Unlike that of a regular flashlight, the role of a UV flashlight isn’t so much to provide you with a light in the dark but rather to reveal what is missed with the naked eye. It is easy to forget that what we see in our everyday life isn’t quite the objective fact we like to think of it as, with colors, for example, being somewhat of a subjective interpretation.

What we see is directly tied to how light refracts off objects, creating the color we perceive. While the color of a wavelength is an objective measurement, the colors we perceive are not. The perception of color is even different between species.

Sometimes we need a bit of help at seeing things that may not be highlighted or made visible through traditional wavelengths of light. A UV light does a great job at providing us with a visual insight into refraction that we don’t see from regular sunlight or lighting that falls outside of the extreme ends of the light spectrum.

You’re undoubtedly familiar with the term fluorescence, which is the word given to something that exhibits traits that cannot be seen with regular light. Fluorescent objects will require a UV light to ‘decode’ – and its uses range from simple fun to exploration and even security and forensics.

UV flashlights may be able to offer you a glimpse into a world usually hidden from sight. And best of all, they can be acquired for an affordable price and bring unique and useful functionality that you don’t find with other devices.

uvBeast V3 UV Flashlight

A high-powered and effective UV flashlight that stands out from the competition.

How UV Flashlights Work

UV (Ultraviolet) is a form of electromagnetic radiation that falls outside the visible spectrum, with a wavelength between 10 nm and 400 nm. UV lights like the above-mentioned UV flashlights don’t offer a visible beam of light. Instead, it gives off photons that react with the phosphorous to make the phosphorous visible. What you see under UV lights is the reaction of the phosphorous, creating visible light.

This means that you’re not going to get the same kind of illumination as you would using something like a tactical flashlight. Instead, you’ll be purchasing a UV flashlight in most cases solely for the UV functionality.

Understanding the Difference Between UVA, UVB and UVC

Before you can purchase the right UV flashlight, it is important to understand what nm is and how it affects the light you purchase. Nm is short for nanometers. Ultraviolet light, or ultraviolet radiation as it is also known, covers the range from 10nm’s to 400nm’s. It can be broken down into these specific segments:


Covers the range 315 – 400nm’s. Known as long wave UV and is not absorbed by the ozone layer.


Medium wave and covers 280 – 315nm’s. The majority f this is absorbed by the ozone layer.


Covers the range 100 – 280nms. This is short wave and is completely absorbed by the ozone layer.

You can discover more about the entire range here.

The only range that humans can see is the top part of the long-range; hence, an ultraviolet flashlight should be within the top end of this range. All the UV flashlights on this list are rated at 395nm’s as this will allow you to see the stains while maximizing the efficiency of the light and life of the batteries.

You’ll notice the visible spectrum separated from the rest of the electromagnetic spectrum in the image above. UV light falls just to the left of the visible spectrum, with infrared on the right. Below, we can take a further look into the UV side of the spectrum in more detail.

The Purpose of UV Flashlights

We now understand how they work, but what exactly are they used for, and why would you need one?

Authenticity Checking

Fluorescence is used to manufacture government documents and banknotes to help detect fraudulent copies or counterfeit cash. When you go to the bank, you may have seen that the teller will wave the notes under a light while processing them; the light being used is a UV light. There will typically be fluorescence within the security strip of bills that won’t be visible to the naked eye but will show clearly under UV light. Similarly, with documents like passports, fluorescent fibers embedded in them will become visible under UV light.

A UV flashlight, in turn, is a great way to scan over bank notes or documents to see whether or not they are legitimate. It is a useful tool for someone who wants to ensure that they are never in possession of counterfeit banknotes, something that happens now and then through currency circulation outside of the bank.

Finding Traces of Body Fluid

Perhaps not the most pleasant of uses, but one that can offer some beneficial insight into the quality of a particular garment or even hotel room. Urine, semen, and saliva all contain traces of fluorescence which can be picked up under UV light. A common use is looking for pet urine stains or finding body fluid in a shared space.

Crime Scene Investigation

UV light has become a handy tool for forensics detectives who need to comb a scene for evidence. Not only are bodily fluids detected via UV flashlight, but so are tooth and bone fragments. Of course, the professionals in the FBI are going to be using state-of-the-art equipment which uses UV light. However, a UV flashlight can definitely still reliably offer some of these functions and is sometimes employed by private investigators.

Gemstones & Minerals

You may wonder how something that, in so many cases, already looks spectacular directly from the ground could get even cooler. Well, some gemstones and minerals have a few hidden tricks up their sleeves that we never get to see. There are actually over 500 different types of minerals that have been found to contain fluorescence.

Aside from just seeing the stone in a new light (no pun intended), a UV flashlight will also allow you to identify fake gems that are supposed to contain fluorescence. Once again, UV light comes to lend us a hand in avoiding getting scammed by providing a method of verification.

Finding Animals

While the presence of fluorescence exists in several species, a UV flashlight isn’t going to be of much use for something like the Flying Squirrel, which, while glowing under UV light, probably isn’t going to be within arms reach of the curious flashlight holder.

Instead, UV flashlights are often used to detect Scorpions or certain insects. Scorpions glow a bright blue under UV light for reasons that science has yet to uncover. While these mysterious little Arachnida species are often hard to detect, heading out to the desert at night with a UV flashlight could give you a whole new experience.

In addition to the Scorpion, insects like centipedes, millipedes, and crickets can all respond with color changes under UV light thanks to their fluorescence.

Is UV Light Dangerous?

The dangers of UV are something that most people are aware of or have at least heard discussed. But just how well aware are you of what poses the risks and what it takes in terms of exposure for it to harm your health?

Thankfully, using a small handheld UV light such as a flashlight is unlikely to have any real impact on your health, assuming you use it practically and avoid looking directly into it for extended periods. In fact, we recommend always avoiding looking directly into flashlights of any kind.

Though as far as the carcinogenic nature studied concerning UV exposure, the sun remains our biggest threat. While most UV flashlights will primarily be UVA, the sun radiates UVB light, which is stronger and at higher risk of causing skin cancer. Tanning beds are another manufactured application that has been shown to increase cancer risks among those who frequent them.

Health Warning

You may not be able to see UV light, but that doesn’t mean it’s not there. Do not shine these flashlights intentionally into somebody’s face or look directly into the light.

Our Selection of the 10 Best UV Flashlights:

Now that you have an understanding of how UV flashlights work and what they are used for, let’s take a look at some of the best UV flashlights on the market so you can find what is best for your intended purposes.

1. uvBeast V3 385-395nm UV Flashlight

  • LEDs: 3
  • Wavelength:
  • Weight: 13.3oz


The uvBeast V3 offers a distinct change from many of the other popular UV flashlights on the market. Traditionally, we’ve seen a lot of UV flashlights using large quantities of low-intensity LEDs. Instead of following this approach, the uvBeast V3 offers fewer, but higher quality (SMD) LEDs in order to achieve excellent brightness while at the same time ensuring a smaller device to work with.

One of the gripes we’ve had with the products we’ve looked at in this field is that you are almost forced to make a trade between portability and brightness. This flashlight offers both. The wavelength on this flashlight is also adjustable, meaning that you can tweak it to your requirements.

What we really love about the uvBeast V3 though, is that the company has opted for two rechargeable 18650 Lithium-ion batteries. This is a huge step up from most competitors on the market which in many cases don’t include batteries but often stipulate that their devices should not be used with rechargeable batteries. So while the uvBeast V3 comes in at a higher price point initially, the savings from batteries alone, over time will compensate for that higher price.

If you’ve handled a UV flashlight before, you’re probably familiar with how they don’t quite feel the same as a regular flashlight. You’re almost always very limited in the range that the beam is thrown, and in many cases, you feel more like you’re handling a limited source of light. The uvBeast V3 ultraviolet flashlight manages to not only offer blacklight functionality, but it can cast the UV beam quite a distance! The manufacturer claims that more than 70 feet of beam distance are achievable, a feat rarely accomplished by even the best UV flashlights.

While the best performance is going to come from low-light environments, the uvBeast V3 also manages to illuminate stains under typical interior and ambient lighting, a testament to the strength of the beam.

We’re big fans of the way uvBeast creates new iterations of their products as the market and the times change. The V3 steps ahead of the competition, in offering a device that is both rechargeable and provides quality UV light, that could be used to detect pet stains, illuminate certain animal species as well as manage document authentification. We find the uvBeast V3 an excellent choice for those trying to locate scorpions at night, the long beam range provides a safe distance while still ensuring you find what you’re looking for.

We would have liked to have seen waterproofing available on this device, as that is one area where we feel it may fall a little short.

The uvBeast V3 365nm Variant

It is also worth adding that uvBeast offers a similar flashlight, but with a wavelength of 365nm. These 365nm UV flashlights tend to be less common and are specifically intended for more commercial purposes. So if you’re on the market for something in the 365nm range, we can definitely recommend taking a look at the uvBeast V3 365nm UV flashlight.

  • Rechargeable Batteries (Included)
  • Bright
  • Impressive Beam Distance
  • Adjustable Wavelength

2. Escolite 51 UV Flashlight Black Light

Escolite UV Flashlight Black Light
  • LEDs: 51
  • Wavelength: 390-395nm
  • Weight: 10.1oz


The Escolite 51 UV flashlight gets its name from the 51 LED diodes that emit blacklight at a wavelength of between 390nm and 395nm. This wavelength is somewhat standard for ultraviolet flashlights and does well in picking up strains, as well as illuminating fluorescent animals or banknotes. It consumes a modest 3 watts of energy, which is a good thing because the company recommends against the use of rechargeable batteries. Instead, you should use 3x regular AA batteries with the Escolite. The manufacturer states that improper battery usage will void the warranty, so be sure to follow their instructions.

When it comes to the build quality of the Escolite 51 UV flashlight, we were a bit surprised to see that it’s waterproof sealed, something that isn’t too common in even the best UV flashlights.

The Escolite 51 contains three distinct segments. The front element includes the LED chips, power button, and the antislip grip; the battery compartment, and then the rear cap which is where one changes the batteries. The construction of the flashlight is aluminum alloy, which while not the strongest material out there, is already better than some of the plastic options out on the market.

The brightness of the Escolite 51 UV flashlight is impressive for its price point and allows you to quite easily pick up on dried animal urine on most surfaces (excluding reflective surfaces and carpets that are themselves fluorescent. You are even able to identify some fluorescent objects from feet away using this flashlight, which is something you often don’t find on your corner store UV flashlights.

In terms of performance, you get decent range on the light with the best distance typically being around a foot from the target. You will pick up on dried animal urine quite easily in the dark, and easily spot markings on banknotes. While it is capable of detecting scorpions, we do prefer the performance of some of the other products on this list for that purpose.

This isn’t as strong as some other UV flashlights on the market, but the price point is very affordable and if you’re looking to venture into the fluorescent world, this is not a bad place to start. However, if you’re looking for something with a bit more juice, there are more expensive options that could get you greater results.

  • Affordable
  • Waterproof
  • Decent performance in low light

3. LE Ultraviolet Flashlight

LE Ultraviolet Flashlight
  • LEDs: 9
  • Wavelength: 395nm
  • Weight: 2.19oz


The LE Ultraviolet Flashlight is a compact and affordable UV flashlight that is intended for consumers who are looking at purchasing a UV flashlight but perhaps aren’t interested in the most functionality or output. In short, this is intended to fit the budget market, and for around $10 – you’ll be hard-pressed to find many other blacklight flashlights at this price point.

The batteries are easy to fit, the end of this flashlight screws off, and a small carriage can be slid out. Add the three batteries with the positive and negatives indicated on the carriage and then slide it back in. Screw the base back into position and test by turning it on. When new, it may have a protective cover on this carriage; you will need to remove this to ensure the electricity can flow from the batteries to the LEDs. That’s all there is to getting started.

Instead of one textured piece, this flashlight has two. They are situated at each end of the ultraviolet flashlight and designed to fit against the palm of your hand and your fingers. This should help to ensure you don’t drop the flashlight when you need it the most. It has 9 LEDs and operates on the same frequency range, 395nm. The 395nm wavelength, as we’ve touched on, is fairly standard for entry-level UV flashlights and should suit most needs that aren’t commercial.

This flashlight is also IPX4 rated, which means you can use it in the rain without any issues – a feature that is appreciated at such a low price point. The single switch for activating and deactivating the light is mounted on the end of the torch.

The LE ultraviolet flashlight arrives with a comprehensive 12-month warranty; it has a ROHS Certification to provide you with peace of mind regarding the quality of this product. It can be used to detect gas leaks, water leaks, urine stains, verify Identification documents or confirm currency is genuine.

There is also a handy wrist strap that helps you when you’re using the flashlight in tricky situations, one such example would be when you’re under a car trying to identify an oil leak.

When it comes to construction, the primary material is aluminum alloy, which as we’ve seen is fairly standard for UV flashlight construction. Unfortunately, we did note that some other customers have encountered some issues with quality control on the build. Thankfully, the company is true to their warranty and will typically resolve any issues should you find yourself as one of the unlucky customers who receive a product with issues.

The light itself uses 5W to power the LEDs, but you will need to set your expectations in line with the pricing and size of this product – as you will not get a lot of distance on your beam. This extends into use in an ambient-lit room, you will need to ensure that you have minimal environmental lighting in order to get the most out of this product. This is really where you will find the limitations of cheaper blacklight flashlights.

  • Affordable
  • Water-Resistant
  • Compact Size
  • 12-Month Warranty

4. Kobra UV 100 Black Light Flashlight

Kobra UV 100 Black Light Flashlight
  • LEDs: 100
  • Wavelength: 385-395nm
  • Weight: 12oz


The head is so large because it has 100 LEDs, far more than any of the others on this list, and part of why this UV flashlight will cost you a bit more than some of the competitors. It works on the same frequency, 395nm, as the previous offerings but has 18 watts of power. Impressively it still manages to weigh just 9.3 ounces.

The flashlight is approximately 8 inches long by just less than 2 inches wide. However, the large head is approximately 3.5 inches in diameter. This makes it a little harder to carry the light discreetly in your hand. The beam of this light in the dark should carry 25 feet and be roughly 8 feet wide.

This is impressive by any standards and makes it the most powerful blacklight flashlight on this list. Of course, all this power requires additional batteries; the Kobra requires 6 AA batteries to provide this huge beam of light.

These can be fitted by unscrewing the rear end and sliding out the battery carrier. Insert the batteries, paying attention to the correct polarity, and then slide the carriage back in and screw the base back on. You will need to purchase batteries separately as they do not come with this light.

The flashlight itself is made from machined aluminum and is designed to be waterproof as well as shockproof. The bulbs should last for 100,000 hours; that’s a lot of stain searching! Your average set of batteries will last 20 hours; you will need to change them a few times in the lifetime of this light. This is one UV flashlight used by many law enforcement agencies and forensic teams worldwide. Kobra offers a 1-year money-back guarantee.

They will refund your money if you have any issues with this ultraviolet flashlight within the first 12 months of ownership. This is how confident they are in their own product.

The main issues associated with this flashlight revolve around inadequate light or a failure to pick up urine. Assuming that these are stains and not fresh, these are items that the comprehensive 12-month money-back guarantee would cover. As most people find this to be a powerful and useful ultraviolet flashlight, it is fair to state that, apart from a few isolated cases, this is the most powerful backlight on the list and an effective tool in your arsenal against stains and animal waste.

  • Waterproof and shockproof
  • Powerful Light
  • 12-month warranty

5. VICOUP Black Light UV Flashlight

  • LEDs: 12
  • Wavelength: 385-395nm
  • Weight: 3.52oz


The light itself is the smallest in this selection. Its length is a standard 4.4 inches. You could easily carry this with you in a pocket, your handbag, or just in your hand, without anyone noticing. To illustrate how small this is, it is two-thirds the length of an iPhone 6 and less than half the width, although considerably deeper.

The light takes 3 AAA batteries which are fitted by unscrewing the base of the flashlight. These fit into the dedicated battery carriage, which slides in and out. Batteries are supplied with this light. This design style is prevalent with all types of flashlights.

The base also incorporates the on and off switch. This is just one soft, textured button which you will probably find easiest to utilize with your thumb while holding the light. The flashlight body is made from extremely light aluminum; in fact, this ultraviolet flashlight weighs 4.8 ounces. This might not be the lightest on this list, but it is heavy enough to feel solid in your hand.

You will find 12 LEDs positioned in the front of the light, which should last 12 years! The light frequency is standard, 395nm’s, and you will find a convenient 60-day money-back guarantee; this is long enough to confirm that it works as expected. This is another ultraviolet flashlight that can be purchased at a great price. You will also benefit from the standard 1-year warranty to deal with any issues you might have.

  • Compact
  • Lightweight
  • Reliable

6. Findway 5 UV Ultraviolet Flashlight

Findway 5 UV Ultraviolet Flashlight
  • LEDs: 9
  • Wavelength: 395nm
  • Weight: 6.4oz


The Findway is compact. It measures 3.6 inches long and just 1 inch wide, rivaling the offering from LE on this list. It has 9 LED’s set into the head of the light and produces a powerful beam with just 3 AAA batteries. These are not supplied with the torch. However, for an excellent price, you can get 5 of these ultraviolet flashlights.

This makes them the cheapest backlight on this list, although you do need to buy the set! It is even possible to lower this price if you buy larger quantities.

The batteries are fitted by unscrewing the base of the light to reveal the battery carriage. This slides out and allows you to insert the batteries, making sure you observe their polarities as you do so. The power button is located on the base, ensuring it can only be turned on when the batteries are correctly fitted.

The flashlight is made from aluminum alloy and weighs a respectable 6.7 ounces for all 5! It also incorporates a handy belt clip that will enable you to clip it onto your pocket, bag, or any other item you can think of.

As it looks like a standard flashlight, no one needs to know that you are actually inspecting the cleanliness of their home or workplace. Professionals who need UV flashlights to verify identification will find this pack of 5 lights beneficial; there will always be one to hand. It is worth noting that although this flashlight is splash resistant, it is not waterproof; you should not submerge it in the water!

This product is good value but not the best on the list as one of the biggest issues seems to revolve around dropping the light, which then dislodges the wiring and prevents it from working properly. This is an issue that needs to be addressed; however, considering the price of this product, a little care and attention can help ensure they work when you need them to.  

In general, the quality of the product is better than satisfactory and should provide you with a good insight into the number of stains located around your home. There are guaranteed to be more than you realize! There is no doubt that these are the cheapest on this list and probably the cheapest you will be able to purchase a new ultraviolet flashlight for.

  • Affordable
  • Compact

7. Morpilot 12 UV Flashlight

Morpilot 12 UV Flashlight
  • LEDs: 12
  • Wavelength: 395nm
  • Weight: 0.8oz


The lower half of the light is textured to ensure you have a good grip even when your hand starts to shake with fear of what you have discovered. This is a very effective light when looking for urine stains, checking identifications and currencies, or looking for scorpions.

The Morpilot ultraviolet flashlight is 3.78 inches long by 1.18 inches wide. It has 12 LED’s in the head to provide a good level of illumination. The darker the room, the easier you will find it to see urine stains and other marks which should be on your surfaces; your dog might be in a lot of trouble! The flashlight is extremely lightweight, weighing just 1.8 ounces; you will hardly notice it in your hand or your pocket. It requires 3 AAA batteries to power it; again, these are entered through the light base.

Unscrew it and remove the battery holder. The three batteries should be placed inside in opposing directions; there is a guide to show you which way round each battery should go. Slide the holder back in and carefully screw the base back on to allow the flashlight to work.

It would help if you never tried to take the head of this unit apart as you are likely to damage the LEDs and distort the beam of light. It is possible that long-term exposure to UV light directly into your eyes can cause problems in the long term.  It operates at the standard frequency of 395nm and will illuminate all the stains within your home.

This flashlight is made of durable aluminum, which enables it to be both light and strong. The beam is sufficient that you will be able to pick out any stain on the floor without having to bend. Equally, this flashlight is effective when used on the curtains, work surfaces, or even the furniture in your home. Food stains can be just as much of an issue as animal urine.

The fact that it can also be purchased at an incredible price point makes it a contender for the best value award. The main issues with this UV flashlight seem to be that nothing was visible in the home. If this is the case, then congratulations to this user; they have a spotless home! There are so few negative comments that you can feel safe purchasing this item and discover what mess has really been left in your home and that of your friends. You won’t want to put it down once you have started using it.

  • Lightweight
  • Compact
  • Durable

8. YOUTHINK UV Blacklight Flashlight

  • LEDs: 100
  • Wavelength: 395nm
  • Weight: 11.2


Each of the LEDs is designed to last for approximately 12 years, making this a durable and cost-effective investment. The light itself is made of an aluminum alloy which is both strong and light. Unusually for this type of light, it unscrews more like a conventional flashlight.

The body separates from the head just below the neck, revealing an opening to slide your battery carrier out of. In fact, there are two carriers, and both need 3 AA batteries in them, creating a total of 6 batteries to power this powerful blacklight flashlight. Slide the carriers back in and screw the head and body back together, and your light is ready to go!

You will appreciate the handy hole on the bottom of the light, which allows you to fasten a wrist strap onto your flashlight. This, coupled with the textured anti-slip material coating the light, will help to ensure it stays in your hand, no matter what horrors you see.

The YOUTHINK UV flashlight is 8 inches long, making it the biggest in this collection; the head measures 3 inches, and the main body is a little under 2 inches. This is comfortable to hold and will not be lost easily. However, it is not one that you can slide into your pocket without anyone noticing!

It weighs a reasonable 12 ounces and runs on 18 watts, hence the power and length of its beam. You should be able to spot any stain almost effortlessly, providing you wait for it to be semi-dark. As well as stains, fake money, and scorpions, this black light flashlight can actually help you to tell whether your jewelry is genuine or not.

The flashlight is also built with O-rings in the joins. You must ensure these are in place correctly when you screw your light back together. It is these seals that enable the flashlight to be waterproof, not just splashproof. This product can be purchased for less than $20, making it excellent value for money considering the brightness of the light. Of course, you will probably be happy with the lower-powered models for general use, which is why this does not take the top spot. However, it is a strong contender and a UV flashlight that will meet your needs perfectly.

9. FoxNov 12 Ultraviolet Flashlight

FoxNov 12 Ultraviolet Flashlight
  • LEDs: 12
  • Wavelength: 395nm
  • Weight: 3.17oz


The FoxNov UV flashlight is 3.74 inches long and 1.02 inches wide at the base; this is where the on / off switch is located. You will find this easy to operate with your thumb while holding the flashlight. The LED head is fractionally wider at 1.18 inches; it needs to be this wide to accommodate the 12 LEDs.

This UV flashlight is approved to CE standards and by the RoHS. You can purchase it for an amazing price, and it arrives with batteries; slot them in and start using it. It does have a loop in the base that will allow you to connect strings. This can secure it to your wrist, bag or help make sure you don’t lose it. The UV light will show up urine stains, scorpions, food stains, body products and even allow you to verify that your money is genuine. It weighs 3.2 ounces and is made from aluminum.

This ultraviolet flashlight will help you to locate all the animal trails and behavior that you can’t see normally. It will help you remove unwanted pests and study where your own animals move around when you’re not there. The reviews of this product are generally very favorable. The general issue from those who rated it negatively is that it doesn’t work properly. However, it is difficult to see how these incidents can be anything but isolated occurrences with so many pleased customers.

It is important to remember that these products work best in darker conditions, with lighter carpets, and only with dried urine, not wet. If you attempt to see wet urine, it will show you nothing as it needs to dry to allow the phosphorous and salt to shine in the light; in liquid form, this is not possible.

Your Guide To Buying The Right UV Flashlight

There are several other factors you should consider before committing to a specific UV flashlight:


Most of the flashlights on this list are small, approximately 4 inches long. This means they are straightforward to carry with you. The size of your hand and the position of the grip on the flashlight can also influence the best size of flashlight for you. Larger flashlights may be able to offer you more power through the use of more diodes, though, so make a pick based on what is required for you.

Most of the flashlights in this collection have wrist straps; this is a valuable addition to prevent you from dropping the light and potentially breaking it.


It is quite possible to purchase a black light flashlight for under $10. In fact, this is probably your preferred price range as you can afford to damage or lose it without breaking the bank. However, the saying ‘you get what you pay for’ does carry some weight.

The more expensive UV flashlights will have more power and will generally be robust enough to survive drops and bangs, which the cheaper ones may not survive.

It is unlikely that you need to create a budget for your purchase. Even the most expensive UV flashlights on this list can be purchased for less than $30. However, it is worth considering how much you wish to spend as this will assist you in making your decision.


The intensity of the UV flashlight is an important factor to consider, and it’s not as easy as just looking at the number of diodes in the light. Different LED technology can provide different intensities. That is to say, just because a UV flashlight has a lot of LEDs in it, doesn’t mean that it’s going to outperform one with fewer diodes.

Equally as important to consider is that the varying efficiency offered by different LED types may mean that your UV flashlight is able to put out more light with less battery power than other models.

Because of these difficulties in identifying brightness by the numbers, we’ve done our best to represent which are the brighter options in our list.

Intended Use

Perhaps the most relevant part of your decision is considering what you are planning to use the ultraviolet flashlight for.

For example, you might wish to opt for the most powerful option if you are hoping to see scorpions in your backyard. But if you’re simply looking for a toy to provide your child, you can settle for the weaker, less expensive options.

If you wish to check your hotel room before you stay, you may find that a smaller, less powerful blacklight flashlight is more than capable. This will be more discreet when you arrive at the hotel.

Once you consider your intended use, you will narrow your search parameters to the more powerful or less powerful options.


Almost every UV flashlight in this list has a wrist strap; this ensures you can easily carry it and, perhaps more importantly, avoid dropping your light. This is perhaps the most practical way to carry your ultraviolet flashlight.

However, some come with belt clips; this can be an effective way to carry your light and is worth considering. There is no correct answer to the most convenient ultraviolet flashlight; it is simply the one that will fit your needs best.


It would help if you considered the reputation of the UV flashlight you intend on purchasing. The better-known brands are more likely to supply a quality light.

One of the best ways to verify the reputation of a UV flashlight is to check the manufacturer’s website and see what positive reviews have been left on the site. In addition, it is worth checking Amazon and other social media sites to see what people who have purchased the UV flashlight think of the product. You are likely to have honest opinions through these sites as there is no reason to restrict the comments.

Of course, there will always be some customers who are not happy with their purchase. Before you accept their opinion and base your decision on what they have said, it is important to look at the consensus. This will tell you how good ultraviolet light really is.

It is also worth considering what the flashlight is made from. All those who made this top 10 UV flashlight lists are made from aluminum which ensures they are tough enough to be carried with you and can even survive being dropped. However, some lights are made from plastic. You need to decide if this is the right material for your needs. In general, flashlights made from plastic will be damaged easier, ruining your investment.


A UV flashlight can serve so many purposes, from practical use to entertainment and even security.

It is important to consider your options before deciding which UV flashlight is the right one for your needs. One factor that has been mentioned but can make a huge difference to the effectiveness of your blacklight flashlight is the radius of the beam. In general, the more LEDs you have in the light, the larger the head of the light needs to be and the wider your beam of light will be. However, to be effective, this must be coupled with enough high-quality batteries. This will help you to cover any space much faster than with a lower-powered flashlight.

However, if you deal with smaller items such as washing powder residual on clothes or even dried cat urine, you may prefer to use a smaller radius light. Of course, the larger the radius, the brighter the beam will be when used in close quarters. This can help if the space is exceptionally dark but can also confuse the issue if there are too many other items that will also be picked up by the light, such as fluorescent strips in the carpet.

A UV flashlight is an essential item for every home. In fact, you may prefer to have several options available. Select your preferred one from this list and order a UV flashlight today!
