DARKDAWN UV 395nm Light Flashlights USB Rechargeable Ultraviolet LED Blacklight Mini Wood’s Lamp Portable Blacklight for cat Urine Detection Dry Stains, Uranium Glass, Leak Detection, D15 395 nm

I have a professional UV A and UV B light source. Sometimes people ask to borrow it, and I get a little nervous because of the cost. But I saw this product, very reasonably priced, and thought why not? Can't go wrong. I was pleasantly surprised. The UV B performance was 80% of my expensive light. There is a little bit more remaining visible light, which means it probably has some UV A also, but it sure isn't bad, and would not interfere with most tasks. For rock hunters, ID checkers, looking for pet stains, examining skins conditions or just plain having fun, you really cannot beat this light.Couple of things. After 15 minutes of operation, the lens on this UV source is hot. I measured 160 degrees F. The body of the unit stayed at a comfy 100 degrees F. But if using this close to skin, be a little cautious. After one hour of operation, the UV B output was noticeably reduced, but still very usable. The lens temp has dropped to a 100 F.I am at a loss to explain how they can sell this product as inexpensively as they do. Built-in battery, nice aluminum case, carry handle, cute little gift box, quality instructions. Most companies couldn't ship me a paper clip for the amount of money these things costs. I bought another already.Perhaps I can offer this analogy between this UV B light and my expensive model. Consider a digital voltmeter. Entry level meters go from $15 to $250. At the low end, you've got Harbor Freight. At the high end, you have Fluke. Both meters will get most jobs done. For the weekend hobbyist, a cheap meter is mostly fine. But you won't find those on assembly lines or in the tool boxes of professionals. You certainly won't find the cheap UV B light sources on a manufacturing assembly line curing UV adhesives or doing calibrations. I bet your dermatologist is using a much higher quality light too. This UV source ran hot and the output varied considerably over the course of an hour. I charged it up and did it again. It works as advertised.Buy all means - buy one of these!! I bought two already, and I'm going to get some more as stocking stuffers!

I've had this light for approximately 1 year and waited before doing a review. It lights up the lume on my watches stupid fast. 365 shorter wavelength is best for watch lume material and that is what this light is, 365.Charges easily, hold a charge and just works. I like that it has an adjustable hood to make the beam narrow or wide. I've dropped it, left it for month or two without charging, and whenever I go to turn it on .......it works.Not sure what else you need this light to do? It checks all of the boxes regarding Price/comfortable size/bright 365 UV light, charges easily, and turns on every time I've reached for it.

First off, this light is quite a bit smaller (and therefore lighter and more portable) compared to the more expensive competitors. It performs better, too—being on a wave-length with less visible light, which means it is more useful and effective compared to lights with lower wavelengths. It is cheaper than those other lights, too.So far I have found it to be durable, though I also have not used it in any rigorous settings. But the threads on the back that cover the USB (for charging) are nice and thick, which means they should last—and the body of the flashlight is metal, meaning dropping it won’t do more than scuffing the case.It took me a while to find the light I wanted, since I originally bought it to search for Uranium Glass. This was the one I settled on after literally months of searching and researching to find the best light. For heavier use (think whole-house animal urine spotting) to lighter use (looking at the pretty fluorescent colors woven into my passport) I am happy with my decision—and you probably will be, too.TL:DR: Small, Powerful, and has the best commercially-available wavelength light you can find. Will do whatever you need a UV light to do.

I thought it came with the power cord since it's in the photo. That's the only reason I gave 4 stars .

Rechargeable and works great.

This is the BEST little UV light EVER! Especially for the price! I use to check out the UV glow of different rocks/crystals! It fits easy in your pocket so you can take it anywhere and everywhere! The battery life last a long time! Would recommend! 10 out of 10!!

Handy for hunting uv glass.

Even at full charge the light is very weak and barely produces a glow from objects. However, overall it’s a well made case and I like the telescoping feature of the light. I also like that it is USB charged.

Muy prácticas de usar cómoda

Charges up for the use of my reflective crystals, and not too expensive as my crystals were/are.

アニサキスを見つける為に購入。よく見えます。
