21 LED UV Flashlight 395-400nm Violet Light Aluminium Alloy Torch for Counterfeit Money Detection, Medical Inspection, Ink Curing and Pet Urine Detection, Silver, 95mm
21 LED UV Flashlight 395-400nm Aluminium Alloy Torch for Detection Tasks

This 21 LED UV flashlight produces violet light in the 395-400 nm wavelength range, placing it in the ultraviolet spectrum used for a variety of inspection and detection applications. The torch is constructed from aluminium alloy and has a compact body measuring 95 mm in length with a 35 mm diameter. It weighs 105 g or 115 g depending on the selected model. A tail clickie switch controls on/off operation, and the flashlight is powered by three AAA batteries, which are not included. The 21 LED configuration is one of three available LED counts, alongside 12 LED and 9 LED versions. Colour options include silver, black, and black set. The source text notes that some cheap blue UV lights on the market may not achieve the same ultraviolet light capture effect, positioning this product as a genuine UV nm device.
Features and Construction

The flashlight is built around a 21 LED UV light source with a stated wavelength of 395-400 nm. Its aluminium alloy housing provides a solid enclosure for the LEDs and internal electronics. The tail clickie switch offers straightforward on/off control. The torch measures 95 mm in length and 35 mm in diameter, with a weight of 105 g or 115 g. It runs on three AAA batteries, which the buyer must supply separately. Available colours are silver, black, and black set, and the model range includes 12 LED and 9 LED alternatives.
Material and Build
The body is made from aluminium alloy, a material commonly used for flashlight housings because it can be machined into a rigid, lightweight form. The stated dimensions are 95 mm in length and 35 mm in diameter. The 21 LED array sits within this housing. The tail clickie switch is positioned at the rear for thumb operation. The product is available in silver, black, and black set finishes, with 12 LED and 9 LED models also offered. The source text states that production follows European and USA standards, with UV nm testing on the lighting chip.
Size and Practical Fit
At 95 mm long and 35 mm in diameter, the flashlight is compact enough to hold in one hand or carry in a pocket or bag. Its weight of 105 g or 115 g is comparable to many small torches. The three AAA batteries fit into the handle, and the tail clickie switch sits at the base. The 21 LED head projects violet light in the 395-400 nm range. This size and layout make it suitable for handheld inspection tasks where a portable UV source is needed.
Uses and Placement

The source text lists a wide range of applications for this UV flashlight, including medical devices, disinfection sterilisation, ink curing, metal crack and crack detection, photocatalyst and light detection, money detect detector devices, anti-fake detection, medical measurements, biometric safety examination, hydraulic leak detection, amber inspection, scorpion detection, ticket and passport and credit card and identity card checks, animal urine test, phosphor powder and phosphor medium detection, ore jewellery and jade recognition, and checks on paper towels, facial masks, cosmetics, children's toys, books, and clothes. These uses rely on the 395-400 nm violet light output.
Event or Professional Use
For professional or event-based tasks, the flashlight can be used in medical device inspection, disinfection sterilisation routines, ink curing, and metal crack detection. It may also assist with hydraulic leak detection, biometric safety examination, and medical measurements. The 21 LED UV output at 395-400 nm is intended for these specialised detection scenarios. The tail clickie switch allows quick on/off control during use. The aluminium alloy body and compact 95 mm length support handheld operation in professional settings.
Everyday Home Use
Around the home, this UV flashlight can be used for counterfeit money detection, passport, credit card, and identity card verification, and animal urine testing. It may also help with checking paper towels, facial masks, cosmetics, children's toys, books, and clothes. Amber inspection, scorpion detection, and phosphor powder or phosphor medium detection are additional listed uses. The 21 LED violet light at 395-400 nm provides the ultraviolet output needed for these everyday checks. The silver, black, and black set colour options allow matching to personal preference.
Benefits and Buying Value

The flashlight is powered by three AAA batteries, which are widely available and easy to replace. Its aluminium alloy construction and compact dimensions make it a practical handheld tool for a range of detection tasks. The 21 LED model is one of three LED count options, giving buyers a choice within the same product family. The source text describes production under European and USA standards with UV nm testing on the lighting chip, and notes that some cheap blue UV lights may not achieve the same ultraviolet light capture effect. The 395-400 nm wavelength is the key specification for UV-dependent applications.
Reuse and Low Maintenance
The flashlight is designed to run on three AAA batteries, which can be replaced when depleted. The aluminium alloy body can be wiped clean with a dry cloth. The tail clickie switch has a simple on/off action. There are no stated consumable parts other than batteries. The 21 LED UV light source is fixed within the housing. The 95 mm length and 35 mm diameter make the torch easy to store when not in use. These factors support repeated use across the listed applications without special maintenance requirements.
