DARKBEAM UV 365nm and 395nm Flashlight Light Wood's Lamp Blacklight Ultraviolet LED Portable Mini Handheld Torch Detector for Dog Urine Pet Stains Anti-counterfeiting Identification Resin Curing

This is a great little UV light that is very portable and works well. Its size necessarily means it isn't as bright as larger such lights I own, but it makes up for that by being small enough to slip into a pocket or purse. The light it shines is focusable which offsets the brightness issue. Focussing it into a tight beam intensifies the UV effect. Another big plus is the ease with which one can recharge it. Everything is built-in.We live in an area that has small brown bark scorpions which on rare occasions can find their way into our house. A little-known fact: scorpions fluoresce to a bright green under UV light making them far easier to spot (Credit: Photo by Barb Backes).

I like the ability to change between narrow, focused beam and wide beam. But the wide beam isn't really strong enough to detect much. So I wind up scanning with a mid-range beam size, then using the narrow focus to hone in on things.Works well for pet fluid stains and also for tomato worms. And, wow, tomato plant leaves look REALLY cool under UV light!

Overall I am happy with the product it does what it says it does.But for sure could use a bandpass UV filter, I am going to see if I can find a after market one it put inside to only the UV passes.I can confirm since it is small and low powered that for some things to show you really have to get close to the subject in question.Not great for long distance but fine for most uses.Do not get this expecting it to be as good as one of the higher powered $70+ dollar larger units.Also it does run on a single AA, it does ship with a battery but I would HIGHLY recommend getting some AA lithiums.

I'm sitting here in my dark room, shining this little thing when I realize that I should post a review so other cat owners see this. Lately, my tabby has been peeing in places he shouldn't, and not only did this blacklight find older stains (with this thing I found out that I had been cleaning the spot above the pee stain — not the actual pee), but it also found a fresh pee stain (seriously might have to take my little guy to the vet — or just replace the floor). Cheap, but effective. A must-have for cat owners. I promise this review is not fake!!! This thing is so good at finding weird stains — not just cat pee, but other stuff that'll leave you scratching your head at how many things are also florescent. Again, cannot recommend this blacklight enough!

I would like a powerful and a longer last battery. Of course the price and size, but sure you guys can

Could be brighter and have a strap though.

Not powerful. Battery don’t last long.But it can at least show you what fluoresces in a wink “on site” as it were. The darker the better of course.

These compact UV lights have most of the features of a larger tactical light including the much appreciated zoom spot to flood light shaping feature but are super small and boast an unexpectedly very bright UV light. I don't think I would want a UV light to be any brighter than this, it would be dangerous. This light is so powerful someone could probably tan under it. LOL. Anyways, its superbly built. I have nothing bad to say about it although having a switchable mode other than on and off such as a lower-power setting or a flashing mode to help highlight things that are only illuminated by the light would be welcome additions.UPDATE 01/06/2018): Had some time to really evaluate this light and put it through its paces and I stand by the original rating, but there are some notes that need adding here. If I had a legitimate complaint for this product and its usefulness it would be one of the two following items which I consider minor but others might not like:1. SIZE: That the lights may be just too darn small for people with larger hands perhaps or people with crippled arthritic hands this might not be good. Due to their overall black color in combination with that small size (<4" long by <1" wide) despite the red end switch and small gold UV light warning sticker which only covers one side, are easily lost if you don't consistently clip them to something or store them in something larger or they fall out of your hand by accident and you don't have them turned on. That makes them also more easily stolen by people with swift sticky fingers because they are so concealable, but since many consider smaller size and less weight a positive or even a major selling-point rather than a hazard, I'm not taking off any stars for that minor issue but just be aware of that potential to lose track of these lights in a crowd if you don't keep them secured when they are off and easily pilfered or lost if dropped because they can blend in well depending how they come to rest and with what colors of what materials around them. Also, these are more suited for people with small to medium size hands without any medical issues. People with arthritis or nerve damage to any extend may find that small size impossible to hold onto and favor purchasing a much larger more standard sized light thats more easy to grip and stay gripped in their hand with less effort or focus on holding it a particular way.2. PIN-SPOT VIDEO GAME CHARACTER SURPRISE: If the color consistency or illumination evenness of the light matters at its pin-point spotlight extreme zoom in setting, then you might not like this light so much because at that zoom point, you can clearly make out an exact blown-up reproduction of the shape of the LED chip used by the light with clearly defined squarish dark edges and inner lines.that looks like a character out of a video game or a strange battery gas-gauge indicator. No points off for this ether because this is a common downfall of the zoom focusing methods it seems of all the recent super high powered LED chip based flashlights. But who to blame, the chip maker or the flashlight maker for this? Probably since it's more difficult for the flashlight makers to address such an item than the chip-makers, this may be more of a function of the failure of the manufacturers of the LED chip to include any kind of built-on diffusion lens integrated onto the output side of the LED light chips. Something that should be looked into, but I can't fault the flashlight maker for because they honestly reproduce the light that is given to them at this zoom where the obscuring of this shape at wider zoom levels happens as a function of how optical zoom for this kind of light is obtained with maintaining a very even consistency of illumination across the image which will force a blaring of the input to the zoom at all but the 1:1 passthrough pin-spot setting. Some people may find this fascinating (I do) rather than annoying anyways.

Fácil de usar y dura mucho la pila, es resistente

La descripción del producto dice que tienen dos led, uno para 365nm y otro para 395. medí las longitudes de onda con un espectrofotómetro y ninguno de los leds es de 365nm. El producto o su descripción es falsaThe description mentions 2 LEDs one for 365nm and the second for 395nm. when I didn't get the expected results I measured the waveleghts with a spectrometer and non of the LED is for 365nm.

Item received in order, amazon fail to update reception.

Unfortunately doesnt work on boulder opal. Works on lots of other things though. Good Quality.
