Overview
Not a disposable battery lamp, this is a rechargeable headlamp with four LEDs, a red light mode and multiple color temperature emitters. A head band and a charging cable are in the box.
Low weight, USB-C charging and adjustable modes with red light suit packs where every gram counts. The limits are the unclear runtime figures and a plastic body with no impact rating listed.
Who it's for
Backpackers, runners and campers watching pack weight suit this lamp. Anyone relying on long runtimes in the brightest mode, or a documented drop rating, should look elsewhere.
Pros and cons
- Red light mode
- Multiple color temperature LEDs
- Runtime figures ambiguous
- Plastic body only
- Impact rating not listed
- Battery type fixed to lithium polymer
Performance notes
Four LEDs with multiple color temperatures let the lamp trade neutral white for other tones, and the red mode helps preserve night vision. Brightness and beam throw are set by the mode in use, so runtime drops at maximum output. USB-C charging refills the lithium polymer cell.
