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.

It fits right in that weird little small pocket in my jeans so that I can easily grab it when looking for certain types of glass at thrift stores, which it lights up brilliantly, by the way! It's a twist to turn on so it's nice that I don't make mysterious clicking noises. I can hide it in under my fingers and activate it one handed so I can be more stealthy. (I don't want everyone in on my glass finding game or asking me a bunch of questions!) It is pretty bright with a fresh battery, but it gets dimmer. It's almost too bright to be stealthy at first. I use rechargeable AAAs with it. It has helped me find a bunch of neat glass pieces and some other substances that I'm not as thrilled to find, but it's nice to know that they're there I suppose.

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.

I purchased the UV302D with the intent on using it for UV photography (not UV fluorescence) with my modified DSLR. It works perfectly for this, sample photo attached. I'm removing 1 star because the product description said it came with UV protective glasses and even though there was a spot in the box for them they were not included with my shipment. The inclusion of a Li-ion battery and extra o-rings is a nice touch. The included charger reminds me of an early 1990's charger with the spring loaded negative terminal, not sure why they went that way as it makes the battery harder to seat because the spring is pretty strong at the end of the length you need for the 18650 battery. It has also been fun shining it around at night to see what's on the walls and floor (the stuffing on my dogs toys fluoresces brightly). Overall I'm very happy with my purchase.

I was looking for a 365 to check glass while I am out and this is perfect! It seems to be high quality but it's new so I can't attest for longevity. I'm very happy with this light.

I never got to see how this flashlight worked as I used the original battery and new ones and the flashlight would never work. And I even got a replacement and that didn’t work! Very disappointed as it was supposed to be a gift. Piece of junk!!

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!

not as powerful as our uv beast flashlights obviously but work great for the convenience of having it or your keychain. will buy more.
