Product Description
365nm 10W UV Torch for General Fluorescence & Leak-Dye Inspection
This handheld 10W 365nm UV-A torch without black filter is intended for general fluorescence checks and fluorescent leak-dye inspection where a compatible tracer is used.
Because this version has no black filter, visible-light spill can be higher than on black-filter inspection models. Use it in low-light conditions for stronger fluorescence contrast.

Questions buyers ask before ordering
Frequently Asked Questions
Open a question to see the answer.
This torch is intended for leak-dye inspection where the system contains a fluorescent tracer compatible with 365nm UV-A.
Not necessarily. The product is intended to reveal compatible fluorescent tracer dye; it does not make an unsupported claim that every leak is visible without a suitable tracer.
Applications can include automotive, HVAC, refrigeration or other systems that use a compatible fluorescent tracer, subject to the tracer and equipment manufacturer's instructions.
Reduced ambient light can improve fluorescence contrast and make small traces easier to see.
No. Wavelength compatibility, tracer chemistry, viewing distance, ambient light and contamination all affect visibility.
Confirm that the tracer dye is intended for 365nm inspection and follow the dye and equipment manufacturers' safety and service procedures.
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.
