Fenix builds some of the most reliable flashlights on the market, and their UV lineup is no exception. Whether you need one for scorpion spotting, leak detection, or scanning surfaces during a paranormal investigation, a Fenix UV flashlight gives you consistent ultraviolet output backed by solid build quality that cheaper alternatives just can’t match.
But Fenix offers several UV-capable models, and they’re not all built for the same job. Some prioritize raw UV power, others blend UV with visible light, and prices range from budget-friendly to premium. Picking the right one comes down to knowing what you actually need it for, which is exactly why we put this guide together. At Haunt Gears, we test and review gear that holds up during real investigations, and UV flashlights are a staple in any serious kit.
Below, you’ll find seven current Fenix UV flashlight models broken down by specs, features, and pricing so you can compare them side by side. Each entry covers what makes that model worth considering and who it’s best suited for, so you can skip straight to the one that fits your use case.
1. Haunt Gears top pick: Fenix TK35R UV
The Fenix TK35R UV earns the top spot because it delivers high UV output in a build designed for demanding real-world use. If you’re running overnight investigations or scanning large surfaces for extended periods, this flashlight handles the workload without cutting corners on durability or runtime.
What you get
Fenix designed the TK35R UV as a dual-LED tactical flashlight that combines a high-power white LED with a dedicated UV emitter, so you’re not carrying two separate tools into the field. The body uses aircraft-grade aluminum alloy with a hard-anodized finish, making it resistant to impact and corrosion during rough use. It charges via USB-C, which means one cable handles both your phone and your flashlight when you’re packing gear for a trip. A 21700 Li-ion battery comes included in the box, so you’re ready to run it straight out of the packaging.
UV output and best uses
The UV emitter runs at 365nm, which is the wavelength that serious detection work calls for. At 365nm, you get minimal visible purple glow and strong fluorescence response, which matters when you’re trying to pick up faint traces on surfaces during an investigation. This makes the TK35R a standout fenix uv flashlight for identifying bodily fluids, scorpions, counterfeit currency, and residues that white light misses entirely. Paranormal investigators benefit specifically from the 365nm output because it reveals stains and markings on walls, floors, and furniture that can support evidence documentation.
A 365nm UV wavelength produces far stronger fluorescence reactions than cheaper 395nm alternatives, making it the preferred choice for investigators who need reliable, repeatable results in the field.

3. Fenix TK25 UV tactical flashlight
The TK25 UV occupies a practical middle ground in the Fenix lineup. It runs dual LED emitters in a compact tactical body, giving you both a powerful white beam and a UV channel without the size and weight of a full-size duty light.
What you get
Fenix built the TK25 UV with a side-mounted UV emitter alongside the primary white LED, so switching between visible and UV light takes a single button press rather than swapping tools. The body is aircraft-grade aluminum with a type-III hard-anodized finish, and it’s sized to fit comfortably in a jacket pocket or tactical pouch. It runs on a single 18650 battery, which is easy to source and replace during back-to-back investigation nights.
UV output and best uses
The UV emitter on the TK25 runs at 365nm, matching the wavelength standard you find across the serious end of the Fenix UV lineup. That output makes it a capable fenix uv flashlight for surface scanning, stain detection, and fluorescent trace identification during field work. The dual-output design is especially useful when you need to quickly alternate between white light for navigation and UV for close-up evidence checks without interrupting your workflow.
Running a 365nm emitter alongside a high-output white LED in one body eliminates the need to carry a separate UV tool on active investigations.

7. Fenix LD32 UVC flashlight
The LD32 UVC stands apart from every other model on this list because it does not use a 365nm wavelength. Instead, it outputs UVC light at 275nm, which shifts its purpose entirely toward [germicidal applications](https://hauntgears.com/product-tag/uv-flashlight/) rather than fluorescence detection.
What you get
Fenix built the LD32 UVC with a compact aluminum body that runs on two CR123A batteries, keeping the form factor manageable without sacrificing build quality. The dedicated UVC emitter sits behind a protective lens designed to direct output onto surfaces for sanitization, and the single-mode operation keeps the controls simple. There is no white LED on this model, so it functions as a purpose-built sterilization tool rather than a dual-output light.
UV output and best uses
The 275nm UVC output makes this fenix uv flashlight fundamentally different from the detection-focused models earlier in this list. UVC at that wavelength disrupts microbial DNA and is used for sanitizing surfaces, equipment, and personal gear rather than revealing fluorescent traces. Investigators who prioritize equipment hygiene between field sessions will find this useful, particularly when sharing gear across a team. It is not suited for scorpion spotting, stain detection, or document verification.
UVC at 275nm carries enough energy to cause skin and eye damage with direct exposure, so you should always follow the safety precautions outlined in the product manual before use.
