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

It's actually a bit chunkier than I was expecting compared with some, but a good fit to the hand. A true black light, it emits at 365 nm rather than the ones with longer UV that emit at 395 nm, but the longer UV ones also have a fair amount of incident white light, so if you are interested in photography, it's probably a better bet because you don't get the same amount of white light contamination that can saturate the photo. The stone, for those who are interested, is syenite, a type of granite sold as yooperlite (also available on Amazon) and contains inclusions of sodalite which fluoresces (in this case) orange. I like the fact you can recharge and use it at the same time, gives you more flexibility - others need a separate recharger for the lithium battery itself.

This is a lot cheaper than others but its actually great and what I was looking for. I thought for a cheap,one wouldn't be good but so much better than I was expecting. Its great for minerals which is why I bought it. Great little uv torch.

Received item on time. Unfortunately, it was an Open box unit covered with fingerprints and some tiny scratches all around. Strap was connected to the handle as well. There was no sticker / seal attached to the box that confirms if item was never used. Therefore, if I'm wrong and that is brand new unit then I'm worried about quality and life of the product...Not sure which option is worse here. Again, second hand items shall not be sold as brand new.

This light outputs pure UV light with little of the visible spectrum. I have compared this with cheep UV light on cash note and the difference is clear

Fast charge, last a long time top.

This is the best UV torch I have ever had.For form factor is perfect. It's very comfortable to hold.It comes with a weird rechargeable battery in the box. I love this, it means that I can change the battery when it eventually stops being effective; it's not sealed inside.I love that I can charge the battery whilst it's in the torch (no need to use a special charging cable).The torch is extremely effective!⭐ It makes bodily fluids glow!⭐ You could use this to investigate a crime scene!It's actually quite scary how good it is.

In terms of pros, the torch is premium feeling with a weightiness to it, but the pros end there.I initially bought this with the intention of using it for detecting pet urine - however it seems incapable of doing so, as I have smelled dry areas that are definitely soiled that the light didn’t catch.I wouldn’t recommend it for this reason.

Light isn't bright on it at all, i left it on charge all night and it only lasted for 1 hour of intermittent use so I sent it back not worth it at all

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.

Lampan fungerar bra, klarar lite avstånd också.

Verwende die Lampe zur Lecksuche an Klimaanlagen, die ist so Hell das man nicht mal mehr die Brille braucht um das Leck zu finden

très efficace ! au top !

Me ha sorprendido mucho la calidad de construcción. Su funcionamiento es perfecto. A tener en cuento que cuando hay mucha luz apenas se ve como ilumina, pero si que ciertos elementos o colores realzan igualmente.
