There are different ways a hobbyist may use a UV LED flashlight. Insect hunters, gemologists, and ghost hunters all use UV flashlights to see things that are difficult to see with the naked eye. Businesses, plumbers, cleaning companies, and dentists all use UV lights as well in some interesting ways.
Businesses
With all of the technological resources available, forgers have been able to recreate impressive documents that are difficult to separate from the legitimate article. Businesses need to stay one-step ahead of these con artists who are trying to profit from their illegal work. One way this is possible is with a UV LED flashlight. There are watermarks and special inks that will only appear under UV light. By examining a document with these special flashlights, it is easier to separate legitimate and forged documents.
Security for special events is easier to handle using UV light. If a company is holding an event that has an elite guest list, security can distribute special bracelets or use hand stamps that will react to UV light. This way, it is difficult for unwanted guests to enter the event.
Plumbers
There are times when a leak is difficult to trace. As the water runs its course down a pipe it can seem like the water is everywhere. By using a special dye, a UV light can help a plumber trace a trail of water to find the source of the leak.
Auto mechanics also find UV LED flashlights as a valuable way to discover the source of a leak. With all the different components of a vehicle and the distance, leaks sometimes travel; it isn’t always easy to see where a leak comes from. In addition, some of these leaks come from a source so small, called a pinhole leak, that it is impossible to see it with the naked eye. Mechanics use UV to find oil leaks, cooling system leaks, and leaks in an air-conditioning unit.
Dentists
This field of medicine has made great strides over the last few decades. It is now possible to “bake” white fillings on a tooth with a UV flashlight. This makes for a more cosmetically appealing repair for individuals who have cavities on teeth that are visible when a person smiles. The filling dries and hardens in less time than a silver filling, making repairing a cavity a tolerable procedure for dental patients.
