Overview
Trails and campsites after dark are where the Coast headlamp does its work, with a built-in lithium battery charged by USB. One button controls the white beam, and a twist of the bezel moves it from flood to spot.
Quick beam changes and a red mode that preserves night vision suit hikers, runners and anyone working in low light. The limitation is the battery: it cannot be replaced by the user, and the listing gives no charge time or low-battery behavior.
Who it's for
An outdoor user or tradesperson who moves between wide close-up light and a longer reach, and prefers a rechargeable unit. Travelers who want to use disposable cells in an emergency should choose a different lamp.
Pros and cons
- Focusing flood to spot beam
- Separate red light
- Rechargeable by USB
- Reflective safety strap
- Battery not replaceable
- Charge time absent
- Green mode not described
- Dimension fields conflict
Performance notes
The white beam is adjusted by twisting the bezel, which narrows the light into a reaching spot or widens it into a flood. Brightness and battery condition set the runtime, and the listing states output and runtime to ANSI/FL1 standards. A fixed red LED preserves night vision when reading maps or moving around camp.
