LIGHTFE UV Flashlight 365nm Blacklight UV302D with LG LED Source, Black Filter Lens, Max.3000mW Power for UV Cure, Glow Rocks, Pet Urine Detection, AC Leak Detection

I bought this light for inspection purposes. I needed a 365nm light to inspect for dust in semiconductor mini-environments. It worked great for this purpose -- highlighting dust much better than cheaper 395nm UV lights. But I was very surprised at how well it highlighted scorpions. I took it outside at night and found 13 scorpions on the first night and 7 more the second night -- and I didn't even know I had scorpions in my yard (Phoenix, AZ)! Scorpions light up like beacons under this bright light. I had no problems with the end cap as mentioned in one review. I suppose if you're turning the light on and off every minute or so for an 8-hour shift then maybe adjusting the brightness every time you turn it on might get annoying. But I just turned it on, adjusted to max brightness, and left it that way -- and I had no problems with it. Practically every LED light works this way. It should go without saying that this light is useless in bright daylight (or any kind of bright condition). It works best in complete darkness. It "kind of" works in dim light conditions.

I bought this to replace a common 395 nm multiple LED blacklight I had been using, and so far like the portability and the power this little flashlight can put out. I have yet to try it in the field, but it seems to have a pretty good range, and brightens well the few fluorescent specimens I have. For comparison, I have provided photos. Photo 3, septarian in ambient indoor lighting. #4, with unfiltered 395 nm UV. #5 & #2 new LightFe 365 nm, high and low settings. (Lights held approximately 10-12 inches away in photos 2-4.) #1, using LightFe in ambient indoor lighting, approx. one meter from specimen (3 ft.) light held approx. 1-1/3 meters (4 ft.) from floor. Field use will tell the tale about battery life and durability, but it feels well built and sturdy. I look forward to spring, when I can get outdoors with this and see what it can reveal!

We purchased this to detect and monitor ringworm in cats we were fostering. Unfortunately, it lights up ringworm like a Christmas Tree. Well, maybe fortunately. The flashlight itself feels strong. It is sturdy and well built. Using it on cats, it got dropped many times. I had no doubts that it could take the impacts and it is still going strong. The battery lasts a long time on a single charge. It has been lent out to other cat parents several times and I don't remember the last time it was charged. The case is durable and convenient. I'd put this above the "tactical" flashlights being advertised.

To start I’m not a professional in need of a UV light. I am a pet owner that was in need of a light that would be able to find urine stains. I did some research and found that 365nm was the optimal wavelength for finding urine stains. Searching through the plethora of UV lights on the market, most being very affordable in cost but not listing the wavelength. After a few refinements I came across this one. Despite being more expensive it offered the wavelength and output wattage. This particularly states 365/395 and 10 watts. Reviews checked out and the quality seemed to be pretty good. Ordered. Upon arrival I was impressed with the build quality compared to a cheaper torch I bought years ago. Vast difference in quality. I found that the black out lense is built into the house so it’s not exactly removable. Not a big deal at all. What surprised me is that I was under the assumption that there was an ability to switch between 365nm and 395nm. It’s an on/off switch and if you slightly depress the button you can cycle between low, medium and high brightness. I was hoping that it was a switch between the two wavelengths. The complaint I have is that the torch is advertised as 10 watts. The instructions that come with the torch indicate optional max power of 5 watts. It was presumed that there would be a 10 watt output at each setting that doesn’t exist since both wavelengths apparently run at the same time? Overall I’m very happy with the purchase and it is beyond adequate for the purpose needed. I have been both astonished and disgusted with fluorescence within the home that this revealed. I would recommend this torch for its cost and quality. Just be mindful of how the specs read. To the manufacturer, I would have liked to see the end cap being purple on this torch like the next model down. It helps distinguish what it’s for.

Bought this UV light on a whim. It seems to be very sturdy and well made. The light is bright and it lights up fluorescent materials very well. The spot is not large but that is normal for a small light. It works very well, especially in a darkened room. One thing I didn't like is that the box had been opened sometime before it was shipped or delivered to me. The tape holding the lid on had been cut and the lid put back on rotated to that the tape on the sides of the lid didn't match the tape on the bottom of the box. I contacted the vendor who responded promptly. They indicated that their products are shipped out by Amazon from some Amazon warehouse; perhaps someone there opened the box. (There seems to be no way to ask Amazon about this.) Regardless, the flashlight seems unused, all the items in the box are accounted for, and the light works.

I have previously bought and tried several products for the purpose of identifying carpet stains, including the (in)famous Peedar, but none of them have performed adequately with our carpet; the stains were always virtually indistinguishable from the fluorescence of the carpet itself and/or the excess visible light spectrum emitted. I came to the conclusion that their inefficiency was due to their emittance of too much visible light spectrum and not enough of the invisible wavelength(s) that can make certain things fluoresce. Out of relative desperation, I again researched several much more expensive alternatives, focusing on products that claimed to emit light in the 365nm range. I eventually settled on this product as what seemed to be a reasonable compromise. It is indeed a compromise: it does perform better than the previous products, including the Peedar, but it is considerably more expensive and it still emits quite a bit of visible light spectrum. Is it really so hard or expensive to engineer a glass filter - or filters plural - with the right doping to block all but a narrow band of light centered on the 365nm wavelength? Even if a single filter is inadequate, two or three combined could surely do the job! This will work for us, but it's not effortless and requires a completely darkened room and much squinting to make out the contrast.

Description is false. Advertised as having an LG led light source when in fact it has a cheaper led from another manufacturer. It appears to be a Seoul Viosys. Not as bright as advertised. Switch was also wonky. Bought a different brand that was less expensive had a better led and lower spec but brighter led output. Does come with a sheath and charger and extra o ring.

It has no marks or scuffs. All parts came with it so no issues there. The problem is it was used. There is supposed to be a paper tab to keep the battery out of circuit until sold to a user. The battery paper tab was in the box which wasn’t packed quite right. This was sold, returned, and then shipped as new. It was almost new but the battery had been left in the flashlight to completely run down dead which is hard on that kind of battery. Amazon should not be sending electronics out with batteries like this in circuit. I bought a Nest fire alarm some years back and same thing - it was used and shipped as new. It had been given a location and was configured by someone else, also with the battery still in circuit and draining. I’m keeping the flashlight since it looks ok but I’m really tired of getting used products from Amazon. I get keeping prices low but I end up holding the bag for a rechargeable battery that was left in circuit and run completely dead and left to sit like that for no telling how long. Unfortunately, the ding on battery life is entirely Amazon’s fault. I have no idea how it would fare under normal use and won’t be able to tell since this is a used device stored improperly.
