Specifications Bulb: 3 x 365 nm UV-LED Material: Aluminium alloy Purple Light Wavelength: 365 NM Dimensions: 147 mm (length) x 55 mm (head) x 31 mm (tail) Weight: Approx. 206 g Working time: 3 - 4 hours Charging time: 3 - 4 hours (Charging requirement: 5V-1A/2A) Powerful multifunctional applications The UV light can detect stains or liquids that are invisible to the naked eye on the ground or even on grass. For example, for detecting fake documents, money checking, detecting amber and jewellery, detecting animal urine and stains. In the dark environment, the detection effect of the UV lamp is clearer and easier to recognise. As the torch has a high power and heats up strongly when in use, which leads to a high temperature, it is recommended to turn off the torch after a few minutes to cool it. Full metal housing High-quality aluminium alloy is used for the housing, which significantly improves heat dissipation and makes the torches more reliable and durable. Tips 20 W power is so powerful, so it will produce more heat than a common UV torch, this is a normal phenomenon. Important: Over time, the heat will become very serious. To protect the lamp bead, the torch is designed to reduce its power to 60%~70% of the rated power after 3 minutes of use. USB rechargeable Supports USB direct charging, no charger required. You can charge it via the power adapter, computer, power bank or car charger. The charging port is a USB-C port (type C) that supports reverse plugging to make your charging process more convenient. The package contains a high capacity rechargeable battery. The high battery capacity supports the high performance and long-term output of the ultraviolet torch. Battery polarity Polarity of the battery when using: The positive (+) ends of the battery are attached to the front (closest to the lamp) and the negative (-) ends to the back of the torch. Charging indicator (charging requirement: 5V-1A/2A) Red: ChargingGreen: Fully ChargeCharging Time: 3 - 4 hours Tips: If the torch battery is too low (the light is weak), it is recommended that you charge it in time to avoid damage to the battery due to over-discharge. Features Dimensions Portable and compact case, very easy to carry and use. Dimensions: 147 mm (length) x 55 mm (head) x 31 mm (tail). Net weight: Approx. 206 g 365 nm ultraviolet radiation Different wavelengths in ultraviolet light lead to different visual effects. The wavelength of 365 nm (visual effect of white light) and the wavelength of 395 nm (visual effect of violet light) are in the range of ultraviolet rays. 365nm ultraviolet radiation is better to detect.
