UV 365nm 395nm Blacklight Flashlight for UV Glue Curing,Rocks & Minerals Hunting,Pet Stain Detector,Scorpion Finder, Dry Stain, Portable,Zoomable Handheld Ultraviolet Flashlight Black Light

I bought this so I can harden that green paste stuff you put on motherboards to seal off connections you don't want to come together and make contact. This light definitely works. What I like about it is that I can use one of my old use 18650 cheap lithium-ion cells to power it and I don't have to worry about the batteries since I can just recharge this cell. It also feels sturdy and the case is made out of aluminum. It does have some weight to it also. It's fairly easy to use and you don't really need to read the manual to understand how to use it because it's really common sense. It comes with a plastic cover for the 18650 battery to guard it from grounding out on the flashlight case, and also a shirt or belt clip. For the price, it's a good small UV light.

Very much recommended for crazy rock collectors

I don't have experience with blacklights in terms of using several different brands but I have used various ones over the years. This one is pretty nice.Simple on/off pushbutton at the end, adjustable from wide beam to tight spot, sturdy aluminum body, Uses AAA or 18650 battery (s).I have rechargeable 18650 batteries and I prefer them.The 3 push button switches on bright, next dim, next off and different wavelengths really do show different things.I don't know if the price is high or cheap, But I like how it works. I might buy a couple more for my kids living out of state.

Works as it should

Does what it’s supposed to do. Good product at a reasonable price.

Works great, easy to switch between wavelengths, focus, etc.

was looking to see Calcite and Willemite fluoresce under short-wave ultraviolet light but this didn't do the trick.

Works great, found a bunch of cat pee residue from previous owners in new home so I know where to work out the stench. Definitely like having the two diodes. I know some people complain about the lack of a battery but I have several flashlights that use 18650s and not having to purchase a new battery is a big perk. Saves me money and I know I'll get the power output I expect. Reminding myself to throw on some glasses next time because my eyes are fatigued. This thing is the real deal. Only downside is now I'm definitely not going to hear the end about my own pee splatter from the lady...
