Overview
Twisting the bezel changes the white beam from a wide flood to a long spot with a transition halo. A second button switches to a fixed red LED to preserve night vision. It comes with three AAA batteries and a reflective strap.
Two beams and a red mode cover close camp work, trail walking and night-sight needs in one front-loaded lamp. The power source is the limitation: alkaline cells, no rechargeable option, and one spec field that quotes a lower lumen figure.
Who it's for
Hikers, campers and runners who like swapping AAA cells and want a dependable twist-focus beam suit this lamp. Users who prefer to charge by cable should look at a rechargeable model.
Pros and cons
- Twist focus from flood to spot
- Red LED preserves night vision
- Reflective safety strap
- Alkaline only, not rechargeable
- Water resistant, not waterproof
- One field quotes a lower lumen figure
Performance notes
Twisting the bezel moves the lens to trade a wide flood for a narrow spot with more reach. The red LED is a fixed output meant to preserve night vision. The seller says the lamp is impact resistant and weather resistant.
