## Overview

The ALONEFIRE SV003 is a compact, 10W UV-A flashlight engineered with a hard-toughened optical lens to deliver pure ultraviolet light at 365nm. Featuring dual output modes for versatile scanning, it excels in pet urine detection, medical screening, mineral identification, and security verification. Its rechargeable lithium-ion battery charges conveniently via USB, housed in a durable anodized aluminum body designed for professional portability and precision.

## Description

Tips: The lamp is 10W, but in order to control costs, the included battery only can make the flashlight work at 6.6W, you can use a higher 3.7v Rechargeable Battery to achieve the full 10W UV lighting results.

## Features

- Pure Ultraviolet Beam: Hard-toughened black optical lens filters out almost all visible light so the light stays within the UV-A range; fluorescent marks, dye residue and invisible ink show up clearly under the beam without a visible violet wash
- Two Output Levels: 10 W high mode for wide-area scanning and 3 W low mode for close-up inspection or longer run time; both controlled by a single tail switch
- Multiple Detection Uses: Wood's lamp screening for ringworm, cat pee and dog urine on carpet, mattress or sofa, scorpion and bed bug hunting after dark, banknote and passport checks, fluorescent mineral and rock identification, and leak dye tracing
- USB Charging: Rechargeable battery, single-slot charger and USB cable included; charge from a laptop, power bank, car adapter or wall outlet so any USB source works; indicator shows red charging and green when full, with four to five hours to full
- Aluminium Alloy Body: CNC-machined with a knurled non-slip grip, removable pocket clip and wrist lanyard; compact handheld size for a jacket pocket, glovebox or tool bag; avoid aiming the beam at eyes or skin and let the head cool before handling

## 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ This is a powerful flashlight!
*by  on Reviewed in the United States November 19, 2019*

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

### ⭐⭐⭐⭐⭐ High quality and high power, a good UV light.
*by  on Reviewed in the United States January 23, 2020*

This UV flashlight is very powerful. Using the 635nm range and ambient light filter it is almost invisible but you can see the results of the beam as it touches materials that react to UV light. For most indoor uses the lower power setting is probably best as the high setting can really make reactive materials almost too bright to look at. For that reason, do not shine this light into the eyes of people or animals as permanent damage can happen quickly and those affected won't feel it or notice it until sometime later.DO NOT let children play with this, it isn't a toy.The battery supplied is a 4200 mah type which is hard to find although you can use other batteries. It seems Alonefire doesn't sell batteries on Amazon which is too bad as the supplied battery really holds a good charge and last a long time.An improvement would be to include a magnetic end cap and perhaps allow the selection of the light with a few different quantities of extra batteries.The light will get quite warm on the high setting but then it isnt supposed to used as a flashlight, turn it off when going place to place unless you are tracking an animal.

### ⭐⭐⭐⭐⭐ Way better than expected! Lights up scorpions like beacons!
*by  on Reviewed in the United States June 26, 2020*

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.
