Overview
A polycarbonate lamp head holding several LED sources gives this Nitecore headlamp a choice of color temperatures. It rides on an ultra lightweight string headband and runs on an included lithium-ion battery charged by cable.
Weight saving drives the design, with a string band in place of a wide strap and a compact matte head. Runtime appears without a brightness mode, and the battery is a nonstandard cell, so a spare is not a corner-shop purchase.
Who it's for
Suited to trail runners, ultralight hikers and climbers who carry a small light for dawn starts. Anyone expecting a wide comfort strap or field-replaceable batteries should look at another headlamp.
Pros and cons
- Multiple color temperatures
- Ultra lightweight string headband
- Rechargeable battery and cable included
- Waterproof per listing
- Nonstandard battery, hard to replace
- Runtime mode not listed
- Headlamp weight absent despite lightweight claim
Performance notes
Brightness and runtime pull against each other, so the listed runtime applies to one unstated setting and other modes will differ. Color temperature choice changes how terrain contrast reads, with warmer light often easier in fog or rain. A string headband spreads load less than a wide strap, which affects comfort rather than light output.
