ALONEFIRE SV84 365nm UV Flashlight Strong 45W USB C Rechargeable Black Light for Pet Urine Detection, Resin Curing, Scorpion, Fishing, Minerals, Cure Glue with UV Protective Glasses, 4PCS Battery

Comes with the batteries, a lot of people don't want to buy a light without them. This is an important factor when shopping to many. It has USB C charging, so if you live in today's society, you have probably 10-15 different spots to charge it.First off, the UV light is NOT BRIGHT. It's not meant to be. It does however show things you'd never expect to be there. I warn you, if you think your house is clean, this light is going to drive you insane, it shows everything.Built quality is on point. Very hefty feeling body, excellent button placement, charging is easy, and a decent lip over the lens. The ONLY thing I wish they'd have included was a good lens cover. UV is NOT good for eyes, so if you buy this get yourself some sort of cover.The batteries last a decent while, considering the wattage it's pushing. It has two modes which the high mode will change your perspective on clean. We've found some really cool stuff out in the woods at night with this light. I WILL get warm with extended use on high, it's pushing quite a bit of power. If you'd like to see the true measurements on it's abilities I suggest searching up one lumen on google and check out their insanely in depth review.Overall, this is a fantastic light for a decent price tag. If you're wanting to see how dirty things are or go out and explore and find some REALLY cool stuff at night, this is the best bang for buck out there. If you're debating on purchasing this one, I'd highly suggest just pulling the trigger. Alonefire really did a great job on this light.

First off….. do NOT get this if you’re OCD about being clean, or your spaces have to be clean. This up lamp shows things….. you may not want to see. Ancient stains show, dust is amazingly clearly seen, splashes of liquids you thought you scrubbed immaculately clean, this light will show. This UV light is filtered, which means it won’t seem bright until it hits a UV reactive object or substance. DO NOT look into the active emitters, you could cause eye damage, do not play with kitty with this light, do NOT EVER let your children touch this light. From what I see that this light emits is very high UVA energy.Now that all my warnings have been said. This is a pretty solidly built light. Tight and smooth threadings on the body pieces, comfortable to hold and very simple operation. One click from off is high power, one click while on goes into low power, another click turns it off. 4 quad element emitters shine through a filtered lens that allows it to emit just as near or on 365nm wavelength UV. Or in the UVA spectrum. This will not sanitize fully surfaces it shines on, and it’s not intended to do such a thing. However what it will do is illuminate yooperlite stone, white objects, and…….. it does very well, almost too well at showing pet urine stains, dust, and chemicals on surfaces that react to UV, I haven’t thank god had a scorpion near me to see how well they show up, and I don’t want to *shudder* but this would do the trick.The beam can get hot on the skin and the emitter head can get warm during high power operation. But that’s normal. Haven’t had it long enough to gauge charge levels, and how long it can run on a charge. For its price tho, it’s a very good unit. Too good in some cases. Simple, effective, easy to use. A excellent value in my opinion and time will tell on its durability and longevity which I hope is very long. I do wonder who makes the emitters tho.

Extremely bright, everything lights up even what you don't want to see.Great product, great price.The only problem with mine was it didn't work when I got it, it would not charge, the light would flicker then turn off. I found out it was ground issue. ( bult on a Friday at beer o clock i assumed)I tighten the screw on the positive side with a small nail, now it's perfect.So if you get one that doesn't work make sure it's tight on the positive side.I will get another one, and will recommend this product to anyone. Do not shine this light in your bathroom, it shows everything.

This light is very bright and works great. All the reviews about charging are partly correct. It won't charge on google or Apple high power usb c to usb c. It charges fine on usb to usb C low power. Works great.This isn't a light that can be used for long periods (1hr +) it gets warm quick. I used it for 45 min scorpion hunting.It illuminated them from 20 to 30ft. Very bright, you need to be careful with using this light safely.It would get a 5 star if it charged on 20-30w+ usb c to usb c.

Great high power low level black light. Works great for identifying and finding certain types of rocks and gemstones. Much brighter and stronger than previous ones. I’ve bought by other brands. It does get very hot so you can only use it for short periods of time between letting it cool off. It’s very compact and stout slightly heavier than you would think it would be, but it must have a large rechargeable battery in it. Charges with a USB-C cord, which is convenient if this one wears, I would happily buy another.
