5 Tips for Choosing a Flashlight for Hiking and Trekking
① Weight: Under 200g is the Standard for Hiking
In hiking, the total weight of your gear directly impacts your physical endurance. Aim for a flashlight weighing under 200g. Always check the weight including the battery. If you're combining it with a headlamp, a compact model around 100g is ideal as a secondary light.
② Waterproof Rating: IPX5 or Higher is Essential, IPX6 Recommended
Mountain weather can change suddenly. There's always a risk of getting wet from sudden rain, fog, or river crossings. IPX5 (jet-proof) or higher is the minimum requirement, and for serious mountaineering, IPX6 (powerful jet-proof) or higher is recommended. For details on waterproof ratings, please refer to our Flashlight IPX Waterproof Rating Guide.
③ Continuous Lighting Time: 8 Hours or More for Peace of Mind
Even on day hikes, your descent can be delayed. Choosing a model that offers 8 hours or more of continuous lighting will help you handle unexpected situations. Models with multiple brightness modes can extend lighting time in power-saving mode.
④ Brightness Modes: Balancing High Brightness and Power Saving
In hiking, adjusting brightness according to the situation is crucial. You can efficiently use battery power by switching between high brightness (1,000lm or more) for dark trails and low brightness (10–50lm) for inside a tent or reading maps.
⑤ Impact Resistance: Durability Against Drops and Shocks
In hiking, flashlights often experience impacts, such as falling on rocky terrain or being compressed by luggage. Choosing a model with 1m or more of drop resistance provides peace of mind.
Recommended Flashlight Usage for Different Hiking Scenarios

Tips for Carrying and Managing Your Hiking Flashlight
Prepare Spare Batteries / Charging
Since you can't charge in the mountains, carry a power bank (10,000mAh or more) or bring fully charged spare batteries. If your model supports USB charging, you can even charge it in the mountains with a power bank.
Storage in a Waterproof Case
Storing your flashlight in a waterproof pouch or bag within your backpack provides peace of mind against sudden heavy rain. This is essential, especially if you anticipate river hiking or crossings.
Headlamp vs. Flashlight Usage
Ideally, hikers should carry both a headlamp (hands-free) and a handheld flashlight (for long-distance or emergencies). The handheld flashlight is essential as a backup in case your headlamp malfunctions.
