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

High quality and high power, a good UV light.
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!
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.

Impressive!
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.

Works great for cat urine (and many other things)
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.

Very good longwave flashlight
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.

Small But Mighty
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

Please Read
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 packing peanuts or air pillows!!!! Honestly I got lucky there was no damage to the actual product or product box. With such a quality UV light itself, the included battery I would NOT trust nor the charger it comes with. Both are unknown branding and the battery looks like it came from a flea market. Get some high quality Sony or LG batteries and a Efest charger on amazon or at local vape shop. I use Sony VTC5 batteries and a Efest LUC4 charger bay dock. You can’t go wrong with this setup. Light gets hot quickly. Be careful!

目には見えない汚れも浮き立たせます
鉱石の判別に使いたくて購入しました。 届いたあと試しに家の中を照射してまわりましたが、あまり見たくはなかった現実がたくさん浮き彫りにされました。 しっかりと紫外線が射出されているようで、性能に問題はなさそうです。

Gute Taschenlampe mit der netten UV Zusatzfunktion. Akku hält lange und lädt auch schnell genug. Stabil genug würde ich sagen, nur drei mal bisher runter gefallen alles ganz. Helligkeit wunderbar und der Zoom/Fokus passt auch. Wasserdicht weiß ich noch nicht, da nur im trockenen gebraucht, aber die USB-Abdeckung sitzt top.

Très efficace
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 Search Pas de regrets, rien que pour ça :0)

Linterna UV 365NM
Muy buena linterna UV en general Estoy muy sorprendido con esta linterna de la marca Alonefire (SV003) debido a su longitud de onda (365 NM) y su potencia Contenido: 1 linterna SV003 1 cargador de batería por micro USB 1 cable pequeño de carga USB a Micro USB 1 batería de 2.000 mAh a 3.7 V (Modelo 18650) 1 correa de mano Muy buena linterna, perfecta para su propósito, es de las mejores linternas UV que he usado Características: Marca: Alonefire Modelo: SV003 Origen: CHINA Batería: 2.000 mA Voltaje: 3,7 V Modelo batería: 18650 Luz UV: 365 nm Potencia actual: - 6 W (Con la batería de 2.000 mA) Potencia máxima: 10 W (Con batería de + 3500 mA) Estructura: Aluminio Color: Negro Dimensiones: 120 mm de largo x 22,5 mm de diámetro Peso: 96,5 gramos (Con pila) Indicador de carga: Rojo y verde Producto recomendable, es sin duda la mejor linterna UV que he comprado y la que más información me ha proporcionado, ahora es cuando me doy cuenta de que mis otros modelos apenas hacían nada. * Hay un detalle que no me ha gustado, es que nada más encenderla a los pocos segundos calienta bastante y claramente calor es consumo, pero bueno no es una linterna para darnos luz, solo para detectar ciertas cosas.

Works Well, Good Quality
Bought this as a gift, really lights up glow-in-the-dark filament and can even cure UV resin though I've only tested small quantities. You can feel the heat from the beam! Quality aluminum case, battery lasts a while.
