These blacklight flashlights can be powered for hours with 2 standard AAA batteries. Made with durable aluminum, this torch can survive accidental drops, temporary water submersion, and perform reliably under any condition. This blacklight flashlight is meticulously engineered for rough handling. It can easily be packed into your purse or travel bag, or you can use the removable pocket clip to attach it to your belt, shirt, or pants pocket to take it everywhere you go. This lightweight, portable pocket-size ultraviolet light is ideal for outdoors, while traveling, and even for casual use around the house. Quickly spot scorpions or use it to authenticate currency, official identification cards, and passports. These UV light pocket flashlights are designed for hotel room inspections, revealing unknown human and pet fluid stains, bed bugs and rodent contamination, and hidden carpet spots that can’t be detected by the naked eye. Since we cannot see phosphors under normal human eyes, we need to rely on ultraviolet light to spot them, and the black light makes this possible. The UV light flashlight work by revealing phosphors – a substance that emits and glows under UV lighting because of radiation. This multi-functional device can also act as a nail dryer. Detecting scorpions, authenticating currency, ID cards, and passports are just a few of the blacklight flashlight applications. For beverage control, a portable, small UV light can slip in a pocket.The UV flashlight black light is the perfect tool for uncovering dogs and cats dry urines, rodent stain, and hidden spots that are left undetected under natural human eyes. In high-patronage clubs, amusement parks and swimming pools, applying quick drying readmission inks can be read easily by UV light. One can detect repair in paintings and rugs using UV light, as differences can be seen between the chemical composition of newer inks, paints, and dyes and that of the originals. UV fluorescence can show overpainting or retouching and identify types of stains. UV or black light reveals changes on the surface of objects as it causes specific fluorescence in materials depending on composition and age. Blood, urine, semen and saliva can present visible fluorescence. UV light is used to detect the presence of trace evidence in forensic investigations. Illegal dumping can be tracked at night using UV light. Ambient light must be minimized for use of UV light at a fire scene. Volatile hydrocarbons such as gasoline, grease, paints and others fluoresce when exposed to UV, and can be seen as fragments of incendiary devices. Their evidence is not always visible as they are absorbed by the fire but UV light can expose them. In arson detection, accelerants' fluorescent glow is greater when exposed longer to heat. Some minerals and gemstones have brilliant fluorescence under longwave UV light. Color and intensity of the fluorescence can identifty many materials. UV Light can react with the chemicals of a mineral specimen and cause it to glow, called fluorescence. paper currency has embedded stripes which will fluoresce under ultraviolet light as follows: $5 glows blue, $10 glows orange, $20 glows green, $50 glows yellow, and $100 glows red. Alterations of legal documents such as careful erasure or ink eradication and altering paper textures are detectable with UV light.Īuthentic U.S. Many newer credit cards have an invisible imprint on the front. Forgeries will glow under UV light and bona fides will be completely dull. Using lower wattage blacklights (4 watt) require being close to the inspection area with it as dark as possible.įorgeries of bank notes, standard checks and travellers' checks are mainly printed on inferior bleached paper or photocopied. Since the UV light is relatively weak, it works best to darken the room as much as possible. The urine will glow in the dark using a blacklight (longwave UV light). The amber-colored pet urine is composed of protein metabolism waste products, with feline diets typically protein richer than dogs. Return Policy: Ultraviolet lamps from Analytik Jena (UVP) have a 20% restocking fee. Replacement 6" BLB type LW tube bulb is optionally available. A nylon strap is attached for easy handling. Lamp is lightweight and small enough to fit into a pocket. It is an excellent lamp for office or quick field inspection. This Model UVL-4 Mini UV lamp uses a 4-watt fluorescent tube with a wavelength of 365nm. Assay - Crucibles, Cupels and Casseroles.
