4-Core 365nm UV Blacklight Flashlight – High-Power Rechargeable Torch

Unlock a whole new level of detection with this professional-grade 365nm UV blacklight flashlight. Powered by a quad-core 40W LED array and fitted with a premium black filter optical lens, this torch delivers pure, intense ultraviolet light that reveals what the naked eye simply cannot see. Whether you're a pet owner, rock hunter, hobbyist, or simply want to keep your home spotless, this is the UV flashlight you've been looking for.

Why 365nm — Not 395nm?

The 365nm wavelength is widely regarded as the gold standard for UV detection. Unlike 395nm lights, a true 365nm flashlight produces a far darker visible purple output, meaning fluorescent targets — stains, minerals, scorpions, and more — pop with dramatically higher contrast. Less visual "bleed" equals clearer results every single time.

Key Features

  • Quad-Core 40W LED: Four high-output 365nm UV LED chips deliver up to 800 lumens of ultraviolet energy for deep, wide-area coverage.
  • Premium Black Filter Lens: Hard toughened optical black glass filters out stray visible light, producing a purer, more powerful UV beam — the same technology used by professionals.
  • Reveal Hidden Stains: Instantly locate dry pet urine, food residue, bed bugs, and other invisible stains on carpets, upholstery, mattresses, bathroom tiles, and kitchen walls.
  • Rock Hunter's Best Friend: Makes fluorescent minerals and yooperlite rocks glow brilliantly with vivid orange under 365nm UV — 395nm lights simply cannot match this performance.
  • Multi-Purpose Detection: Authenticate banknotes, driver's licences, passports, and official ID cards; spot scorpions in dark environments; identify invisible ink markings; cure UV resin; and detect garden pests such as tomato hornworms.
  • Type-C USB Rechargeable: Includes a 5000mAh 21700 battery and charger with USB cable — ready to use straight out of the box, no extra purchases needed.
  • IPX6 Waterproof & Shock-Resistant: Rugged aluminum alloy body withstands daily use, rain, and accidental drops. Rear-button switch for effortless one-handed operation.
  • High / Low Switch Mode: Choose between full-power and lower-intensity modes to suit your task and conserve battery life.
  • Compact & Portable: Weighing just 153g with a pocket-friendly profile, this torch goes wherever you do — outdoors, travel, hotels, job sites.

Frequently Asked Questions

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

A: A 365nm UV flashlight emits a wavelength much closer to the true ultraviolet spectrum, which results in far less visible purple "bleed" and dramatically higher contrast when illuminating fluorescent targets. Stains, minerals, scorpions, and security markings appear brighter and sharper under 365nm light compared to 395nm, which produces noticeably more visible purple glow and lower contrast — making 365nm the preferred choice for serious detection work.

Q: Does the flashlight come with a battery?

A: Yes! This 365nm UV flashlight comes complete with one 21700 5000mAh rechargeable battery, a dedicated battery charger, and a USB cable. It is ready to use straight out of the box with no additional purchases required.

Q: Can this UV flashlight be used outdoors?

A: Absolutely. The aluminum alloy body carries an IPX6 waterproof rating, making it resistant to rain and splashing water during outdoor use. It is also shock-resistant, making it well-suited for rock hunting, camping, and field work. For best UV detection results, use in low-light or dark environments, as UV light performs optimally when ambient light is minimized.

Q: What surfaces and materials can this flashlight detect stains on?

A: The 365nm UV blacklight is effective on a wide range of surfaces including carpets, rugs, upholstered furniture, mattresses, bathroom tiles, hardwood floors, and kitchen walls. It is particularly effective at revealing dry pet urine, food stains, and other organic residues that are invisible under regular white light.

Q: Is this flashlight safe to use?

A: This flashlight is certified to CCC, CE, FCC, and RoHS standards. As with all UV light sources, avoid pointing the beam directly at eyes or skin for extended periods. Use responsibly and keep out of reach of children.
