UV Blacklight Flashlight - 365nm and 395nm Black Light for UV Glue Curing, Urine Stain Detection, Anti-counterfeiting, and More - Compact Handheld Ultraviolet Torch Wood's Lamp

Works as expected. High quality product. We use it for experimenting with UV sensors .

Working great after a month of rough treatment. I dig being able to switch between UV wavelengths just for fun, but it is also very practical for when you need to switch up. This is not the best UV light I have, but it isn't made to be and having both waves makes it my new pocket light. Also my other light cost about five times more(also worth it though😄).🟪🟦

The mostly visible violet LED at 395nm makes fluorescent objects glow noticeably brighter than the less visible 365nm LED. Too bad that at 395nm, its violet color is obvious and not truly “black” light. The 365nm emitter apparently contains components that fluoresce, because it also puts out an obvious amount of visible light, though greenish-white rather than violet.Good brightness for the size. I just wish its output was truly invisible UV light only.

Nice size, works well to see areas that need to be cleaned in the kitchen, bathroom, or pet spots.

This light is extremely helpful in finding dried dog pee and other pet residue in your carpet. One of those tools that I am very glad I purchased

The instructions for the batteries are misleading. They identify + and - end of the battery and then say “ the + end near the flashlight head and the - near the flashlight tail”. That implies all three batteries face they same way. No no noIf you put all three facing the head of the flashlight it doesn’t work.All flashlights put the negative end on the springy end because the base is flat. One spring is in a different location in the battery casing than the other two so the battery faces the opposite direction. Flat end on the spring ! Then it works just fine.One part of the instructions shows the correct end to insert the battery housing with the pointed end inserted first even though there is a spring inside which likely has to do with the adjustability of the beam. The flat side faces out as shown in the small illustration.Also the semi clear tube to slide over the battery housing doesn’t fit. Perhaps it is for a different model, a mini size perhaps but it is not big enough to slide onto the battery housing. It fits well into the body of the flashlight. BUT The picture in the instructions show the plastic tubing on the battery housing before it is inserted.These three battery small flashlights over the years always have one battery that corrodes and perhaps that is why the plastic tubing was included. Useless for whatever it is intended for. since it doesn’t fit. The outer circumference does fit into the body of the flashlight but the inner circumference is too thick making it too small to slide onto the battery housing. Not even a snug fit… too small

This is a perfect light for my job. I clean bathrooms in the morning so it's nice to use it to make sure I get everything. And I've found blood/urine in places I couldn't even see. This is a really nice black light and UV light (if that's what the blue one is). Great size to fit right in your pocket and the magnifying lense works really nice too.
