DARKBEAM UV 365nm Flashlight Blacklight Rechargeable USB, Wood's lamp Handheld Ultraviolet Black Light LED Portable, Pet Urine Detector, Resin Curing, Anti-Counterfeit, Fluorescent Detection

Works great of fluorescent crystals. Long lasting battery.

I bought 2 different flashlights. This one and a 51 LED model. I prefer this one because it’s rechargeable, compact/easier to carry, and it’s more affordable. I use this for scorpion watch while walking my dog or looking around my yard. I like that you can adjust the beam. It has a far reach and the charge lasts a long time. There isn’t “that much of a difference” in the light strength between the two. While the 51 LED model is only slightly brighter, it’s bulky and eats through batteries like it’s an all you can at buffet! I returned that one. I’ve had this flashlight for a year and it’s still going strong. It’s easy to use and fits my needs. It’s saved my dog and I from scorpion attacks and also saved me money by not buying batteries every week. Money well spent! Here’s a photo of one of the many scorpions I’ve seen.

Absolutely great flashlight! With 365 nm wavelength, it amazingly highlights any urine stains on the carpet, which can later be addressed with some urine-dissolving spray. It is bright enough and very solid built, no moving parts and very expensive high quality look. Solid 10 out of 10.

UPDATE: The device actually did start charging after almost an hour and a half on the charger. it took many more hours to be fully charged. After it was charged it light did work as expected, updating my review from 1 to 4 stars due to inaccurate info on the site and the box. I just got this light, and the battery would not charge at all, there is no red or green light indicator whatsoever. Even when plugging in the charger, there no light that comes on. When you loosen the battery cap, the light will come on under usb power and be green. At that point the UV light can be used but only while plugged into the wall outlet. It does not gain any charge and only works under USB power. I always read reviews before buying items and thought this would be a good purchase, but now I realize how many other reviews state issues with the charging port on receipt. I will be returning this item.

Works very good for curing windshield repair resin

Works good for a/c dye leak test

Great UV blacklight. Use it to detect fluorescent glass at thrift stores. Small and rechargeable so it is convenient to bring in my pocket or bag while shopping. Had to charge upon purchasing but it comes with the cord and has worked well ever since. This is not necessarily for people who only want uranium glass:Uranium glass fluoresces always at 395 nm, this light is 365 nm so it detects uranium glass as well as other fluorescent glasses (manganese, selenium, cadmium, etc). Have also used it to detect pet urine on fabrics. Overall very effective: photo shown is a vintage vaseline/uranium glass cigarette lighter illuminated with this flashlight
