The Nitecore NU20 Classic weighs 1.34 ounces with the battery and headband included, which is roughly what a AAA headlamp weighs before you even add its batteries. It pushes 360 lumens out to about 119 yards on high, then steps down through three white levels, a soft diffused reading light and a red auxiliary LED that keeps your night vision intact in a tent. On low it runs up to 97 hours, and it recharges over USB-C in a little over an hour, so it shares a cable with your phone instead of eating AAAs. The polycarbonate body is IP66 rated and drop tested to one meter. Fit note: the battery is built in and not user swappable, so on trips longer than a few days you are carrying a power bank rather than spare cells.
Pros
- 1.34 oz total, light enough that it stops registering as pack weight
- USB-C charging means one cable for phone, headlamp and power bank
- Red auxiliary LED and a soft reading light preserve night vision inside a tent
- IP66 rated and 1 m impact resistant despite the featherweight build
Cons
- The battery is sealed in, so you cannot swap in a fresh cell mid-trip
- 360 lumens is modest if you want to run trails at speed rather than hike
- The headband is fiddly to adjust the first few times
Frequently asked questions
Can I replace the battery?
No. The NU20 Classic uses a built-in rechargeable cell that is not user replaceable, which is part of how it hits 1.34 ounces. For weekend trips the 97 hour low-mode runtime covers you easily. For longer stretches without power you charge it from the same USB-C power bank you are already carrying for your phone, which is usually lighter than packing spare AAAs anyway.
Is 360 lumens enough for night hiking?
For walking a trail at hiking pace, yes, and the 119 yard beam distance gives useful reach for spotting trail markers. If you are running technical singletrack at night or need to light up a wide area around camp, this is underpowered and you want something in the 700 to 1,000 lumen range. Note also that maximum output is not sustained indefinitely, since small lights step down to manage heat and battery.
What is the red light actually for?
Red light does not constrict your pupils the way white light does, so it preserves dark adaptation. Practically, that means you can find something in your tent or check a map at 3 a.m. without blinding yourself or your tentmates and without needing several minutes to see in the dark again afterward. It also draws far less power than the white LEDs.
How does it hold up in rain?
It is rated IP66, which covers heavy rain and dust ingress but is not a submersion rating. Hiking through a downpour is fine, dropping it in a creek is not something the rating promises to survive. The body is polycarbonate and rated for a one meter drop, so ordinary trail knocks are not a concern.
