It produces 28 lumens from a 1/2 watt LED and runs on one AAA battery, which is included, making it a straightforward option for checking gear, finding items, or moving around camp after dark.

Pros
- Compact, pen-sized design stays unobtrusive and easy to carry on person.
- 28-lumen white LED provides clear illumination for close-range tasks.
- Includes pocket clip, key ring, and lanyard for multiple carry options.
- Aircraft aluminum body with O-ring seal and polycarbonate lens.
- AAA battery included, so it is ready to use out of the package.
- Lightweight 1.04-ounce build keeps added bulk to a minimum.
Considerations & Trade-offs
- Compact size makes it easy to keep on hand, but the 28-lumen output is suited to close-range tasks rather than broad-area illumination.
- Runtime is listed at 1.5 hours, so it is best treated as a short-duration utility light rather than a long-use primary flashlight.
- It uses one AAA alkaline battery, which is convenient and widely available, but it also means you’ll need to manage spare batteries for extended trips.
- The included pocket clip, key ring, and lanyard add carry options, though the light’s very small format may feel less substantial than larger handheld flashlights.
