About this item

  • 51 LED & 395nm Wavelength: Our black light flashlight is equipped with 51 upgraded strong ultraviolet light LEDs and emits ultraviolet light at a wavelength of 395 nanometers, which can reveal stains or fluids that could not be detected with the naked eye. The upgraded ultraviolet light LED can show fluorescence staining more clearly, enabling you to locate the affected areas effectively, perfect for doing some deeper cleaning.
  • Dependable Material & Thoughtful Design: This UV flashlight is made of ultra-intensity LEDs and aircraft-grade aluminum alloy housing, which is hard-anodized for strength and durability to withstand accidental drops or bumps. The aluminum alloy body also helps to dissipate heat effectively to ensure the longevity of the UV light. The non-slip textured handle design provides a comfortable grip while helping to prevent the flashlight from slipping out of the hand, reducing the risk of dropping.
  • Compact Handheld Size & Portable: The black light measures 5.8” x 2.2” and 6.1oz in weight, small and lightweight enough for one-handed operation. The compact size also makes it easy to store and carry, taking up minimal space in a pocket, handbag or toolbox. The UV flashlight comes with a wrist strap lanyard, provides a hands-free carrying option, you can wear it on your wrist or hang it from a hook. Additionally, the lanyard can help prevent accidental drops or loss of the UV flashlight.
  • Efficient Detector & Multi-function Tool: The ultraviolet blacklight can work great for pet urine detection, kitchen stain detection, bathroom stain detection, leak detection, resin curing, UV glue curing, finding scorpions, finding uranium glass, lighting up UV paint, discovering minerals and detecting fluorescent agents, security code, counterfeit documents, money verification. It is an indispensable helper and a versatile tool in your life.
  • Easy Installation & Sealed Design: Powered by 3*AA batteries (Not Included). No need for any complicated operation, simply press the button to turn on/off the flashlight.

  • The ultraviolet led black light can work in natural light but the effect is subtle. It works best in a dark environment, the darker it is, the better it works.

  • The effectiveness of the blacklight flashlight for detecting pet urine depends on the urine's concentration and dryness. Fresh pet urine, partially-dried pet urine, and certain absorbent surfaces may weaken or even prevent the UV light from glowing.

  • The pet urine contains phosphorus and protein (mainly phosphorus) that will fluoresce under UV light, making it visible. Some cats on a low phosphorus diet can cause their urine to be low in phosphorus, making it undetectable with a UV flashlight.

  • The human eye is less sensitive to UV than visible light. 395nm is in the UVA range outside visible light, even if emitting the same energy, it will appear dimmer to our eyes. But it can detect fluorescent materials invisible under normal light.

Bought these to use when searching for yooperlites on Lake Superior! They've worked very well and have resulted in some solid finds👌🏻

They’re not too bright, but are perfect for hunting scorpions. We had a ton of them in north Texas, last year. These black light flashlights are awesome. You can also use them to find urine stains. My neighbor’s dog kept peeing on my front porch. I used these lights to find the exact spot that I needed to spray bleach cleaner, in order to eliminate that nastiness.

I bought a two pack for the price of 1 by other vendors. They are surprisingly sturdy aluminum, not plastic. Strange battery setup takes 3 AA batteries not a C cell but works. Works really well with new batteries. I accidentally put in weak batteries in one and you could really see the difference in brightness. New batteries made both pretty bright. Good for a distance of a 10+ feet to make things glow, but is directional so only lights up where you point it, up to a few feet across at 10 feet distance. Usually you would use it much closer but should work well for a walk in the woods at night.I used them to show the UV dye in car coolant while looking for a leak. The UV dye glowed bright yellow.Also used in a motel to spot dirt. Did NOT find any bedbugs and the sheets were clean, but I was amazed at the smears on the microwave and all the dust that had not been cleaned next to the fridge, in various crevices, in the folds of the old mattress (looked below the liner), on the lounge chair, in drawers. I then used it on my car seat, and complaining about the motel is the pot calling the kettle black. Be prepared emotionally if you use it to look for dirt / dandruff in places you have not cleaned. It's also fun looking at the glow in the dark effect of things around you. My old dark wood desk finish glows a faint green in this light. Overall, a product that works and a good value in a two pack.

Let me say straight away that these black lights work great. Solid, good viewing area, does the trick. However… know that if you buy these you will be tempted to use them throughout your house. Word of advice: DON’T DO IT! My husband and I have not slept a wink since we cut the power and used these throughout our home. We discovered that our dog has expelled fluids across the majority of our living room. Our toilet area resembles the splash pad at the base of a children’s bouncy house. My husband apparently aerosolizes his urine and the the walls of the bathroom look like a college rave. The only thing missing is the psychedelic music. He’s like the Jackson Pollock of pee. I will not even tell you what our teenage son’s room looks like. Bottom line…Great black lights at a good value… but you’ll never sleep again!

Let me put it this way...the dog is sorry I made this purchase. I can now easily see where she pee'd when we weren't looking.

These work well but are not at all bright. Wish they were a bit brighter.
