I’ve been playing with it putting it against my trusty 97 lumen mini Maglite for a couple of days and unless something pops up, here’s what we’ve got:
It’s extremely bright, but a fairly narrow beam. Pretty much the same aperture as my Maglite but more intense.
Learning to use it is a little bit of a curve. It’s a two seconds press to turn it on. Single quick press after it’s on to cycle brightness between low, medium, and 600 lumen eye hurting power.They’ve included a map that also appears to indicate that you can also press two seconds to get to strobe and SOS mode. For those I’ve found that I have to press two seconds to turn on, then press and hold for maybe 4 seconds more for it to power off and then cycle into the hidden modes.
There’s also a five second lock press for the times when you think you’ll somehow trigger it with a two second push but not any longer. To disable that just press for five seconds.
The head can swivel 90 degrees and the light is balanced well enough and has a flat enough back that you can put it on a table and probably aim light wherever you want. The swivel is machined well enough that I was unable to get my skin caught in it while I was actively trying to get my skin caught in it. This is a beef I had with an ex-light of mine.
There are three things I do not like about this. The first being that it comes with a belt clip and not a belt holster. The position of the clip means the flashlight can’t hang with most of the body down. Personal preference for me is that no lights can be bent into by gut or side gut.
The second thing I don’t like is that jostling the Nano Torch Twist can turn it off. This means if you drop your flashlight while running from Old Man Smithers who’s wearing a zombie mask to scare away customers and close down the park so that he can work a deal with developers, you’re going to have to trust that your canine friend can find the dropped flashlight in the dark.I’m able to have it shut off about once every six drops from standing. It’s always when it lands on the head or the tail, never on its side.
The awesome memory features comes in as my third complaint. It remembers the last setting on the low, med, high. The next time you turn it on it’ll be at that setting. For me this resulted in expecting low and getting high a couple of times which may not sound like much but when you’re crawling around under a desk and expecting ~200 lumens and you get 600 it’s not pleasant.

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.
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:
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.
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.
