DARKBEAM UV Flashlight Black Light LED 395 NM, Ultraviolet Flashlights, Rechargeable USB-C Woods Lamp, Water Resistant Focusable, for Leak Detection and Curing UV ResinClimatePartner certified

Got the flashlight relatively quick in terms of shipping. Out of the box came packaged pretty neatly with a charging cable.Charged fully in about 2 and 1/2 to 3 hours and then it was perfect to use as nightfall was about to arrive. He used it in the backyard and it has a very strong beam in flood mode, and when you focus it has very good specific quality. It's pretty lightweight, and it is pretty small to keep in a pocket or in a small toolbox. Look forward to using this to look for UV dye leaks in AC systems at our shop

You better make sure your bathroom's clean before you turn this little bugger on it will scare you it shows you everything that you haven't cleaned a must buy for sanitary people also great for rocks at illuminate under black light you can adjust the focus to wide or narrow beam very bright light

This is a clever and interesting tool for identifying contamination, After having read about how it might be useful, I ordered it on a whim. Only two days and I have found numerous uses for this investigative tool. (Interestingly enough, it turns out that my use of OxiClean tends to mask what I am looking for, because garments washed in Oxiclean tend to light use like the surface of the sun!)

I’m guessing that if you’re looking at products like this, you’ve seen some sort of commercial or video in which a person in a dark room points out germs or fluids highlighted by a UV light. I was one of those people let me tell you you think you buy a UV light because you wanna see all kinds of fluids and things that are not visible with the plain eye in your bedroom and bathroom, etc. but then you get this thing and you are seeing all kinds of fluids and germs and things in your bathroom and bedrooms and it’s actually a bit of a nightmare now …

Right out of the box it needed to get charged. Which is understandable and usually standard practice with new products. I charged overnight and next day it still blinked red indicating it needed to be charged. The uv light was dim until it flickered and turned off. I recharged overnight and same deal the next day. I shouldve believed the one star reviews that had the same issue. Gonna ask for replacement and give a chance. Will update review if the new item works as its supposed to. I guess its quality control issue. And you get what you pay for sometimes when you roll the dice and order china made or other foreign country made products.Update: They sent me a replacement and this one actually worked. It was shipped in like a day or 2 and this one does as advertised so im happy now. No complaints.

Finally found the perfect one. Small, powerful with an adjustable beam and rechargeable. I have tried a few and this one is the one for me.

If you wanna see how dirty your kitchen REALLY is, a must have. All kinds of other uses. Catching night crawlers, finding luminescent stones and jerseys, or just to have a cool ass black light in your pocket. Built very well. For the cost of a pack of smokes where my brother lives!!!! NY by the way. Lol. Buy one. Just good entertainment to check on your sex life too. Wink wink.

First of all, IF this was advertised as a 395 NM UV A flashlight I would have given it five stars. It is a good value if it was marketed as a 395 NM UV A light source. If marketed honestly - this is an awesome 5 star product.But marketing this as a 365 NM UV B light source is a travesty. A UV B 365 NM light source produces zero visible light. This produces plenty of UV A, but it comes with so much visible light it almost looks like a standard LED flashlight with low batteries. There is nothing discreet about using this light source. It is obvious, you are holding the source.If you need a true 365 NM UV B light source, this is not what you want. Go get the UvBeast 365 NM light sources. They cost more, but are true UV B. There is no visible light emanating from these.But, if you need UV A, and can tolerate a fair amount of light bleeding over from the visible spectrum, then this is a VERY NICE product. It is a good value, it is well-built. The spot to wide angle zoom works well. I really like that. It allows surveying a wide area and then quickly bringing more illumination on things of interest. The picture shows my everyday carry LED flashlight next to the the item being reviewed. No trick photography, that is how much visible light this Darkbeam flashlight produces. This is totally unacceptable for a product advertised as UV B.Again, this is a 5 star UV A light source. But as advertised, at 365 NM, it fails. Even the instructions get it wrong. They describe the 365 NM UV B as "a bluish light". The human eye will not detect UV B. However, parts of the human eye will fluoresce under UV B, but this is not the light emanating from the UV B light source. The instructions go on to say "UV-395" is a violet light. No, violet is a visible color, their UV A LEDs produce some violet and this light source does not filter it out.
