1408 365nm UV懐中電灯ライト 強力な3つのLEDブラックライト ペットの尿検出 偽造金 翡翠 Yooperlite 懐中電灯 (バッテリーは含まれていません)

While I can't confirm the wavelength of the light output, it certainly is somewhere in the ultraviolet range. I was a little worried when I first turned it on as it seemed to be putting out a lot of "white" light. After doing some testing by shining it onto various surfaces, I'm convinced that the light output is primarily in the UV range. It is VERY bright and will highlight all sorts of things that fluoresce, even in a semi-well-lit room. I have one of the small UV lights that claims to be useful for finding pet urine that has 9 LEDs. Using that, the room needs to be almost completely dark in order to even get a hint that something is showing up. With this light (it has 3 LEDs) you will see things you never wanted to know about. I also like the fact that you can use either a 18650 or 26650 Li-Ion battery in this light. It comes with a plastic sleeve to adapt it for a 18650 battery. My primary purpose for buying this was not for scorpion hunting, but I suspect it would work extremely well for that. It definitely works well for finding residue from pet accidents, etc. on carpet. Edit: Today (March 31, 2017) I received an optical filter that blocks nearly all visible light but passes ultraviolet light. I tested the filter and it indeed blocks visible light. Then I shined this UV flashlight through the filter. There was a phenomenal amount of UV light that came through it. All the usual things that fluoresce under UV light lit up like crazy. I still can't confirm the wavelength of light it emits but it puts out a lot of light in the UV range. Edit: I had this flashlight in my pocket and it got turned on by accident. It apparently overheated at least one of the LEDs. That was probably due to it being on for quite a while before the battery finally drained and also being inside a pocket probably allowed more heat to build up than normal. In any case, I bought a new 365NM Lamp Holder Pill to replace the damaged one. I don't know if the total output of the damaged one was that much less than it was new but the new light is considerably brighter.

DOES NOT WORK for urine! I have a puppy and of course he pees everywhere on hardwood floors. I clean up the puddles, but wanted this UV flashlight to find the residue. NOPE, does not find any traces of where the pee puddle were.

Excellent seller, fast shipping, quality product! Thank you!

It's hard to find a UV 365nm flashlight with substantial output, suitable for outdoor use. UV 390nm/395nm flashlights (such 51-LED and 100-LED potato-mashers) can be useful for what they do, but they don't really fill the role of 365nm illumination. This one does, and puts out a broader beam for a greater distance than other available flashlights. That makes a big difference when exploring woods or gardens for low-brightness fluorescence (not everything of interest is Day-Glo bright) in plants, lichens, or fungal growth, or spiders! - great for entertainment or scientific study. Performed noticeably better on a good quality high-drain 26650 than on a lower quality 18650. Get a good quality cell from Amazon or your local "vape" shop. Down a half star for poor build quality: mine arrived nonfunctional (I had to solder the front contact spring back in place), and the cooling fins have sharper edges than any other flashlight I have handled.

This uses the correct wavelength of UV to spot animal urine on carpet. I also use it to super charge my glow in the dark 3D prints. It makes them shine bright in the dark.
