UV flashlights are one of those tools that pull double duty, useful for spotting pet stains on carpet and just as valuable during a late-night paranormal investigation. If you’ve been searching for a Lowes UV flashlight, you already know Lowe’s carries a solid lineup from brands like Kobalt and Craftsman that won’t drain your wallet.
At Haunt Gears, we test and review gear that investigators actually use in the field. UV flashlights rank high on that list because they can reveal trace evidence and surface anomalies that standard light sources miss entirely. That makes picking the right one more than a casual purchase, it’s a practical decision that affects what you can and can’t detect.
Below, we’ve pulled together six UV flashlight options currently available at Lowe’s, broken down by brand, price, and real-world usefulness. Whether you’re checking for scorpions on a back patio or scanning a reportedly haunted location, this list will help you find the right fit without the guesswork.
1. Kobalt Blacklight 51 UV LED flashlight
The Kobalt Blacklight 51 UV LED flashlight is one of the most accessible picks in the Lowe’s UV flashlight lineup. It’s a straightforward tool built around 51 UV LEDs that emit light in the ultraviolet spectrum, making it capable of revealing substances completely invisible under standard white lighting conditions.
What it is and why it stands out
Kobalt built this flashlight specifically for detection tasks where a regular flashlight comes up completely empty. The 51-LED array gives you wide coverage across a surface, which is a real advantage when you’re scanning a large area quickly. Most UV flashlights at this price point use far fewer LEDs, which means a narrower beam and more back-and-forth passes to cover the same amount of ground.
The higher the LED count, the more surface area you cover per pass, which matters whether you’re chasing stains, scorpions, or something harder to explain.
Running on 3 AA batteries, this flashlight stays easy to power during extended field sessions without requiring you to hunt down specialty cells. Kobalt also builds to standard durability expectations, so the housing handles rougher conditions that come with outdoor use or working through older structures during a paranormal investigation.
Best uses
This model works best in any scenario where you need to cover ground quickly and light conditions are already low. The most practical applications include:
- Pet stain detection on carpet, hardwood floors, and upholstery
- Scorpion detection during outdoor nighttime sweeps
- Leak tracing with fluorescent dye in HVAC or plumbing systems
- Paranormal investigations to reveal surface residues and markings invisible to the naked eye
- Counterfeit detection for currency, documents, and security seals
What to check before you buy
Before you commit to this as your primary Lowe’s UV flashlight, confirm the wavelength output listed on the packaging. The Kobalt Blacklight 51 typically emits around 395 nm, which sits at the visible edge of the UV spectrum. That range handles most stain and scorpion detection well, but if you need deeper UV penetration for more sensitive forensic or investigative work, a 365 nm model produces stronger fluorescence on a wider range of materials.
Also confirm whether batteries are included before you walk out of the store. Kobalt sometimes ships tools without them, and discovering that at midnight in a remote location wastes time and goodwill fast.
Price at Lowe’s
The Kobalt Blacklight 51 UV LED flashlight typically retails between $15 and $25 at Lowe’s, placing it firmly in the budget-friendly tier without cutting corners on LED count. Prices shift with seasonal sales and clearance cycles, so checking the current listing on Lowe’s website before you make the trip is worth the extra two minutes.
2. Police Security 2AAA UV penlight 395 nm
The Police Security 2AAA UV penlight is the slim, pocket-sized option in this roundup, built for anyone who wants a capable UV light without committing to a full-size flashlight. It’s the kind of tool you clip to a bag or shirt pocket and pull out exactly when you need it.
What it is and why it stands out
This penlight runs on two AAA batteries and emits UV light at 395 nm, which covers most common detection tasks without any complicated setup. The narrow form factor means it won’t sweep a wide surface area the way a 51-LED model does, but that’s not its purpose. What it gives you instead is precision and portability in a package that fits anywhere in your kit.
If you need to zero in on a specific spot quickly rather than sweep an entire room, a penlight gives you more targeted control than a wide-beam flashlight.
Best uses
This model suits situations where lightweight carry is the priority over broad coverage. Strong use cases include:
- Hotel room spot-checks for surface stains and residues before settling in
- Document and currency verification at close range
- Paranormal investigations where you need a backup UV source that adds no real weight to your pack
- Quickly re-checking areas flagged during a wider sweep
What to check before you buy
Confirm that 395 nm output meets your specific detection needs before you purchase. This wavelength sits close to visible violet light, so some materials won’t fluoresce as strongly as they would under a 365 nm source. Also check the expected battery life rating on the package, since two AAA cells drain faster than larger battery configurations under continuous use.
Price at Lowe’s
The Police Security 2AAA UV penlight typically retails under $15 at Lowe’s, making it one of the most affordable picks across the entire Lowe’s UV flashlight selection. Verify current stock and pricing on the Lowe’s website before making the trip, since availability varies by location.
3. Police Security 6AAA UV flashlight 395 nm
The Police Security 6AAA UV flashlight steps up from the penlight version with a larger body and six AAA batteries powering a stronger UV output at 395 nm. This model gives you noticeably more range and brightness than a two-cell penlight, which translates directly to better surface coverage when you’re scanning an area under low-light conditions.
What it is and why it stands out
Where the 2AAA penlight handles precision spotting, this six-cell version is built for extended use and wider beam coverage. The additional batteries give it both longer runtime and stronger sustained output, so you won’t find yourself swapping cells mid-investigation or mid-job. It’s still compact enough to carry comfortably in a kit bag, but powerful enough to serve as a primary UV source rather than just a backup.
More battery capacity means you get consistent output across longer sessions, which matters when you’re mid-sweep and can’t afford to lose intensity at a critical moment.
Best uses
This model fits investigators and homeowners who need reliable UV coverage over extended periods without constant battery swaps. Practical applications include:
- Scanning larger rooms during paranormal investigations without losing beam strength over time
- Pet stain detection across wide floor areas in fewer passes
- Leak tracing with fluorescent dye across plumbing or HVAC runs
- Outdoor sweeps for scorpions around structures or in yards at night
What to check before you buy
Confirm the exact LED count and beam angle listed on the packaging before purchasing. A wider beam angle improves area coverage, while a narrower beam focuses intensity on smaller zones. Since this is a Lowe’s UV flashlight sitting in the mid-range tier, also verify in-store stock on the Lowe’s website before making the trip, since regional availability varies.
Price at Lowe’s
The Police Security 6AAA UV flashlight typically runs between $15 and $30 at Lowe’s, depending on current promotions. Check the Lowe’s product listing directly for the most accurate price before you visit.
4. CRAFTSMAN UV LED miniature flashlight
The CRAFTSMAN UV LED miniature flashlight brings a trusted tool brand into the UV detection space with a compact form factor that makes it easy to carry during investigations. This is a Lowes UV flashlight pick that appeals to anyone who wants something small, reliable, and backed by a recognizable name without paying a premium for it.
What it is and why it stands out
CRAFTSMAN designed this miniature flashlight to deliver UV output in the smallest possible package without sacrificing practical usefulness. It fits easily in a jacket pocket, making it one of the most convenient options in the Lowe’s lineup for quick grab-and-go access during field investigations or household checks.
When space in your kit is at a premium, a miniature UV flashlight you’ll actually carry beats a larger model sitting in the truck.
Best uses
This model fits targeted detection tasks rather than wide-area sweeps. Its compact size works well across several scenarios:
- Hotel and rental property checks for surface stains in tight spaces
- Spot-checking specific zones flagged during a larger sweep
- Counterfeit detection for currency and documents at close range
- Carrying as a backup UV source alongside your primary investigation flashlight
What to check before you buy
Confirm the wavelength and LED count on the packaging before buying, since miniature models sometimes trade raw output strength for a smaller body. Battery drain is another factor worth checking, since compact units running on AAA or button cell batteries deplete faster under continuous use than larger configurations.
Check the Lowe’s website for in-store stock at your location before making the trip, as regional availability on CRAFTSMAN miniature tools varies more than you might expect.
Price at Lowe’s
The CRAFTSMAN UV LED miniature flashlight typically retails under $20 at Lowe’s, making it accessible for casual investigators and homeowners. Pricing shifts during seasonal promotions, so confirm the current figure directly on the Lowe’s product listing before you head out.
5. CRAFTSMAN UV LED flashlight 2-mode
The CRAFTSMAN UV LED flashlight 2-mode takes everything the miniature version offers and adds a dual-mode design that switches between UV output and standard white light. For investigators who want fewer tools eating up space in their kit, this is one of the more practical picks in the Lowe’s UV flashlight lineup.
What it is and why it stands out
This flashlight gives you two distinct lighting modes in a single unit: ultraviolet for detection work and white light for general navigation and note-taking. That means you stop digging through your bag mid-investigation every time you need standard illumination. The CRAFTSMAN build quality also holds up under the regular handling that field work demands, making it a reliable tool rather than something you treat carefully to protect.
Having both UV and white light in one tool cuts down on kit weight without sacrificing what you can actually do on-site.
Best uses
The 2-mode design suits situations where you move between UV scanning and standard visibility without stopping to swap tools. It handles these tasks particularly well:
- Paranormal investigations where UV detection and basic white light are both needed in a single carry
- Pet stain detection across carpet and hard floors in low-light rooms
- Household leak checks using fluorescent dye in plumbing lines
- General navigation in attics, crawl spaces, and dimly lit areas during field sessions
What to check before you buy
Confirm the UV wavelength on the packaging before purchasing, since CRAFTSMAN doesn’t always list it prominently in store displays. Also verify how the mode switch operates, whether it cycles through a single button or uses a dedicated toggle, since that affects how quickly you can change modes during active use.
Price at Lowe’s
This model typically retails between $20 and $35 at Lowe’s, which reflects the added functionality of the dual-mode design. Check the current product listing on the Lowe’s website before visiting to confirm stock at your specific location.
6. Fleming Supply 51 UV LED black light flashlight
The Fleming Supply 51 UV LED black light flashlight rounds out this Lowes UV flashlight guide as a high-LED-count option that prioritizes wide surface coverage over a compact form factor. If you’ve been comparing it directly against the Kobalt Blacklight 51, this model gives you an alternative at a similar LED count from a different brand, with its own housing and ergonomic choices worth weighing before you buy.
What it is and why it stands out
This flashlight delivers 51 UV LEDs arranged to sweep large surfaces quickly, making it one of the better options in the Lowe’s lineup when coverage speed is your main priority. The wide array means you get broad beam distribution across floors, walls, and upholstery in fewer passes than any penlight or single-LED unit could manage.
A 51-LED count at this price point gives you investigator-level surface coverage without the cost that typically comes attached to professional-grade gear.
Best uses
The Fleming Supply 51-LED model fits any situation where scanning area matters more than pinpoint precision. Strong applications include:
- Paranormal investigations that require full-room UV sweeps in dimly lit locations
- Pet stain detection across wide carpeted areas or hardwood floors
- Scorpion detection during outdoor nighttime sweeps around structures or in yards
- Counterfeit currency and document verification at close range
What to check before you buy
Confirm the wavelength output on the packaging before committing to a purchase, since 395 nm and 365 nm models produce noticeably different fluorescence results depending on the materials you’re scanning. Also verify the battery type and total count required, since a 51-LED array under continuous use depletes cells faster than lower-count models during extended investigation sessions.
Price at Lowe’s
The Fleming Supply 51 UV LED black light flashlight typically retails between $15 and $30 at Lowe’s, positioning it close to the Kobalt 51-LED model in the budget-to-mid range. Check the current Lowe’s product listing online before your visit to confirm stock at your nearest location.
Next steps
Each Lowes UV flashlight on this list solves a specific problem, and the right pick depends entirely on what you plan to do with it. If you need wide surface coverage, the Kobalt Blacklight 51 or Fleming Supply 51-LED model gives you the beam spread for full-room sweeps. If portability matters most, the Police Security penlight or CRAFTSMAN miniature fits in any pocket without adding noticeable weight to your kit.
