Alonefire SV18 - Rechargeable 12W UV Flashlight For Stain Detection & Resin Curing With Battery & Charging Indicator - Perfect For Scorpion & Pet Urine Detection Review

I really like this one. I bought a competitive brand one at the same time for around the same price and this is the one I’ll be keeping. It’s bright, hasn’t died on me yet. My only concern was the long time it took to charge, if it was due to a slow charger in the device to keep the battery from charging too fast then I’d understand why it took most of a day to charge.I only have one fluorescent rock but no idea what it is lol

I really like that I can charge it instead of having to buy batteries, however, it does not hold a charge for more than a few minutes.

This light exceeded my expectations by far. I can see clearly during the day , will help you inspect your hotel rooms , spot counterfeit bills , rock hunting , crime investigating, you can see alot of things on a wall or floor that you cannot with the naked eye, as well as fingerprints , it does it all, 10/10 I highly recommend this product, you want find any like it for the price and quality.

I bought this black light to find the horn worms on my tomatoes. I had no problem putting the battery in as one reviewer described. maybe he got a defective one).I didn’t want to buy the beast because the battery’s have been recalled (or not sold anymore. because no "protection” circuitry so they can catch fire. Probably when shorted out. but it was unclear).If you like the beam, it probably depends what you use it for. The beam is a somewhat dim wide beam, with a bright spot in the middle. I’m

It arrived with a dead battery so I immediately went to plug it in and the usb cover came off. The second bad sign was that the charge indicator didn't work at all so I left it plugged in overnight to charge. It worked great once and after it died I plugged it in again and when I came back to it, it didn't work. Had it worked I would have kept it and just dealt with the charger not working as described and given it 3.5 stars, deducting for it being a bit heavy (understandably so, given the…

Got it to hunt for sodalite and it worked for the first hunt. Plugged it in now and it won't charge. Followed the instructions and removed the film. Still nothing. Be prepared for the purchase of another battery.

It works well, and the price was good. Found some glow rocks (yooper lights) with it. Came with a battery which is nice. Only bummer is the flashlight doesn’t throw light very far. wish it was a tad more powerful and threw light far enough to prevent stooping.

Bought this not knowing how it performed because there was no reviews. So I'd like to say that it works very well.I like the features of USB charging without having to remove the battery. Also shows it's status by the color of the power switch both in charging and in use, Includes a UG5 lens Filter which improves the effectiveness of showing fluorescence of LW specimens. It's rated @ 12 watts which is nice. I like this UVA hand held and I would recommend it.

So far this UV light has delivered the goods. Feels weighted and solid. Use it to cure UV glue for tying flies. Powerful light zaps & cures clue quickly. Charges quickly but also seems to last for a good duration. Happy with purchase.

The body of the light is much too short for the included battery, so getting the threads started was a pain. I also had to torque the cap and barrel very tight to get electrical contact through the body. The negative terminal of the battery is now caved in, the positive terminal is bent, and the positive terminal spring in the flashlight is bent.I put in an 18650 to try the light out. It puts out a lot of UV light! The spill light is a reasonable width, but the spot is too intense for most of…

While the actual cold power is only 7 of the 12 Watts claimed, the light works well. Overrating of power and lumens, (which I didn't measure) is pretty typical for these sorts of imported devices. With a very narrow beam, a zoom would certainly be a nice feature. As others have observed, the center area is dimmer than the rest.The surprising news is that the battery actually exceeds its marked capacity at a measured 4.45 Ah. Sliding the battery into the housing is like pushing a cylinder into…

This little cheap light is better than one could imagine. I use it mostly for looking for rocks, but a tour to the bathroom with this thing will make you cringe. If you think you cleaned it well, time to rethink.

This blacklight is extremely well built, performs very well, and does not hit your wallet nearly as much as more expensive options with similar specs.Pros:Can illuminate things you wouldn't have imaginedIs excessively bright in most artificially lit environments, and holds its own in some outdoor settings with the right lighting conditions.Has an amazing heat sinkCons:Can illuminate things you wouldn't have imaginedFilter can get smudged easily, may be a good idea to invest in a glass screen…

I bought a used one that was defective, where when charging, the button does not light up to indicate charging or full charge. But it does work, when charged up and unplugged, the button will flash red when it is on.The light is not a circle of light, it is a halo, leaving the center unlit. I don't know if it runs at full power because it is not as bright as how I've seen the others say it is. The manual says the light says it will automatically power down to 50% after 3 minutes as to not…

Recieved two of these flashlights and both batteries were bad. Only worked when plugged into charger. Seemed to work fine, but I was hoping on a working battery

I bought some of that adhesive that can fix any broken whatever simply by using some kind of superglue and shining a UV light on it. The adhesive kit I bought came with its own miniature UV flashlignt. Or what they wished was a UV flashlight. Didn't work. So I bought this UV flashlight, which is a professional strength true UV spectrum emitter.Yep, works like gangbusters. FYI: You should also shop revain for UV protection goggles. I did. They're cheap, like $12 a pair. Use both.
