How an Ultraviolet Blacklight Flashlight Unveils Mysteries
The ultraviolet blacklight flashlight has become an invaluable tool in revealing hidden items toinvestigators and researchers, and lay tradespeople in numerous occupations. The blacklight flashlight shines ultraviolet (UV) light on substances with fluorescent properties, causing them 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 mysteries and secrets. Many of these secrets are intentionally hidden from plain view, such as watermarks, and some occur naturally, such as the spectral properties of gemstones.
Ahead of the recent developments in light emitting diode (LED) technology, a fairly bulky apparatus might have been required to generate the sufficiently powered black light for such applications. But the high luminous efficiency of recent LEDs permits strong, bright UV light inside a flashlight easily held in the palm of one hand, rendering application implementation practical and convenient. For instance, Simon Flashlights sells a UV Blacklight Flashlight which is powered by three AAA batteries and uses 14 small LEDs to focus the ultraviolet beam.
Let’s now examine a few of the many applications now using this modern device.
In this particular high-tech society which we are a part, proving the authenticity of government currency and documents has become a significant challenge. Precision counterfeiting is very sophisticated, requiring ever more complicated countermeasures. Embedded watermarks and holographs are samples of such countermeasures.
Tellers in banks and clerks in shops often think it is work necessity to examine for these particular embedded markings in the currency passed before them. They actually do so by means of a small UV LED flashlight, that causes the markings to fluoresce. (In this case, the impact is bright enough not to 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 amino salts and acids suspended in these fluids possess fluorescent characteristics, although the black light doesn’t trigger fluorescence with any strength until the substances are deposited after the containing fluids have evaporated.
Cat owners use UV LED flashlights to ferret the out-of-way corners by which their pets have urinated. The fluorescence posseses an amber color. Restaurant inspectors make use of the lights to examine for rat infestation and food contamination. Hotel inspectors (and picky guests) examinesheets and carpets, and mattresses for cleanliness through an ultraviolet flashlight.
A novel application for blacklight flashlights is scorpion hunting. The Southwest is essentially overrun through the arthropods, and several residents are diligent about capturing them. Being nocturnal, scorpions are very difficult to get during the day, and they also scamper from ordinary white-light flashlights. Nevertheless the UV flashlight causes their exoskeletons to fluoresce inside a blue-green color, and this makes their capture quite simple.
Gemologists analyze jewels to find out their value. Often significant sums of money ride on the judgments, which are based on whether the jewel has been heat-treated, has flaws, or 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 related to each type of precious stone fluoresce within a unique way.
There are more applications we haven’t even mentioned. Naturally, the versatility from the LED ultraviolet blacklight flashlight broadens daily.
