Pros: Large head with 52 bulbs, so it casts a wider and stronger glow. Plus, the flashlight is rated for IPX4 protection (meaning it can resist splashing water). It’s also vibrant, thanks to the 51 UV led bulbs it has.
This allows you to search an area more quickly and efficiently.
But the head of the flashlight is large, casting a wider beam. It has a narrow metal grip with a knurled texture, making it easy to hold.

For more professional applications, you might opt for 365 nm, which offers greater fluorescence. 395 nm is closer to the visible light spectrum, whereas 365 nm UV is “deeper” into the UV spectrum. UV light falls within the 10 to 400 nm range, but with most blacklight flashlights, you’re looking at just two numbers in that range: 365 nm and 395 nm. UV light begins below 400 nanometers, or nm. You might not expect to need a physics lesson when picking out a UV flashlight, but it is important to have a baseline familiarity with wavelengths. What To Consider Before Buying a UV Flashlights And if that’s all terribly dull, just get one of these for your next party to show off your glowing gin and tonics. Since some coolants have phosphors added (like the aforementioned antifreeze) you can use a black light to potentially detect leaks.

That means that a black light can be a handy thing to keep around to quickly authenticate bills. Some banknotes are marked with luminescent strips, including US 20 dollar bills.

Scorpions aren’t the only pests you can detect using a black light.
But you might not have realized that scorpions glow under a black light, too - this can be helpful if you live somewhere where scorpion infestations might happen. You might associate bioluminescence with animals that live in water, such as jellyfish.
When living organisms emit light, that’s known as bioluminescence. This helps block out unwanted visible light that can come from the bulb and overpower the luminescence (this filter also has the added benefit of making it look cool). That’s an additional filter that’s added to the bulb of black lights. One fact you may not have known about black lights is that the distinctive blueish purple glow doesn’t actually come from the UV light. And yes, many body fluids can be detected using a black light. Antifreeze, some rocks and minerals, tonic water and even olive oil emit some light under a black light. There are natural and manmade items that are fluorescent, also called phosphors - these glow under a black light because they absorb and reflect the ultraviolet light back at you. Just make sure you brace yourself for what you might find. A UV flashlight black light can help you detect all sorts of messes you can’t see, allowing you to properly clean trouble areas. One of the most unexpected cleaning tools you can have in your arsenal is something you might associate more with raves and haunted houses, and that’s a UV flashlight black light.
