Why did I buy it?Mostly just for fun: I was in a hotel room and I thought it would be fun to check how clean the room actually was.Does it work?The flashlight is very sturdy and it doesn't feel cheap like other flashlights you can find on Amazon. It can't really be considered a pocket flashlight (it's just slightly smaller than a regular flashlight) and it needs 3AA batteries (not included) to operate.At the beginning I was a bit skeptic about the effectiveness of this product as a stain detector, since I used it for 5 minutes and I wasn't able to identify any stain. But this was probably due to my apartment having been recently cleaned since, when using the flashing to check a pillow often use by the dog of a friend, I was able to detect a urine stain (see attached picture).The product really works and the light beam is bright and wide enough. The only minor issue is that the on/off button feels a bit flimsy but I haven't had any issue with it yet.Pros:- Sturdy flashlight- It works- Wide and bright light beamCons:- The on/off button feels a bit flimsyBottom line:I had a lot of fun using the flashlight to find stains in my apartment and I think it would be more fun to use it in a hotel room and ask for an upgrade if I find suspicious stains. I would avoid buying cheaper flashlights: you would spend less, but the product wouldn't last long.

5.0 out of 5 stars Great for Scorpion "Hunting"!
Reviewed in the United States on February 8, 2016

These flashlights work awesome and I use them EVERY night. I purchased several of these to keep in various places in/around the house (various rooms/closets/cabinets/garage - anywhere that is dark). My family moved to Arizona recently and our new home and yard have been infested with scorpions. Since scorpions glow under the UV light, I wanted a flashlight to scout my home/yard in an effort to rid my place of the dangerous pests. After looking at several local AZ retailers (both small & large chain stores) and seeing the outrageous prices they were charging for similar UV flashlights specifically advertised / being sold for scorpion detection, I decided to look online and am so glad to have found these inexpensive, yet quality, UV flashlights through this seller. For my purpose, I wanted a flashlight that would cover a lot of ground - literally! The coverage span of this flashlight exceeds my expectations. The LED's will light up the walls/ground in my yard/house, making the scorpions easy targets for me to spot even from 20+ ft away. These flashlights are a nice comfortable size to hold for extended durations. My husband agrees with this assessment & just told me to order more to give out as gifts to local AZ friends/family so they can be better equipped to deal with the scorpions too.

3.0 out of 5 stars Mostly solid construction and performance
Reviewed in the United States on September 5, 2015

Good performance for the price, I found. Sturdy construction and I like the button action. The battery housing was the biggest issue I had with this product. During assembly one of the contacts for the battery terminals fell out of the rickety housing and it took a minute or two to figure out how to reinsert it. I'm comfortable with simple circuits and tinkering so I could make it work. If you are shy about fiddling with something take care when inserting the batteries. As far as usage goes, if you can turn off the lights it will make your search much easier.

It seemed to detect anything I tested. Including the area I suspected were my cat urinated comes up a white spot. I could see also the sprayed on the wall :/ I now know That I have to tear up the carpeting! It arrived quickly was also a plus. The only thing I did not like was there was ABSOLUTELY no instructions on how to put in the batteries, and I had to go find a video on how to do it. Put in instructions.
Pro: Great sturdy lots of LED. will last
Cons: Little big for travel.

could be brighter and a bit more concentrated but it is a really really well constructed flashlight. very firm and sturdy very comfertable too. for 51 led's its of very good size and i love that it takes aa instead of aaa. this flashlight picks up semen and piss stains well like a standard black light. its bright when at a distance or looking dead on when used as a normal flashlight its not as vibrant or spread but it does the trick under the light certain colors and paints and yes appear bright red or orange. urine and semen or other bodily fluids of a clear to yellow nature appear bright yellow or white glow. skin flakes and stuff can be picked up. dried up blood stains can be seen but you couldn't tell what it is if you went in using this light unsuspected. i thought the blood stains would be picked up significantly but they looked like dark spots on a pillow case so. lastly in case anyone's wondering where and how i seen such substances i work crime scenes. i want to mention that finger prints didn't come up to well in fact little to nothing at all even a fresh one. basically anything you can do with a standard party style black light you can do with this only handheld and battery operated. all in all super cool gadget im loving it. the price could be lowered a tad. but in the long run i think its sturdiness and battery life will make up for it.

5.0 out of 5 stars This OxyLED blacklight is a fantastic price for this quality of build and powerful 51-LED (395 nm) output!
Reviewed in Canada on June 20, 2016
Verified Purchase
This is an excellent UV flashlight. You get 51 LEDs as opposed to much less powerful models that are similarly priced. This light was way more cost effective (and powerful) than the ones I found locally at local pet supply stores. It would probably be a good idea to also purchase special UV glasses to wear when using this flashlight, not only to protect the eyes but to enhance the fluorescing of items revealed by the UV light.

The light itself is very solidly built and the on-off switch has a good tactile feel to it. The handle is metal and robust.

This light is 395 nm but does put out some visible light (another good reason to use it with special tinted forensic-style UV glasses). Note that different wavelengths of UV are suitable for different purposes, so you should read up on this subject depending on what you are trying to achieve (pet stain versus human, use of luminol in forensics, building inspection, UV ink on documents, etc.). I'd suggest buying this light AND one of the shorter wavelengths (such as 365 nm) to better cover the gamut of applications if you like to be prepared for all situations.

This is definitely a quality flashlight that I'm glad to add to my toolbox. Don't let children play with it, keep it locked, since UV light is not good for your eyes and this flashlight is powerful. Considering this kind of light is best used in a dark room, and your pupils open up more in darkness (thus letting in more UV light), I can't stress the importance of treating this flashlight not as a toy but as a serious work tool; respect your eyes! The visible light you see from this flashlight is NOT the UV, so be aware that there is much more output in the invisible-to-the-eye spectrum (but which is used to make items fluoresce so that they then become visible).

I'm glad the light uses AA instead of AAA batteries, since the AA batteries will have more capacity. When changing the batteries, pay attention to the arrow on the battery holder to know which way to insert the holder back into the flashlight. The arrow points towards the lamp head.
If you put the battery holder in backwards, your light won't work.

I haven't tested the water resistance but it does seem built solidly enough to withstand some dampness or indirect splashes at the very least. There is a protective rubber gasket at the ends of the threads (where you screw in the battery cover). The push-button switch is covered by a firm rubber "ball" that looks like it seals up flush against the body of the flashlight to keep water out of the switch.

The OxyLED is great when used in conjuction with UV ink pens, anti-thief powders, fluorescent leak detection dyes, etc. At this price and build quality, there's no excuse not to have one in your toolbox.

This is an amazing black light. Perfect size and nice wide lens. We purchased this flashlight to check for cat urine on floors and/or rugs. We may not have read the description correctly as our cat had an accident and did pee on an area rug. The light did not show markings on the rug, But worked super well on everything else that we put tested the flashlight. I would highly recommend this item except for urine markings on rugs. Thank you

Just what I was looking for. I was a little hesitant to get the really small UV flashlights, so I thought this one would be better. It was perfect. Enough light that you don't need to be on the ground searching, but not too big and expensive. Perfect if you have pets or need to really check on the cleanliness of a room. Easy to use, quality construction, great product. I would definitely buy this again and have recommended it to my friends.

If you've got pets, get this flashlight!

I bought two of these blacklight flashlights, one for a friend. They arrived on time, but I was disappointed to find that one had such poorly attached battery connectors that they came apart while I was inserting the batteries. After a lot of jiggling & a number of failures, I was able to get the connectors back in place. The second flashlight had an annoying rattle in the LED head which I was able to stop by adding a bit of padding. Both flashlights worked satisfactorily once these minor irritations had been taken care of so I would still recommend them.
