Flashlights differ in shapes, sizes, and in the functions which they perform. For instance, pocket flashlights are very different from headlamps and even among headlamps, there are many varieties – some are ideal for hunting while others are specifically made for kids. Similarly, ultraviolet flashlight, also known as UV flashlight, fulfill another role.

UV flashlight is also commonly referred to as black light. However, they don’t give out black colored light, the beam produced by them is, in fact, purple.

Although Human beings generally cannot see most ultraviolet lights, there is a very small part of the UV spectrum which is visible to the Human eye. This small spectrum is incorporated into the best UV light. If you’ve seen a UV flashlight, you’ll know that the light is not very powerful. However, this light can show you a wide variety of hidden things that you wouldn’t be able to see normally.

UV flashlight is used by the police and other law enforcement agencies to investigate crime scenes or checking for counterfeit money, but they can also prove useful for detecting things such as pet stains, how clean a hotel room is, and to even hunt for scorpions.

Buying Guide: How to Buy the Right UV Flashlight in 2019?

We’ve given you our top picks for the best UV flashlights to buy in 2019, but before you make your final decision, it’s essential for you to understand what principles the UV flashlights work on. Throughout the article, you must have noticed how ‘nm’ has been repeated again and again. The nm stands for nanometers as ultraviolet light covers the range from 100 nm to 400 nm. This range is further broken down into specific segments which you can read about here.

The range that we, humans can see is between 315-400 nm. Most of the UV flashlights covered here measure somewhere between 390-400 nanometers and this is the top end of this range, and ultraviolet flashlights should be within this range. As only this range will allow you to see the stains and maximize your flashlight’s battery life.

Therefore, make sure you pay attention to the UV light wavelength your desired UV flashlight offers.

Besides the ultraviolet range, there are several other factors you should consider before buying your UV flashlight.

What is the Perfect Size for the Best UV Flashlight?

Most of the flashlights on our list are quite small, but your requirements could be different. Ask yourself; what do you need the UV flashlight for? Are you a traveler and need a UV flashlight that you can take with you everywhere or do you need one just for your home? Compact flashlights are easy to carry but having a larger one is much harder to lose.

Furthermore, the size of your hand and how do you usually hold things will also affect the best UV flashlight size for you. Most of the flashlights on our list have a wrist strap which becomes quite useful in terms of keeping the flashlight safe so you should consider that too.

  • Power

The more powerful your flashlight is, the easier it will be to spot stains. However, powerful flashlights use more battery power and are relatively more expensive. Like how the Kobra UV light is the most powerful one with 100 LEDs and uses six AAA batteries while the others use only three.

This obviously doesn’t make that big of a difference if you are using the UV flashlight occasionally, but for everyday use, it can be quite expensive. Therefore, keep in mind your usage and the power required. In any case, opting for a mid-range UV flashlight is the better option, but again, the main question is how much power do you need?

  • Intended Use

This is perhaps the most important thing to consider before you go on to make your final decision. Ask yourself, where do you plan to use it? If you’re working at a place where accuracy is really important, getting a powerful flashlight would be the better option, so there is no margin for error.

On the other hand, if you’re a traveler and just wish to check your hotel rooms for hygiene then having a smaller UV flashlight would work better as you want to be really discreet as well as easy to carry.

  • Reputation

Another important thing to consider is the company of the UV flashlight you plan on buying. The brands that are popular are more likely to supply a better quality light than the less popular brands. One of the best ways to ensure the company is good is to check their website and look at the reviews. Make sure you take a good look at the reviews for all the flashlights and only after you’re sure that the majority of the users were satisfied, then buy that flashlight.

It’s important for you to check the general consensus of the customers and the total percentage of customers that were satisfied.

  • Price

Lastly, the most important feature to be considered before you make your decision to buy the flashlight is whether you can even afford it. It’s possible to purchase a flashlight under 10 dollars – our top picks have several of those. However, the statement ‘you get what you pay for’ does carry some weight to it.

It’s quite obvious that the brighter flashlights that offer durability and long life will be more expensive. But it’s quite unlikely for you to go through lengths to purchase the best one as even the most expensive UV flashlight costs less than 30 dollars.

In the end, it’s your decision about how much you’d want to spend and what do you want to get in that.


An ultraviolet flashlight can help you ensure you have a clean home. It also helps you identify original documents from fake ones. The flashlights discussed above are currently the best ones available in the market, offering maximum functionalities. We’ve tried to list down all the important factors that can influence your decision to buy the best UV flashlight. We hope you find the perfect one for your use!
