Product Description
120W 365nm Black Filter UV Torch for Gemstone & Mineral Inspection
This high-power 120W 365nm UV-A torch with black filter is intended as a fluorescence-inspection aid for UV-reactive gemstones, minerals, rocks and crystals.
Not every material fluoresces, and UV response alone does not prove authenticity or composition. Use it alongside appropriate gemological or mineral-testing methods.

Questions buyers ask before ordering
Frequently Asked Questions
Open a question to see the answer.
This torch is intended as a 365nm UV-A fluorescence-inspection aid for UV-reactive gemstones, minerals, rocks and crystals.
No. Fluorescence varies by material, impurities, treatment and viewing conditions, so lack of fluorescence does not by itself identify or disqualify a specimen.
No. UV fluorescence can provide an inspection clue, but it does not replace professional gemological testing or laboratory identification.
Reduced ambient light makes weak fluorescence easier to see and compare against nearby non-reactive areas.
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 where fluorescence contrast matters, such as inspection, stain checking, leak dye or material fluorescence tasks.
Gemstone / mineral inspection
365nm black-filter products are chosen for higher-contrast fluorescence and inspection tasks.
Not for blacklight ambience or 405nm curing workflows.
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.
