Review: This is a powerful flashlight! - Just opened this flashlight and despite not having another UV flashlight to compare this to I would be willing to argue that this one is the best bang for your buck. Pros: - Bright in UV terms - is small and light -most definitely 365nm if not shorter Cons: -Gets hot within 5min -Connection between battery isn't ideal, may need/want to run a wire from tip of spring to connector. -Can not mod/or completely disassemble without the u-shape pin tool (cant remember what they are called) -Is extremely dangerous to skin and eye sight. This is very important for you to know, I feel this flashlight is emitting dangerous levels of UV radiation. I would not under any circumstances point this light at anything reflective that would shine back into your eyes or shine this flashlight at anyone closer than 50ft of you if at all. This is a weapon and should be treated as such. -365nm to my understanding was a safe UV wave to shine at myself or at people for a couple seconds at a time. Now like I said I have just opened this flashlight. I have not hurt myself or anyone else since opening it. I am scared to put this light on my skin and I feel my glasses will be a necessary thing to wear when I am using this light strictly because of the power this thing has. That being said, I do not know how power of the light vs lightwave range effects damage to your body especially at 10 watts -Now I know the flashlight says warning this and that but my understanding is that 365nm is a UVA light that would have a tough time giving you a tan even under long exposure times. This flashlight will melt your vision in seconds. -I have never purchased anything in my life so underrated. To achieve their supposed 365nm they put a filter over the LED that only allows short wave to pass through the lens. Which is really confusing because of the extensive research I did prior to buying this flashlight have convinced me that you need quarts to achieve such short waves so I had my doubts about this method. Which begs the question, what nm is this flashlight actually capable of with a quarts lens and how short of wave can or is this LED capable to achieve? My guess is an extremely dangerous levels. Not sure if this is actually a con... Recommendations to AloneFire: -This flashlight needs more cooling -Would love to see this in a C8 flashlight with a quarts lens Final thoughts: I got these flashlights for cheap and they do exactly what I need them to do and my worry of a buying a cheap flashlight that could not achieve 365nm was immediately put behind be as soon as I turned it on. Build quality was as expected for a cheap flashlight (good enough). Would highly recommend this flashlight with an extreme caution of the warnings listed above. Hope this helps
Review: Way better than expected! Lights up scorpions like beacons! - Pro's: * Can see a scorpion from a good 20ft away * Lights them up even in cracks in the walls (they'll even shuffle around because of the amount of light they are emitting!) * Puts off hardly any visible light, mainly just luminescences anything that can. Some things will light up a room based on the light they emit from it! * I can't really see needing a brighter light for backyard/house scorpion hunting * Rechargeable battery Cons: * You should wear some kind of plastic eye covering when using it. Just the bounced back near invisible light seems to make my eyes really strained after 10 minutes of using it (but using clear safety lenses gets rid of that) * Gets warm fairly quickly- not super hot, but glad the case is aluminum, and dissipates heat- this LED burns through some power! Summary: Best black light I've used, and I have a different 100 LED light I had bought previously that's 1/20th as useful (a lot more visible light making it harder to see luminescence, and things glow at 1/10th the brightness, and only about 10ft away). I would get this again for sure. I was considering getting the 3 LED version, but it's much more expensive, and would only be more useful if you're looking for stuff further than a 20-30ft backyard.

## Questions & Answers

**Q: Will this lamp set uv adhesives?**
A: Yes, it quickly cures Loctite & Henkel light-cure adhesives, like 4306 Flashcure - But it's not a 10W lamp as advertised.  It's maximum power is 6.66W.

**Q: Made in china?**
A: Yes, made in China. I've had mine for several months. The flashlight is not very useful in daylight, but it works amazingly well in dim light/total darkness. I an very happy with the build-quality and luminescence.

**Q: Is this really legit 365nm?**
A: It must be, it really lights up dog urine spots, even in filtered daylight

**Q: Can you use a 18650 4000mAh battery?**
A: Yes. All 18650 series batteries will work. That is, as long as the + end has the small button as opposed to being flat discs at both + and - . The model # is the key indicator of proper fit. All 18650's are of the same size. The mAh # simply indicates the length of time the battery will last. (milli-amp-hours) The larger this #, the better. A 4000 is a strong battery compared to a 2600.

### ⭐⭐⭐⭐⭐ Very good longwave flashlight
*by D***N on December 18, 2025*

I have bought this flashlight several times over the past 5 years. I have had no problems with them-very sturdy, easy to recharge, good longwave performance. I never tested how long the battery lasts bc I keep multiples around, but it seems to be fine. I don’t use it outdoors much nor to prospect, but it’s a great light, and the price can’t be beat.
