DARKBEAM UV flashlight 365 nm

The two-wavelength setup gives you a less visibly bright 365 nm light for more demanding detection and a brighter-looking 395 nm blacklight for general searching. This rechargeable two-pack is aimed at household checks and small tasks, from looking for pet urine marks to inspecting fluorescent materials or curing UV resin. Each light has a zoomable beam, a clip and an IPX4 water-resistance rating. The trade-off is that the 365 nm beam can look dim to your eyes, so visible brightness alone is not a useful way to judge it.

Technical details

The pack includes one 365 nm flashlight and one 395 nm flashlight. Both are listed as 10 W, with one lighting mode and a zoomable lens that adjusts the beam from wider to narrower. The rechargeable battery is included, the listing states up to 8 hours of runtime and a 3-hour full charge using 5V 2A power. A USB charging cable is included, and the indicator shows red for low battery or charging and green when full.

The housings are aluminium alloy, and the lights are described as IPX4 water resistant. That rating is for drops and humid conditions, not a claim that they can be submerged. A clip makes them easier to carry in a pocket, bag or toolbox.

Getting the most from it

There is no specific compatible device or accessory listed, so the useful distinction is between the two wavelengths. The 365 nm light is intended for fluorescent reactions and security-code detection, with less visible light spill, the 395 nm option appears brighter and suits broader blacklight searches. Both can be used in natural light, though the listing says they perform better in the dark.

For example, you could darken a room, widen the beam to scan a section of floor for possible pet stains, then narrow it to inspect a smaller spot. The lights are also listed for checking uranium glass, jewellery, currency, stamps, ores, glue or cracks, and for UV resin curing. May interest you if you want separate lights for focused detection and more general blacklight use. A simpler single-wavelength torch may suit you better if you only need one type of UV inspection.

Usage tips

Start with the beam wide when scanning a larger area, then narrow it to look more closely at a suspected mark, the adjustable lens is meant for changing the illuminated area. For pet-stain searches, dim conditions should make fluorescent traces easier to spot than a brightly lit room. The 365 nm beam may not look as bright as the 395 nm one, so choose by the task rather than by which appears stronger.

There is only one lighting mode, operated by clicking on and off. That keeps operation straightforward, but there is no listed brightness adjustment or choice of extra modes. Based on the listed details, charging takes about 3 hours with 5V 2A power, the stated runtime is up to 8 hours, rather than a guarantee for every use.

Buying questions

Are both wavelengths included? Yes. The pack is described as containing a 365 nm light and a 395 nm light.

Can it help find pet urine? Pet urine detection is one of the listed uses. The product information does not specify results for every surface or stain, so treat fluorescence as a clue to inspect rather than a confirmed identification.

Can I use it around moisture? It is rated IPX4 and described as suitable for drops or humid conditions. The listing does not say it is safe to submerge.

Before you buy it

This set makes sense if you want two UV wavelengths, a rechargeable format and a beam you can adjust for room-scale scanning or closer inspection. It is also practical to keep a light within reach, since the included clip can attach it to a pocket or bag. May not be the best option if you need multiple modes, a specified detection range or a stronger visible beam from the 365 nm light, those details are not provided. Choose it for the flexibility of the two wavelengths, not as a substitute for a dedicated tool when your task requires more precise performance information.
