Choosing a good headlamp is crucial for runners and trail runners, as well as being an indispensable accessory for hikers. Allowing you to remain illuminated during night runs, headlamps have become mandatory in many competitions, such as the UTMB, for safety reasons to ensure sufficient night vision and prevent the risk of serious falls, as well as for practical reasons, as they allow you to light your way while keeping your hands free. Some headlamps, like the Petzl Nao, are even smart and can adjust light intensity and beam angle based on the environment, which you can configure via Bluetooth with your smartphone. Here’s what to consider to choose the right headlamp for you.
The headlamp is one of the most useful accessories for any runner or trail runner training at night or early in the morning before sunrise. It’s also handy for hiking, especially on multi-day treks. In fact, a headlamp is even mandatory in many long-distance competitions such as ultra-trails.
It is an essential tool not only for safety—providing enough visibility at night to avoid serious falls and to ensure you are seen—but also for practicality, since it lights your way while keeping your hands free.

A headlamp provides lighting for night runs or evenings spent camping outdoors. Some models are even smart: they automatically adjust brightness and beam angle depending on your surroundings. To choose the right headlamp, consider the following:

To determine the waterproof rating of your trail running or hiking headlamp, check its IP rating (Ingress Protection):
Thanks to LED bulbs, headlamps now have excellent battery life, ensuring optimal lighting even for long races, generally lasting 8 to 10 hours. However, the downside is that the quality of the lighting tends to decrease as the batteries wear out. Some lamps are designed to provide stable light that only slightly diminishes as the battery drains, known as lamps with regulated light output. These offer more consistent lighting, but be aware that the light will suddenly stop when the batteries run out. Another important factor is the "burn time," which indicates how many hours a headlamp can produce usable light at least two meters away.
The light provided by your headlamp includes two aspects: the intensity of the emitted light and the type of visibility provided by the available light. Light intensity is indicated in "lumens," the unit of measure for brightness. Lamps range from 15 to 750 lumens or more. For night running in not completely dark conditions, 40 to 50 lumens should suffice. For deep trails in dense forests, you'll need a lamp that can produce at least 100 lumens for adequate visibility. Decide whether you need a very powerful headlamp for short races or less brightness for longer journeys on partially lit paths.
Headlamps may include several modes depending on the type of lighting and brightness you need. Most offer at least a high and low mode, with additional modes including:
The beam distance, measured in meters, indicates how far the lamp can project light. It's useful and reassuring to see far ahead, but it's also important to have sufficient width for good peripheral vision. The type of beam can be more or less broad depending on your needs. Some headlamps, like the Petzl Nao, feature technologies that adapt the beam angle and light intensity based on detected environmental elements and can be configured in Bluetooth via a smartphone.
There are many types of lamps with diverse and varied innovations, such as:
