ALONEFIRE SV003 10W 365Nm UV Flashlight Portable Rechargeable Blacklight For Pet Urine Detector, Resin Curing, Scorpion, Fishing, Minerals With Aluminum Case, Battery Charger, Battery Included Review

This item is getting a 3 out of 5 stars. NOT because of the quality of the actual UV light. Pros:Great quality build.Extremely bright output.True 365nm UV output!Lights up everything!Perfect blackout filter lens.Nice and responsive tail switch.Cons:Paid for expedited shipping and arrived with box looking like a kid used it as a step stool.Light comes in a box that’s 7 x 3 x 2 With everything included BUT came in a amazon box big enough to fit an entire large ice cream container it with NO…

I was glad that I read the reviews and got this one instead of the cheaper ones. It is very bright, even though the battery that comes with it is not the full 10 watts of power. In mid brightness I can see it in the daytime, but not in a very brightly lit room. I can find all of the dog accidents and the counterfeit money strip in currency. The places that I previously cleaned were spotless using this flashlight so I knew that I had cleaned those spots on the rug well. I did find doggie…

I used this to find cat pee after my cat peed outside the box. This flashlight is amazing. I’ve used black lights in the past that didn’t show any cat pee at all (and I previously had a 19 year old with dementia and arthritis and kidney disease who had known pee spots). Perhaps those were the wrong wavelength.Anyway, this is great. It’s bright enough that I don’t need to use it in complete darkness, although that helps and the room should be at least semi-dark. Cat pee (and human pee- shine it…

Eagerly I waited for my Alonefire SV003 10W 365nm UV Flashlight to arrive to test it on some minerals I collected. I'm a paleontologist and the UV spectrum of light proves valuable in some scenarios. The minerals even on the low setting with much light around led up with various colors of white yellow orange and green, some colors I have not seen with my previous lamp. This is different , far better than what I previously used, works well and is more than I need for my purposes. The flashlight…

The 365 nm wavelength and black filter lens make such a big difference. If you are like me and go glass hunting in thrift shops, this little light is perfect. It makes spotting reds and pinks much easier due to the lack of blurple light. Green glass is extremely bright with this as well.Pros: Excellent, durable constructionHigh and low light modesCons: 2000 mah battery is a bit short lived. Easy upgrade to a higher capacity 18650.The battery charger is fairly cheap and does not hold the battery

I purchased this to use for oxygen cleaning scuba equipment. This light is perfect! It makes any foreign matter fluoresce brightly. The best part about using this light for SCUBA is that it fits in the neck of tanks & can be suspended from the lanyard, thus giving a much more thorough view inside tanks for 02 cleaning. The light itself isn't "bright" because of the wavelength, but it's not supposed to be! In a darkened environment it is more than strong enough for workbench use. I haven't had…

Few people know or care about why this shorter wavelength activates this air and water sterilizing TiO2 anatase photocatalyst. The fact that anatase can reduce germs to CO2 and water is useful, and this color of light will do it. One can also split water into H-OH with TiO2 and 385nm UV. Other bandgap semiconductors will also become conductive under this color of light. So, one pays a bit more for a well made special light source that is in less demand but does something unique like this. Your…

My first purchase died with a bright purple flash the first time I pushed the button. The replacement has performed well curing Loctite AA 349 (glass-glass). I'm quite impressed by the combination of the glue and this flashlight, but I have to take off a star for reliability of the first purchase. Still, revain immediately replaced the unit, so I can't complain too much. I have no idea about battery life b/c I always charge 18650's before using them.

For a cheap 18650 high output UV flashlight this is perfect. It lights up rocks, uranium glass, bathroom and kitchen stains, and much more even when saturated in visible light. I don't use the charger it came with, and the battery is mediocre. It does get a bit warm, but we know it was designed to. The output is misleadingly "dim." You'll notice the typical eerie blue glow from UV, but unlike longer wavelengths (ie:405nm) this does not appear violet and you cannot actually see the light. As…

I use this light for counterfeit bill detection. It lights up the UV band in the bills even inside a brightly lit store. It also works for some ID's. Unfortunately it gets very hot when in use. I've had this accidentally activate while in my pocket leading to a very warm pocket. The battery charger provided does work.Pros:Counterfeit detectionSmall and light weightHas a low power and high power modeRechargeable batteryCons:Gets very hot

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…

Super bright light is actually 365nm unlike other cheap LEDs. Works really well for finding minerals that fluoresce under long wave UV, I mainly used it for sapphire and calcite identification/mining. It has a battery that lasts for a really long time (charger included) for a light that uses so much power that it gets hot. You will see something on the ground from using it while walking at hand height, and can see the glow of a super-fluorescent item (like a hilighter) from 8-10 ft away.It will

this thing is awesome it cures my uv resin hard in like 30 seconds . I love that its rechargeable ive had mine for a wile now and still going strong

It is exactly what I wanted. There were so many negative reviews from people who just didn't know what they were buying that it almost made me skip this item. The 365nm light is not supposed to be seen with the naked eye, but so many people said it wasn't bright enough. This light pinpoints every single speck of dust that will fluoresce. I found spots I didn't really want to find but that also made me have to think about what I found. I found the spots I was looking for and more. You need to do

I agree with Mr. Bonanno's review. This robust device is everything you want and more than you want. In dark, fluorescent materials readily visible. What you want to see will be easy to see. The light, because of its wavelength and intensity, reveals many fluorescent spots that probably are not of interest. Two minor negatives: recharger is more equipment to store and it does require common USB port. Also, bulb end of flashlight (marked "Hot") does get warm after several minutes of use. I…

I have ordered two of these 6 months apart and they both have quality control issues. They work but can’t say I recommend getting one

By far the best black/UV light source I have used. When I saw the pictures people posted of the scorpions etc. I was impressed, but thought it might be a trick of the camera or something. But when I got it and tried it out it was clear that it was high quality. The best thing is it gives off practically no visible light what so ever. If I shine it at my white painted wall that is not UV reactive, at most you see a slight grey light, but it has to be dark in the room to see it. When it's pointed

It is excellent for fungi and lichen observation. I like it a lot and use it for some identifications. Overall, a great purchase

Don't get in your eyes! I bought it to fluoresc my flow toys but won't be using it for that anymore as other people don't understand the dangers and at a rave people don't listen they just grab it and was hard to explain to them cos they didn't understand. Will only use it for other things now.

This is true to the description and very affordable compared to most other 365nm uv lights. Compared to 400nm uv lights, 365nm is king.
