Leffis v001 40X Jeweler’s Loupe with LED/UV Light and Folding Metal Case
Product description
Built-in LED and UV lighting helps illuminate small details when room light is limited, while 40X magnification brings close-up features into view. The Leffis v001 folding jeweler’s loupe combines an optical glass lens with a metal construction in a pocket-size design for detailed inspection at home, in a workshop, or on the go.
Pull out the loupe when you need a closer look, then fold it closed to protect the lens between uses. At 3.1 ounces, it’s easy to carry for collecting, craft projects, and hands-on repair work.

The essentials
The 40X glass lens is suited to examining fine details on jewelry, coins, stamps, rocks, and other small objects. LED illumination helps when working in dim or uneven light, and the additional UV light supports inspection tasks involving paper currency, passports, paintings, and geology. These are useful features in one handheld loupe, rather than a basic magnifier that relies solely on the surrounding light.



Its folding metal design keeps the lens covered for carrying and storage. The loupe measures 2.25 inches long by 1.15 inches wide and runs on three LR1130 batteries, which are included. Need to inspect a tiny mark or surface detail away from a well-lit desk? The built-in lights make this a practical tool to keep with collecting or repair supplies.
Buyers often praise the lighting and optical clarity, and describe using the loupe for varied items, from jewelry to electronics. Feedback on its size and durability is mixed, so those impressions may differ from one owner to another.

Best use cases
For jewelry and coin collectors, the 40X view helps bring small features into focus during close inspection. Stamp and rock collectors can use it to examine fine surface details, while crafters and jewelry makers may find it useful for intricate work such as beading. The LED light is handy when a work area needs extra illumination, the UV light adds a separate option for the listed inspection tasks.



It can also serve as a portable close-up tool for electronics or computer repair. Compared with carrying a larger bench magnifier, this folding loupe prioritizes a compact format that can be kept with a kit and brought to the object being examined.
How to use it

Pull the loupe out of its folded position to use the magnifier, then fold it back into its cover when you’re finished. For detailed viewing, position the lens over the small area you want to inspect and use the illumination that suits the task. The included three LR1130 batteries power the light features. Keeping the cover closed between uses helps shield the glass lens while the loupe is stored or carried.
