ALONEFIRE SV003 10W 365nm UV Flashlight Black Light for Pet Urine Detection

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

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.

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.

On a whim I decided to buy this. For $25 not a huge loss if it turned out to be a piece of junk. So far, I don't think that's the case. It uses a standard 18650 Li cell so it will be easy to find replacements if the LED(s) don't burn out first. Using the supplied charger and plugging it into a regular port of an Anker Quick Charge 3 wall wart https://smile.amazon.com/Anker-PowerPort-Charger-Charge-PowerIQ/dp/B01N2HIR9R/ it took probably 5 hours for the battery to charge. The LED in the charger turns from red to green when the battery has been fully charged.I could find no reference showing correct installation polarity for the battery so I installed it like a regular flashlight, namely positive in first. The endpiece containing the on/off switch threaded smoothly into the housing and has an o-ring seal for water resistance. The on/off switch has a good, solid mechanical feel with positive action. It's either on or off. There is no momentary on position. This is a good thing considering the amount of current the light is pulling. The light came on so the polarity was correct and man was it bright! It lit up things all throughout the apartment and easily made things glow in other rooms 20+ feet away. The light's output is filtered so no visible light or fluorescence is emitted.The housing is heavy black anodized aluminum. After running the light for a couple minutes, I could tell that the housing was getting warm. Because of the high current draw, power dissipation from the LED is high and heatsinking is a must. That's where the aluminum housing comes into play. If it weren't aluminum, and say, plastic, it would melt down on you! This unfortunately is the light's weak point. You need to pay attention to how hot it gets. Not so much for being burned, but the lifetime of the LED will be significantly reduced the hotter it gets and the longer it runs hot.While I've only had the light a couple of days and haven't had the need to recharge it yet, it's an impressive device and could be useful for many applications. I might actually buy another to bring into work because we use UV cement to bond optics and this light would be strong enough to do a large area cure instead of needing to use a 1/4" spot lamp all the time.

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 at something that is uv reactive, it will illuminate very bright and with very vivid color. Under UV light sources without the 365nm filter the amount of visible light outshines a lot of the color and contrast. This is the exact opposite. Anything that is not UV reactive will not glow at all, and no visible light to reflect back interfering with the UV reactive material. The battery life is fine. Since it's rechargeable and comes with a charger it's hard to complain about that.

I purchased a blacklight on sale because I wanted to find cat urine (elderly cat... you know what I mean) around my house. The light I purchased was over 385nm and showed me NOTHING. Soooo I purchased this one! AND WOW THIS LIGHT IS AWESOME!! Its probably a little too good. It illuminates EVERYTHING! I took it around my house in the dark just for fun and today I am scrubbing my walls haha

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.

I had one of their older models. It went bad so I ordered another because I felt it was a good color. This new one is whiter. I don't get the same glow from it. I use it for hunting for nice corals at the reef store.

Testé une minute dans le couloir de la maison juste avant de recharger la batterie ( livrée chargée à 80% ). La batterie s'insère par le + en premier si vous vous posez la question ( rien n'est écrit ), comme dans PRESQUE toutes les torches.Si c'est votre première expérience et que vous ne voulez pas savoir si il y a poussière sur les murs ou traces de doigts, n'allumez pas cette lampe ! Vous allez vous faire peur ;o) C'est impressionnant ce que l'on ne voit pas habituellement ( je n'en avais jamais testé à la maison).Utilisation ludique donc cette fois, juste pour voir si ça fonctionnait au déballage, il ne devrait pas y avoir de problème, les watts semblent bien présents car elle chauffe rapidement puis ça se stabilise et la portée est encore efficaces à plusieurs mètres sur certaines fibres par terre ( non on n'avait pas encore passé l'aspirateur). Compte tenu du délai ( 2j ) le tarif est très satisfaisant.A voir au travail en conditions réelles mais au vue des résultats ça semble aller très bien et confirme les impressions d'un autre utilisateur ( pro ) dans un autre commentaire, ce qui m'a décidé aussi pour cet achat.PS : Petit essai rapide pour les pêcheurs, elle recharge votre leurre super vite ! Testé sur une Yamshita Q Live SearchPas de regrets, rien que pour ça :0)
