DARKBEAM UV Flashlight 365nm Woods Lamp USB Rechargeable Portable Blacklight LED Ultraviolet Light Mini, Detector for Pet Urine, Stains, Uranium Glass, Money, Amber 370nm, 2 PackClimatePartner certified

These work great! Good value, size, design, visibility, and use. Durability? We shall see. About the size of my finger, and fits in any pocket. (Although, if anything bumps it, it's coming on.) The switch, should be more recessed to prevent this. The battery only lasts for one hour? That really sucks! Thank God these are rechargeable! (Also has a 180 day warranty!) I only use these for my lumed watches anyway. I need a uv flashlight to see them at night. (Make sure you get the 365nm not 395nm.)Awesome!

Good for looking at Amber. Garnet takes on a life of its' own at this bandwidth. USED WITH CAUTION, is a wonderful way to explore minerals.

I recieved this a few days ago. I tried it out on my collection of glass. It works very well to show uv glass. I was surprised that some of my glass that had never glowed before did with this flashlight. See the picture of the clear glass stopper that turned yellow. Also included picture of a yellow piece of glass to show how bright it glowed with this light.The flashlight is small and should be easy to carry to have handy when antiquing.It charges with a USB cable, not sure about the longevity of charge as I haven't used it for a long period of time yet.One note is the light does get warm, but the body of the light doesn't.I am really happy with this light so far.

I love these lights. Not a ton of bleed from the filter. You can't beat them for the price. I have one I use in the field so I don't care if it gets dirty, and one for the house. Everyone I recommend these lights to really like them.

Quilty of the lights are great. They are true black lights. Should have really paid attention to the brightness of them. Not the products fault but mine. Work best in low light to dark environment. Where a brighter one will not care. Would buy a brighter one if you're using it for dye tracing and ac system.

I bought this to sort thru jewelry donations at my local non-profit. It was my task to sort and price each item and I found it nearly impossible to tell if pearls were real. Real pearls glow brightly under this light. It won't tell me the quality of the pearl, but at least I know if they are real to price them more efficently.

I have bought a few dozen of these to sell with other items in my business. I have never had a complaint or a return. Use one myself.

I am impressed with the product. I use it to cure epoxy and it is extremely effective.
