Selection note
395nm UV-A is intended here for visible blacklight and fluorescent-display effects. Actual fluorescence depends on the material, ambient light and installation distance. This product should not be treated as a 405nm curing light, a 365nm inspection torch or a UVC germicidal product.

Questions buyers ask before ordering
Frequently Asked Questions
Open a question to see the answer.
This bulb is intended for UV-reactive signage and display lighting using materials that respond to 395nm UV-A.
No. Only UV-reactive or fluorescent materials will produce a strong visible response.
Dark or low-light conditions usually give the strongest visible fluorescence; bright ambient light reduces the effect.
No. 395nm is commonly used for visible blacklight and decorative fluorescence, while many inspection tasks use 365nm for different contrast characteristics.
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.

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.
