How to Buy the Right Hiking Headlamp

When selecting a hiking headlight, consider lumens, which measure the light’s power; a range of 200 to 300 lumens is suitable for most regular hikes.

Balance brightness with battery consumption. Check the flashlight’s weight, as lighter options may have fewer features.

Decide between rechargeable or disposable battery types, keeping in mind the charging challenges in remote areas.

Look at its protection rating against humidity, water, and dust (measured in IPX ratings) and consider whether it includes red light for gentle and practical nighttime use.

In general, opt for reputable branded headlamps to ensure reliability and quality, as unknown brands may not live up to their specifications.
