ALONEFIRE SV003 10W 365nm UV Flashlight Portable USB Rechargeable Woods Lamp Black Light for Pet Urine Detection, Resin Curing, Scorpion, Fishing, Minerals, Cure Glue, Bed Bugs with Battery, Charger

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 shorterCons:-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 lensFinal 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

It does exactly what it says. I got it to find pee spots left by my sick elderly cat, who has sadly since passed away from cancer. It works a million times better than the longer wave UV lights on the market, which barely even made urine spots visible and I was still having to crawl on my hands and knees (probably through cat pee) to find them. Like it's not even a close comparison, the 365nm light lit up my house like a CSI crime scene and is a clear winner.If anything it works too well, because it illuminates every trace of dirt in my house, including where my lazy house painter didn't clean the walls and now all the gross stains are entombed beneath a layer of paint for all eternity. But somehow this flashlight sees through the paint and makes them glow, to my dismay of my OCD.It also illuminates other cool things like jewelry (fun science fact - many common gems like diamonds and rubies fluoresce under UV.)I suggest wearing UV eye protection while using because it's that flipping strong and you don't want to burn your retinas out.

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 batteryCons:* 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.
