best uv flashlight

If you’ve used a flashlight at least once, you probably know how important it is to have the best UV flashlight.

It’s the most helpful piece of equipment to use when looking for something in poorly lit areas while camping, hiking, etc.

However, have you ever used a UV flashlight? Maybe you’ve seen it in movies or the ambulance without knowing how handy it can be in your everyday life.

We reach for our flashlight at the first sign of a power failure. Flashlights are more practical than candles and aren’t as messy or dangerous. In general, they light our way, but UV models have a different role.

Often referred to as the blacklights, these do not emit a black light. Instead, they talk about an ultraviolet one that can be used in several ways.

How Do UV Flashlights Work?

UV light works by showing phosphors – A substance that reveals visible light when pointed at by a black light.

The human eye can only see a portion of a UV light spectrum, and it’s precisely that portion incorporated in a UV flashlight. Awesome, right?

That portion is the thing that gives a UV flashlight its unique role. If you were to turn one on in a dark room, you might find a hidden note and a wide variety of hidden stains. But, of course, it’s perfect if you have a pet.

What Makes The Best UV Flashlight?

You want something robust, easy to use, and ideally lightweight.

Since you’ll often be using them indoors, it doesn’t matter if they’re waterproof, but it always helps. But, of course, you also want flashlights to be powerful enough to illuminate a large area.

Typically, UV flashlights aren’t sturdy and only light up a small circle, so you need to hold them close to the surface you’re illuminating.

The more expensive ones tend to illuminate more surface area and save you lots of time when you’re using them.

What Are UV Flashlights Used For?

Flashlights can be used to locate and identify a variety of substances. For example, if your pet urinated on your carpet, and it dried out before you saw it, you could find a stain by smell.

Fortunately, a UV light allows you to see these stains to find and clean them more effectively. In addition, it’s cost-effective in the long run since you wouldn’t have to steam clean the entire carpet or hire professional cleaners.

You can use them in hotel rooms to check for cleanliness before settling down. It’s also great to have a cleaning agency and check on how well your employees clean the area.

Use it to find bacterial residue, semen, urine, wine, saliva, and body oils. Its unique abilities and versatility made UV models skyrocket into modern world popularity.

Other Uses For UV Flashlights

You may find it helpful if you live in an area prone to scorpion infestation. These tiny arachnids can easily be seen with a black light, which is excellent if you’re a fan of camping. It’s also suitable for mineral hunting since some minerals glow under UV light.

Black lights can check fine details in most currency notes, and official documents since most have security strips. In addition, if you take large amounts of cash payments, a small UV lamp will enable you to check any bill.
