365nm UV LED Flashlight 15W Rechargeable Ultraviolet Blacklight

Unleash the power of true 365nm ultraviolet light with this high-output UV LED flashlight. Whether you're authenticating currency, checking for leaks, verifying documents, inspecting surfaces, or exploring fluorescent minerals, this compact yet powerful blacklight torch delivers a pure, filtered UV beam that makes fluorescent materials glow brilliantly. Made in Mainland China.

Why Choose This 365nm UV Flashlight?

Unlike cheaper 395nm UV lights that emit a visible purplish glow, this flashlight operates at the true 365nm wavelength — the sweet spot for maximum fluorescence detection with minimal visible light interference. The optical filter eliminates white light contamination so you get crisp, clear UV-only illumination.

Key Features

Frequently Asked Questions

Q: What is the difference between a 365nm and a 395nm UV flashlight?

A: A 365nm UV flashlight emits light at a "true" ultraviolet wavelength with minimal visible purple glow, producing much stronger fluorescence in UV-reactive materials and cleaner results. A 395nm UV light emits more visible purple/violet light that can mask the fluorescent glow you're trying to detect. For professional-grade leak detection, document verification, or mineral hunting, 365nm is the superior choice.

Q: Is the rechargeable battery included with this UV flashlight?

A: Yes! The rechargeable battery is included in the package. Simply charge it before first use and enjoy approximately 4–10 hours of runtime per charge, making this ultraviolet flashlight ideal for extended sessions whether indoors or outdoors.

Q: Can I use this 365nm UV flashlight outdoors or in wet conditions?

A: Absolutely. This UV LED flashlight carries an IPX5 waterproof rating, meaning it is protected against low-pressure water jets from any direction. It's well-suited for outdoor use, camping, field inspections, and light rain — just avoid submerging it in water.

Q: What materials will glow under this 365nm UV blacklight?

A: Many materials fluoresce under 365nm UV light, including certain minerals (calcite, fluorite, scorpite), banknote security features, UV-reactive inks, HVAC leak detection dyes, pet stains, passport markings, and various adhesives. The filtered UV output of this flashlight enhances the visibility of fluorescent reactions significantly compared to unfiltered UV lights.
