LUMENSHOOTER S3 365nm UV Flashlight with 3 LEDs, Powerful Blacklight Flashlights for Pet Urine Detection, Resin Curing, Rocks, Scorpion

This may be "overkill" for some households if you only have urine problems from time to time: there are less expensive types available on Amazon. On the OTHER hand....this is a very solid and well made rechargeable black light. Structurally it is "heavy duty" with thick well finished metal construction. The large rechargeable battery promises long life, depending on use. Be sure to charge the battery fully with the charging unit before using. It's spring loaded and ensures the battery stays safely and firmly in the charger. FOR OUR household, this is an excellent unit upon first use. We have four dogs who are both inside and outside. Two are rescue dogs: an old male Shih-tzu and old Italian Greyhound. The former, as usual for most males, piddles on multiple areas and furniture feet daily (he is too old to "get fixed" according to the vet). The latter has a bladder problem and he "leaks" droplets daily all around the house. He was in a animal sanctuary for a year or two before we received him. SO......while we clean daily, we found out last night with first use of the light, that we missed a lot. Fortunately we use a spray that breaks down the urine, so the house doesn't smell, but we missed a lot over the past 2 months. We also live in a rural area, so it will be "fun" to see if there are any scorpions around: generally the wild birds like quail seem to keep them out of sight.

IT WORKS. easily detect dried cat urine on hardwoods and carpets. for whatever reason, it doesnt appear to work on Persian rugs. its solid, well made. we initially purchased a cheaper version, less than $10, and it did nothing at all.

This was such a fun purchase! I wowed my college botany students by shining this on a solution of crushed spinach and alcohol to show them how free chlorophyll molecules fluoresce and glow neon red under UV light. And of course, it’s great for finding yooperlights on the beach! Or simply going on a night hike in the woods. I would recommend anyone who’s into nature buy a UV flashlight—there are so many organisms that glow under UV!

I love the rechargeable battery! The light is compact, shines bright and illuminates everything! I made the mistake of shining it around my sink and bathroom and now I'm cleaning everything with extra effort!

I have a collection of minerals from the Franklin mine in New Jersey, which is world renowned for glow-in-the-dark specimens. Some glow wonderfully under this light, but others that I know will glow under other lights will not under this one. I’m assuming that’s because different minerals require different wavelengths to give off photons. The light works great for detecting, old dried cat urine, and gross stains in hotel rooms. While exploring in my garden at night, I found a centipede that lit up like a firefly under this light.

When I was a kid, I learned the joys of rockhounding and scorpion hunting using portable, battery-powered fluorescent black lights. They were the best tool for the job at the time, since the only other options were incandescent flashlights with Wood's glass (UV bandpass filters), which just plain don't work, since incandescent lights produce almost no UV radiation. Fast forward <mumbles> years, and I recently ordered this Lumenshooter S3 flashlight after reading reviews, watching comparison videos, and otherwise researching the best bang-for-the-buck UV torches. Some of the reviews here on Amazon state that it gives off too much visible light. Either the reviewers are able to see UV light better than most, or what they're seeing is fluorescence. Because, let me tell ya, this thing puts out a LOT of light, but almost none of it is visible. If you look directly at it (which I don't recommend doing, at least not without glasses that block UV light), it looks like three very dim purple LEDs. However, you'll also immediately feel the heat on your face from it, which is much more likely the interaction of the UV light with your physiology than actual radiant heat. However, since it's longer-wave UVA, it's not likely to cause any real harm in short bursts. When I point it at ceramic tiles in a pitch-dark room, the tiles themselves stay very dark, almost black, while grout between the tiles and any substances on the surface of the tiles glow very brightly. This means almost all of the light coming from the flashlight is fully in the invisible UV spectrum. Even fluorescent blacklights give off more visible light than this torch. I've been able to see things fluoresce that I never have before, things I didn't even think could. This might be why some folks thing it gives off a lot of visible light. It's strange to see so many things glow so brightly when not even fluorescent black lights have made them light up like that. About the only drawback so far I've seen with this light is that it only takes one 18650 battery, and even though such batteries have decent capacity, you'll still want to keep at least one or two spares on you if you want to venture out for an evening of rock hunting. But, for half the price of the UV Beast flashlight, it's not at all a bad compromise. Get one, and have fun discovering just how gross your bathroom really is. Then, you can feel even more grateful for immune systems.

I did get this for another purpose BUT I’ve been using it on my nails to cure them with the LEad gel and the time is cut in half because the strength is a lot stronger. I gave my other LED lamp to a friend and just use this when needed.

Works as well as I hoped. Finds all sorts is gross stuff in the house. Bright enough to use outside at night.

Works realy well. Very bright.

Powerful blacklight torch shows up stains and particles but is a bit hard on your eye's without the required tinted safety glasses.
