for long expeditions or trips to remote areas. They are also more affordable.

The disadvantage of a battery-powered running headlamp is that the quality of the lighting often decreases as the batteries run down. However, some lamps are designed to provide a stable light output that only decreases slightly as the battery is used. This is known as a regulated-output headlamp. It provides more consistent lighting, but be careful, as the light can suddenly switch off when the batteries are depleted. Another important factor to consider is the "burn time". This indicates how many hours a headlamp can produce usable light at a distance of at least two metres.

The advantages of rechargeable headlamps 

This type of operation is more sustainable. In everyday use, mains recharging is also much more economical. However, the initial investment is higher. Rechargeable headlamps can show their limits on long treks unless you carry external batteries to recharge them.

Headlamp light output 

The light produced by your headlamp is expressed in lumens. Depending on the modes available on your running or trail running headlamp, you can access lower-power settings. 

Headlamps range from 15 lumens to 750 lumens or more. For a night run where it is not completely dark, 40 to 50 lumens should be sufficient. For deep trails in dense forests, you will need a model capable of producing at least 100 lumens for adequate visibility. It is up to you to decide whether you need a very powerful headlamp for fairly short runs or lower brightness for longer routes that are already partially lit.

Headlamp range and beam type

Beam range indicates how far the lamp can project light. It is practical and reassuring to see far ahead, but it is also important to have sufficient width for good peripheral vision. The beam can therefore be wider or narrower depending on your needs: 

  • Narrow beam (from 10° to 30°): a headlamp with a narrow beam is essential for anticipating obstacles and clearly seeing the terrain.
  • Wide beam: we recommend these headlamps when peripheral vision is a priority. This type of lighting is perfect for bivouacs.
  • Mixed beam: it combines long-distance visibility with lighting of your immediate surroundings. You can see where you are stepping while also spotting upcoming obstacles. We recommend a mixed-beam LED headlamp for mountaineering or trekking. Note that some rechargeable headlamps allow you to switch from one beam to another at the press of a button. 

What level of water resistance should your headlamp have? 

To determine the water-resistance level of your trail running or running headlamp, check its IP rating (Ingress Protection): 

  • IPX4: the running, trail running or hiking headlamp can withstand splashes of water from all directions and can resist rain.
  • IPX5: your device can withstand multidirectional water jets. It can be used in heavy rain.
  • IPX6: your headlamp can withstand powerful water jets, making it suitable even for passing under a waterfall.
  • IPX7: it can withstand immersion for up to 30 minutes at a depth of up to one metre.

Headlamp lighting modes 

Headlamps can feature several modes depending on the type of lighting and brightness you need. Most offer at least a high and low mode. Others may include additional modes. These include:

  • Flashing mode, which acts as an emergency signal. Some models even offer a choice of flash speeds (slow and fast).
  • Low-power mode, which provides a stable light source while minimizing battery use.
  • Medium mode, which is not available on all models because it is less commonly used. Low mode is often preferred to extend battery life.
  • High mode, meaning maximum brightness, which is a good option for situations where you need more light, especially on descents.
  • Boost mode, found only on certain models. This feature projects a very intense beam of light for a short period of time (a few seconds).

Choosing your headlamp according to your activity

Each outdoor sport has its own specific requirements. Our different headlamp models meet the demands of each activity.

Headlamp for running 

A rechargeable headlamp is very practical because your outings rarely reach the battery's maximum runtime. We recommend a power output of 150 to 200 lumens with a narrow beam that illuminates far ahead. If you run in a group, a headlamp with a red light helps limit glare for your training partners. These three models should meet your needs: 

  • The Silva Trail Runner Free 2 Ultra 550-lumen mixed-beam IPX5 running headlamp. This rechargeable lamp can also operate with batteries.
  • The Petzl Iko 350-lumen mixed-beam IPX4 running headlamp.
  • The Ledlenser NEO 5R 600-lumen rechargeable headlamp with a wide beam and a range of 5 to 100 metres, IPX4.

Trail running headlamp

For short distances, follow the same recommendations as for a running headlamp. For ultra-trail running, the requirements are higher. We recommend a headlamp with a minimum output of 500 lumens and a focused beam. A rechargeable lamp remains a very good option, provided you make sure it is fully charged at the start. For example, you can choose: 

  • The Petzl NAO RL 1,500-lumen mixed-beam IPX4 headlamp.
  • The Silva Speed 5XT 1,200-lumen mixed-beam IPX5 trail running headlamp.
  • The Silva Scout 3X mixed-beam IPX5 headlamp.

Hiking headlamp 

When hiking, your slower movements allow you to choose a headlamp with a wide or mixed beam. In terms of power, 100 to 150 lumens is sufficient on easy terrain. If you are moving over rugged terrain, we recommend headlamps with 150 to 300 lumens. We have selected two models for you: 

  • The Petzl Actik Core 600-lumen mixed-beam IPX4 headlamp.
  • The Petzl Tikka 350-lumen wide-beam IPX4 headlamp.

Other useful headlamp features

You will find many types of headlamps incorporating a wide range of innovations such as:

  • A headlamp with an app allowing precise brightness adjustment from a smartphone.
  • Lithium batteries, which are a good choice for cold-weather use and lose very little charge when not in use.
  • The option to choose between a rechargeable battery and a battery pack.
  • Infrared sensors, an additional mode that can provide more precise lighting to help identify potential obstacles.
  • A temperature-control system that improves cooling, enhancing both your comfort and the lifespan of your LED headlamp. 
  • A top strap running from the front to the back of the head to improve the fit of your running headlamp.
  • Automatic adjustment of the beam angle and light intensity according to detected environmental conditions. This is the case, for example, with the Petzl NAO, a connected headlamp that allows this mode to be configured via Bluetooth using a smartphone.
