Description: M2 UV flashlight is also called black light, adopts high efficiency pure 365nm UV-A LED with the LED radiation flux of 2060mW . The flashlight body is compact with a steel clip included as an accessory, powered by 1 piece of Li-ion battery, compact and portable. The visible wavelength range to human eye is 400-700 nm, while the dominant wavelength of the M2 flashlight is 365 nm with less visible light, so the M2 is not "bright" in eyes and it's not designed for use of illumination. From which it proves that it's pure 365 nm wavelength with a better performance than the ultraviolet light of other wavelengths (380-400 nm). Flashlight includes 1 * 18650 battery preinstalled AND a single cell external battery charger Tested with Weltool UB18-35 Rechargeable Lithium Battery: Low radiant flux mode High radiant flux mode LED Radiant flux : 630mW 2100mW Spectral radiosity @38cm(15in) : 5900μW/cm 2 15500μW/cm 2 Irradiated area (round) diameter of distance @38cm(15in) : 20cm Central beam (round) diameter of distance @38cm(15in) : 6cm Visible spectrum illuminance distance@38cm(15in) : ≤ 13Lux ≤ 43Lux Runtime(h) : Until radiosity falls to 10% 10h25min 4h20min M2 "Purple Beard" is a professional-grade UV detection flashlight, which is more suitable for professional fields: UV curing : Some curable adhesives specify the 365nm UV for rapid curing, M2 UV flashlight can also be applied to ink curing field, such as printing, oil painting and wood instrument processing. Forensic investigation & evidence collection : Proteinaceous materials emit fluorescence when illuminated by UV light. So M2 can be used to check the body fluid, blood, fingerprint, fiber and also to analyze the bite mark and bruise. UV light usually is used for detection of fraudulent documents such as ID card, visa, passport, credit cards or banknotes. The UV light can be used for arson investigation though the spattering of chemical combustibles and used for car theft forensics by identification of car ID label, and also for vehicle accident analysis. Non Destructive Testing (NDT) : M2 is a compact flashlight especially suitable for on-site fluorescence penetrant testing and fluorescent magnetic particle inspection of special equipment in ships, pressure vessels, draught fan blades and other narrow spaces. Leaks detecting : By the fluorescence reaction of ethylene glycol in the cooling system, M2 black light can be used to check the leaks of the car radiator and the air-conditioning refrigerant by adding a fluorescent agent. And it works on detecting engine leaks and oil pipeline leaks. Ore exploration : Some kinds of ore cannot be quickly identified by the naked eye, but they present various colors under UV beam and can be quickly noticed. It also applies to screening of gems, amber and jade, artifacts, antiques, and discovering traces of fraud and glue. Hygiene : Riboflavin validation in pharmaceutical companies, inspection of human body fluids and other tissues pollutants in public places, cleaning of oil stain, and the presence of traces of urine from rodents such as rats in the warehouse. Home : Find pet defecations, oil or contaminant in kitchen and bathroom, check sanitary products, clothing, cosmetics, paper towels with fluorescer. Outdoor activities : The outer shell of the scorpion glows under the M2 UV flashlight's beam, making it easy to find even in the dark. Many mushrooms and flowers, fruits, seeds or some insects, bees, and small crabs are more magical under the illumination of M2 than at night or in daylight. M2 series have 3 models: M2-OL (Even-beam), M2-CF (Focused high radiation beam), and M2-BF (Focused pure beam), no matter you are a law enforcement officer, mechanic, engineer, maintenance person or workman, warehouse manager, outdoor enthusiast, laboratory researcher, M2 "Purple Beard" can be a good helper! Operation instruction(M2-BF): Turn counterclockwise to open the back cover, put the positive terminal of the charged 18650 high-quality lithium-ion battery into the flashlight toward the light head, and then turn clockwise to tighten the tail cover. The flashlight has reverse polarity protection. If the battery is inserted in the wrong direction, the flashlight will not be damaged, but it will not work. If this happens, check the battery. After installing the battery, lightly press (half-press) the tail switch button once to turn on the flashlight and release the switch to turn off. After the flashlight is turned off for more than 10 seconds, the default is low output mode every time it is turned on. In the non-open state, continuously press the flashlight tail switch, the mode is switched from low to high cycle. When any mode is turned on, press the switch hard (full press), there will be a "click" sound, lock the current brightness is always bright; press again hard, the switch has a "click" sound, the flashlight is turned off. When the battery voltage is too low, the flashlight will flash a warning, please replace with a new battery. After flashing the prompt, the flashlight will automatically turn off at any time to protect the lithium ion battery from excessive discharge. Caution: Unauthorized disassembly may damage the flashlight and void the warranty. Weltool "Total Heat Dissipation" technology will dissipate the internal heat of the light during operation, it is normal to feel the flashlight body temperature rise. Please check and replace the O-ring regularly to maintain the waterproof rating. Please check and lubricate the threads regularly with professional lubricant. Clean the contact surfaces regularly to keep the flashlight normal operation. If irregular strobe or failure to turn-on occurs, the contact surfaces may be dirty and requires cleaning by using alcohol cotton swabs. Remove the battery from the flashlight during long term storage. This flashlight is not intended to be used as a diving light. Do not aim the flashlight directly at eyes. Keep out of the reach of children.
