TATTU U2S UV Flashlight Rechargeable 365nm Black Light Torch with ZWB2 Filter, Blacklight 10W Ultraviolet LED Lamp with Micro USB Charging Cable

I bought this UV flashlight to cure optical UV adhesive for a microscope prism. It did the job as expected. In addition, the flashlight feels solidly built (it's aluminum with black finish), and easy to charge. The charging USB port has a rubber cover that seals well. It looks like it would be at least water resistant (rain).I had no way to test the actual wattage output of the light so i can't attest to that. I can feel warmth when I shine the light on my skin from 6 inches away.Incidentally, it's kinda fun shining around the house in the dark or outdoors at night, and seeing what stands out. Now when I clean the bathroom, I'll shine the light afterwards to see how bad of a job i did.

I bought this flashlight to do UV-activated free radical polymerization in my lab when our $1000+ UV lamp crapped out. It has worked great for over a year now, I now own two so I always have one charged. If you leave it on for more than 4ish hours it gets really hot and the plastic bits around the lens can melt a little bit, but I wasn't supposed to leave it on that long anyway. I don't know how wide the spectrum is, but it activates very small concentrations of Irgacure 2959 so it is definitely outputting 365nm. Thanks for saving my PhD project. These flashlights have been my most reliable piece of lab equipment.

I bought this because my son has been acting werid and has brought this girl over atleast five times now and has closed his door every time she's over. So when he was at school I did a little investigation and found many stains on his bed sheets and on his wall. I asked him about those stains and he said he didn't know how they got there. I knew that he was lying so I told him if that girl comes over again please clean the sheets and walls.

this little flashlight is powerful and works well but i have to warn you that if you use in your house you may be shocked by all the dust and stains it finds! i would give 5 stars but i am upset that goggles are NOT protective. this was promotion with flashlight. any uv blacking glasses will have that imprinted on glasses. these are just yellow, supposedly as enhancers.

This UV light feels well built and provides a very good amount of light for its size. I still feel it is a little costly but have not seen a better option in this category.

I can’t comment on the longevity as I’ve only had it a few days. But it worked as advertised to find dried places where the cat had peed in the past. It obviously lights up a lot of other stuff (fingerprints on the walls, mysterious old spills on the carpet) so you kind of have to have an idea what you’re looking for.

This flashlight relies on a cut filter to block out other light and then only show the 365nm. However there cut filter barely works. It's probably got just a regular cree type led bulb in there. I've got a real 365nm flashlight and it's a thousand times better then this.. You can't even feel any heat when you put it on your skin like if you pointed to your arm you feel no heat my other one that's the first thing you feel. So if you're trying to give yourself cancer with it it won't work. Is it bright yes but it's bright with all the extra light that you're not looking for when you buy a flashlight like this. Extremely disappointed. Yeah it's not going to work for what I need to work for. I should have known better than to buy this when I saw I had a lens filter on it. Improper 365nm LED does not need a cut filter. Not that this one even works. I'm sending mine back today to get my money back.

Best UV light I've owned. Really like that it's rechargeable. I use it for curing UV glue and leak detecting.
