Product Description
365nm 20W UV Torch with Black Filter for Pet Urine & Stain Detection
This handheld 20W 365nm UV-A torch with black filter is intended for stronger pet urine and stain fluorescence inspection in homes, hotels, rental properties and cleaning work.
Use in dark or low-light conditions. Fluorescence depends on stain age, surface material, cleaning chemicals and whether the residue responds under 365nm UV.

Questions buyers ask before ordering
Frequently Asked Questions
Open a question to see the answer.
This torch is intended for fluorescence checks of pet urine and stain residues on suitable carpets, mattresses, upholstery, floors and similar surfaces.
No. Visibility depends on the age and composition of the residue, the surface material, cleaning chemicals, ambient light and whether the material fluoresces under 365nm UV.
A dark or low-light room generally improves contrast and makes fluorescent residues easier to inspect.
No. UV fluorescence is a detection aid and does not by itself identify the source or composition of a stain.
No. This is a 365nm UV-A inspection light and no germicidal or sterilization claim is made.
Treat it as a location cue, compare it with surrounding clean areas and use an appropriate cleaning or verification method for the surface.
Avoid direct eye exposure, do not stare into the light, limit unnecessary skin exposure, keep the product away from children and use suitable protective practices for the application.
Selection confidence
Confirm this is the right UV product before you buy
Use this product for general UV-A fluorescence checks where black-filter contrast is not the main requirement.
Application-specific UV use.
365nm UV-A is used for fluorescence checks where a black filter is not mandatory.
Choose black-filter 365nm when visible-light suppression matters.
Verified product information
Specifications that matter for this application
UV buyers need wavelength, geometry, power source, runtime or curing/inspection conditions—not just headline wattage.

Buyer guide
How to choose and use this product correctly
Use the application, wavelength, distance and power source together. Do not select a UV product on wattage alone.
Start with the application
Pick UV by job: inspection, glow/decor, curing, exposure work or compact lighting. Wattage alone is not a reliable buying shortcut.
Confirm wavelength
365nm, 395nm and 405nm serve different tasks. The product title, specs and use-case copy must agree.
Check distance and coverage
For curing and inspection, working distance matters. For floodlights and decor, coverage and mounting distance matter.
Match the power source
Handheld torches suit mobile checks. Floodlights, bulbs and strips are better for fixed areas, rooms, displays and workbenches.
