April 27, 2022 6 min read

UV flashlights are a great piece of technology. UV lighting was first created in the mid-1800s when scientists discovered that sunlight reflected off certain minerals could be used to create light. 

Perhaps you've heard of it and are considering buying a UV flashlight, or perhaps you're just interested in the concept and want to know what they can be used for? 

Either way, we've compiled a short guide that will aim to explain everything you'll need to know about UV Flashlights. We've also included a short FAQ section at the end of this article to help you understand some extra issues regarding this topic! 

Let's shine some light into the world of UV flashlights!

What Is A UV Flashlight?

A UV flashlight is simply a flashlight with an added UV component. This means that it has been modified so that it emits ultraviolet (UV) light instead of regular visible light. It is important to note that UV lights do not emit any heat, which makes them ideal for use during winter months as well as other times when there may be a risk of frostbite. 

UV flashlights have been around since the early 1900s but were only really popularized by the 1990s. They are now widely available and many people enjoy using them for various reasons.

How Does UV Light Work?

The main reason why UV flashlights exist is because of their ability to penetrate through clothing and skin. This is useful for those who like to take part in outdoor activities such as camping, hiking, fishing, etc. 

The reason why these flashlights are so effective is that they allow you to see objects under your clothes without having to remove them. This is especially helpful if you're wearing thick layers of clothing. You can even use a UV flashlight while swimming or snorkeling.

What Are UV Flashlights Used For?

In this section, we are going to answer our original question of what UV flashlights are used for. We're going to be taking you through each use and explaining them in detail.

In The Home

First up, let's talk about how they can be used in the home. If you live alone and don't have anyone else to share your space with then you might find yourself wanting to keep things tidy and organized. UV flashlights can be used to illuminate dark areas within the house. These include cupboards, behind pictures on walls, in the corners of rooms, etc. By shining the light directly onto these areas you can make sure that they stay neat and clean.

If you have pets then UV flashlights can be very useful too. Pet owners often struggle to get the right amount of light out of their regular household bulbs. UV flashlights allow you to easily adjust the brightness level to suit your needs. This means that you can ensure that you give your pet enough light to play with toys and interact with you, whilst still being able to see them clearly when needed.

Another thing that UV flashlights can be useful for is cleaning. Whether you're trying to clean a window, a mirror, a sink, or anything else that requires you to shine a bright light on it, UV flashlights can be extremely handy. Many people find that they can use them to quickly spot leaks from pipes or water damage on windows.

In The Garden

Another common place that UV flashlights can come in handy is in the garden. When you're gardening you often have to move around a lot and it can sometimes be difficult to see all the plants that you're working with. By using a UV flashlight you can easily identify weeds and pests that you may otherwise miss. You can also use it to check whether your flowers need watering or fertilizing.

When it comes to gardening, UV flashlights can also be used to protect plants against insects. Insects can cause a lot of damage to your plants and will usually leave signs of their presence. By using UV light you can easily detect the presence of bugs and prevent them from spreading further.

In The Office

Finally, we'll finish off talking about how UV flashlights can be put to good use in the office. As mentioned above, one of the most common uses for UV flashlights is illuminating dark areas within the house or office. However, they can also be used to help you read documents more comfortably. Documents such as receipts, contracts, bank statements, etc., tend to look much better when illuminated by UV light.

You can also use them to read maps or road signs at night. This is particularly useful if you're driving at night because you won't be blinded by the headlights of other cars.

Medical Uses Of UV Light 

UV radiation has been proven to kill viruses, bacteria, fungi, and even cancer cells. It's no wonder why so many hospitals now use UV lights to sterilize medical equipment.

There are two types of UV lights: germicidal (or germ-killing) lamps and germicidal irradiation units. Germicidal lamps emit ultraviolet rays which destroy germs, while germicidal irradiation units emit both visible and UV rays.

Germicidal lamps are typically used to disinfect surgical instruments, bandages, and hospital beds. They must be placed close to the patient to effectively sterilize the area.

Germicidal irradiation units are generally used to disinfect air, food, surfaces, and objects. They work best when used in conjunction with an ozone generator. Ozone generators produce oxygen molecules that combine with harmful microorganisms and neutralize them.

It is worth noting that a UV flashlight won't do any of this, though they are sometimes used to detect things that other light may not. 

Final Thoughts

So there we go! Those were some of the most common uses of UV flashlights, both within the home and in a more clinical setting. If you're looking at getting your UV flashlight, what is written above is some of what you can expect. 

We hope that you now know why people buy UV flashlights and how they can be useful at home, in the garden, or in the office. If you're looking for some extra information around this issue, check out our FAQ section below.
