DARKBEAM 365nm UV Flashlight Black Light, Mini but Powerful Blacklight USB- C Rechargeable, Focusable Woods Lamp Water Resistant, Detector for Pet Urine, AC Leak Detection, Curing Resin

I didn't expect this little light to do so well! I have a box I cast out of resin and couldn't fit it comfortably under my little light stand to cure the resin to put the pieces together. I got this and thought it wasn't a very bright light, I wondered if it could do any good. Sturdy little flashlight, though. It worked! Within a minute, the resin was cured enough that I didn't have to hold it together! It has more power than I thought. Charges quick and keeps the charge for a long time. Perfect for my purposes!

This is going to make finding those pesky AC leaks easier to find. The flashlight is compact but very powerful. The rechargeable feature is a plus.

This is an excellent UV flashlight that is USB C chargeable and has the 365nm wavelength that works very well at highlighting stains, be it pet stains or otherwise "potty" spots that the normal human eye cannot see. The flashlight is rather small but it does work exceedingly well with the given wavelength of light. It is a rechargeable via USB-C but I don't see any means to opening this up and replacing the battery within, if so I would give it a full 5 stars. There is a "focus" beam by pullin out and pushing in the front lens, so your can widen or focus the light in on a more narrow spot... Overall this is a well made and great UV flashlight, but I can't seem to open and replace a battery if needed. I hope this will batterh last!

Works well for seeing fluorescein stain. I like the rechargeable feature versus needing to replace the batteries.

Small but has a strong beam. Purchased to detect cat urine. Handy size. Smaller than a pen. Rechargeable so no batteries to replace. Holds a charge many hours too. Not made of plastic so it will last if dropped. The beam is adjustable so wide to thin width. Came packaged well. Good value as well.

Bought these to go look for yooperlite rocks and we just got back from our trip. These lights were worthless, you had to have them inches over the rocks to see anything. We adjusted the focus thing on the end and it didn’t matter. We bought two of these and one of them also has a very different color light than the other one, it looks whiter (as seen in picture). Finally the battery life on these is limited and as we still tried to use them it only got more difficult as the battery life was used. It is also unfortunately too late to return as the window closed before I used them.

This flashlight is a good size, and works well for finding spots around the house. I purchased it to find yooperlites. Other flashlights that we were using worked much better and made yooperlite hunting much easier. Battery life is ok, but our other flashlights last longer. This is a small flashlight, and is easier to store in a pocket etc

Quality feels cheap. These don’t emit nearly as much light as similar led flashlight. Disappointing.
