Nice
Great UV light. Battery included would have been better!
Reviewed in the United States on April 16, 2023 by MR

Ultimate small UV light source!
This light is the best small ultraviolet light source that I have encountered. It's small, extremely powerful at the highest setting and has the ability to be dimmed down to the brightness that suits the task at hand. It goes forever on a good 18650 battery and is extremely well made. It will open a world of hidden things that are only visible in the UV spectrum, like security features on driver's licenses and credit cards. Detect cat or rodent urine stains that are invisible to the naked eye. Lots of other uses like gemology, which is what it was originally designed for. I love mine! ... show more

Battery not included - and it's a specific lithium battery
Flashlight requires a specific Lithium battery, and BATTERY DOES NOT COME WITH FLASHLIGHT !! Now I have to go find this specific battery before I can even see if it works. Very disappointing.

So much more powerful than I expected
Best to find stones in the wild or identify rubies. You can get the batteries here on Amazon.

Mediocre
For a $60 light with no battery, it could be better. It does not illuminate minerals in the way I had hoped. It can illuminate only the gem quality areas on rough stones, but not well. I suppose this is better for seeing impurities/inclusions in cut gems. I am returning mine.

This is the best UV flashlight I've bought
This UV flashlight is the best one I've bought from Amazon. I've bought 3 or 4 and use them not only to identify flourescence in minerals but also to harden UV Epoxy. This UV Flashlight has a super feature of a dimmer making it very useful.

Very sturdy, reliable unit
Built like a tank and should be with me for decades! Well made, strong and comes with a belt loop based carrier. This is a good product. I just wish it offered both long- and short-wave UV options. Then it would be perfect for gemologists!

Works Great!
The knob is a little hard to turn, otherwise good product.
