UV flashlight guide

UV flashlight– for geocaching

The UV radiation had been discovered by the two researchers T. P. Blunt and A. Downes in 1878 or the causal relationship between the UV radiation and the growth of the microorganisms. The research went on and on and new areas were discovered. Among the recent technical achievements is also the UV flashlight , This advance, of course, many discoveries were made on the use of UV light for a variety of applications. The most common is the UV flashlight used today for geocaching, so a leisure activity, in which one lives in the great outdoors.

Flashlight for the treasure hunt

A flashlight is needed if you go to search for clues or treasure hunt in old buildings without electricity or in tunnels or caves. Everything is possible with geocaching and is offered by various providers. The UV flashlight occurs in different variants. In some cases, even very small UV flashlights are used key Chainfit. But even the larger version in real form of a flashlight can be used. It is necessary UV flashlight especially the so-called night cache, a very popular form of geocaching. The UV flashlight can help detect ultraviolet-sensitive surfaces, which is not possible with a conventional LED flashlight. Especially when geocaching objects are known to be specially marked, which can then be illuminated with the UV flashlight, resulting in further directions.

Mode of operation and range

A UV flashlight also works with LED light. But this emits light with a specific wavelength of 395 to 400 nanometers (nm). The peculiarity of the UV flashlight is that the ultraviolet waves are not actually visible to humans, but are visible through the illumination of the UV flashlight. Especially when geocaching, it is also useful to use a UV flashlight, because their radiation from the other „players“ is not detected. But if you use a normal flashlight for geocaching, you will lose it immediately, because it is detected very quickly by the emitted rays. Something detrimental may be that this type of flashlight has only a very short range. The price difference is noticeable here very quickly. There are also UV flashlights, which can continue to shine. A small keychain UV flashlight, however, has only a range of 1 to 3 m and is therefore not suitable for a night cache. Anyone who buys a UV flashlight, should take care that these with batteriesIs provided. Replacement batteries should always be at hand. The smaller UV flashlights have no possibility to change the batteries.

What to look for when buying?

When buying a UV flashlight, care should be taken to ensure that the wavelength is correspondingly large. Because the larger this is, the closer the effectiveness of such a flashlight to a normal flashlight. A bit of money you have to invest in a good UV flashlight already. But such a branded flashlight does not have such high mark-ups as computers and smartphones do today. But the somewhat high-priced products are usually the better ones. Ultimately, of course, should pay attention to the size of the UV flashlight. A UV flashlight for the keychain also brings no performance. The UV flashlight should also be as handy as possible, so ideally ergonomically shaped.
