The TANK007 UVC31 UV 365nm 5W USB Rechargeable Torch is a versatile and high-performance UV flashlight, designed for a wide range of professional and investigative applications. Featuring advanced Japanese Nichia UV LEDs, this torch provides pure ultraviolet light with remarkable intensity and durability. This review explores the various features, technical specifications, and practical uses of the TANK007 UVC31, showcasing why it stands out in the market for UV flashlights.

The TANK007 UVC31 utilizes an original Nichia UV LED from Japan, known for its high quality and longevity. With a peak wavelength of 365nm, this flashlight emits pure ultraviolet light that is ideal for various detection and investigative tasks. The LED has an impressive lifespan of over 20,000 hours, ensuring that the flashlight will provide reliable performance over an extended period.

The UV intensity of the UVC31 is notable, with more than 72,000μW/cm² at a 15cm distance and over 30,000μW/cm² at a 38cm distance. This high intensity allows the flashlight to reveal details and substances that are otherwise invisible to the naked eye, making it an invaluable tool for professionals in various fields.

Powered by a single 18650 Li-ion battery, the TANK007 UVC31 offers a runtime of at least three hours on a full charge. This makes it suitable for extended use in the field without the need for frequent recharging. The flashlight features a USB Type-C charging port, supporting DC 5V direct charge. The Type-C interface allows for positive and negative insertion, effectively preventing incorrect insertion and ensuring a reliable charging process.

The charging system is designed with user convenience in mind. The flashlight includes a three-color indicator system: red light indicates charging, green light signifies full charge, and blue light shows that the flashlight is in regular operation. This clear and intuitive indicator system ensures that users are always aware of the flashlight's charging and operational status.

Constructed from aircraft-grade aluminum T6061, the TANK007 UVC31 is built to withstand harsh conditions and rough handling. The premium Type III hard-anodized anti-abrasive finish provides additional durability, ensuring the flashlight remains in excellent condition even after prolonged use. The specialized black lens filter is designed specifically for UV light, effectively filtering out visual light to reduce interference and enhance UV detection capabilities.

The flashlight is waterproof with an IPX-7 rating, allowing it to be used in wet conditions or even submerged in water up to 1 meter deep for short periods. Additionally, the UVC31 can withstand drops from heights of up to 1.5 meters, making it a reliable tool for rugged environments.

The TANK007 UVC31 is incredibly versatile and suitable for a wide range of applications:

Leak Detection: The flashlight can detect leaks in special gas pipes, oil pipes, air conditioners, and automotive circulation systems. Its high-intensity UV light makes it easy to spot fluorescence from leaking substances.

Industrial Inspection: It can detect fluorescence penetration and fluorescent powder in industrial equipment, providing a non-destructive method for inspecting machinery and systems.

Forensic Analysis: The UVC31 is essential for crime scene investigation, capable of revealing clues such as bloodstains, semen, fingerprints, and hair. UV light can make sexual fluids fluoresce and reveal discolored bruises and fingerprints, aiding forensic experts in their analyses.

Fire Investigation: It can identify chemical combustible materials at fire scenes. Under UV radiation, residues of such materials on walls, furniture, and the ground become visible, helping investigators determine the cause of the fire.

Gemology and Antiquities Verification: The flashlight can authenticate A, B, and C grade emeralds, ivory, bones, wolf teeth, ancient paintings, books, and porcelain, by highlighting their unique fluorescent properties under UV light.

Maintenance and Cleaning Verification: It can check the cleanliness of pharmaceutical equipment using riboflavin and identify oil stains and blots by stimulating a fluorescent reaction in grease and similar substances.

Currency and Document Authentication: The UVC31 is effective for identifying various anti-counterfeit measures in banknotes, invoices, ID cards, passports, and credit cards. It reveals hidden security features that are not visible under normal lighting.

Biological Research and Mineral Exploration: The flashlight is useful for inducing fluorescent reactions in special materials and identifying unique minerals, making it a valuable tool for researchers and treasure hunters alike.

Operating the TANK007 UVC31 is straightforward. The flashlight features an end click switch for easy on/off control. To switch modes, users simply press and hold the switch, allowing for quick transitions between different brightness levels and functions.

The flashlight's compact size (15.9 cm in length, 2.6 cm body diameter, and 4.0 cm head diameter) and lightweight design (194 grams excluding batteries) make it highly portable and convenient to use. Its ergonomic design ensures a comfortable grip, even during extended periods of use.
