How an Ultraviolet Blacklight Flashlight Unveils Mysteries
The ultraviolet blacklight flashlight has become a great tool in revealing hidden items toresearchers and investigators, and lay tradespeople in a number of occupations. The blacklight flashlight shines ultraviolet (UV) light on substances with fluorescent properties, causing those to glow. These substances are otherwise invisible to the naked human eye, and in fact the fluorescent effect is greatly reduced, if not entirely masked, when white light is present.

An ultraviolet blacklight flashlight thus unveils secrets and mysteries. Many of these secrets are intentionally hidden from plain view, such as watermarks, and some occur naturally, like the spectral properties of gemstones.
Ahead of the recent developments in light emitting diode (LED) technology, a somewhat bulky apparatus would have been required to generate the sufficiently powered black light for these particular applications. Nevertheless the high luminous efficiency of contemporary LEDs permits strong, bright UV light inside a flashlight easily locked in the palm of a single hand, rendering application implementation practical and convenient. For instance, Simon Flashlights sells a UV Blacklight Flashlight that is powered by three AAA batteries and uses 14 small LEDs to focus the ultraviolet beam.
Let’s now examine a number of the many applications now using this modern device.
In this high-tech society which we have been a part, proving the authenticity of government currency and documents has become a significant challenge. Precision counterfeiting is fairly sophisticated, requiring ever more complicated countermeasures. Embedded holographs and watermarks are types of such countermeasures.
Tellers in banks and clerks in stores often think it is a job necessity to check for these embedded markings inside the currency passed before them. They are doing so through a small UV LED flashlight, that causes the markings to fluoresce. (In this instance, the effect is bright enough to not be masked by surrounding white light.) Inside a similar manner, TSA personnel validate your passport or driver’s license.
A favorite application for your ultraviolet LED flashlight will be the detection of urine along with other bodily fluids, both from humans and from animals. The black light doesn’t trigger fluorescence with any strength until the substances are deposited after the containing fluids have evaporated, even though the amino acids and salts suspended in these fluids possess fluorescent characteristics.
Cat owners use UV LED flashlights to ferret the out-of-way corners where their pets have urinated. The fluorescence has an amber color. Restaurant inspectors make use of the lights to examine for rat food and infestation contamination. Hotel inspectors (and picky guests) examinecarpets and sheets, and mattresses for cleanliness through an ultraviolet flashlight.
A novel application for blacklight flashlights is scorpion hunting. The Southwest is more or less overrun through the arthropods, and lots of residents are diligent about capturing them. Being nocturnal, scorpions are very difficult to get during the day, plus they scamper away from ordinary white-light flashlights. But the UV flashlight causes their exoskeletons to fluoresce in a blue-green color, which makes their capture quite simple.
Gemologists analyze jewels to figure out their value. Often significant sums of income ride on their judgments, which derive from if the jewel has been heat-treated, has flaws, or possibly is synthetic. Traditionally their work has required expensive laboratory equipment, but an LED ultraviolet flashlight has proved to be remarkably reliable for this work, particularly for preliminary analyses. The imperfections associated with each type of precious stone fluoresce within a unique way.
There are more applications we haven’t even mentioned. Naturally, the flexibility from the LED ultraviolet blacklight flashlight broadens daily.
