## Description

GearLight UV Flashlight S50-365 nm Mini Blacklight Ultraviolet Pen Flashlights for ID Check, Leak AC Detection, Resin Curing - Pet Urine, Scorpion, Stain Handheld Detector - (Pocket Light) - 2 Pack - desertcart.com

Review: Pretty good 👍 - Dropped it down a flight of concrete stairs and still worked great. Pretty decently bright. But not the brightest.
Review: Just what I needed and at a great price - Here is the short of it: These things are a great value and well worth their price. Actually they are a bargain for what you get. I use my flashlights a lot due to aging eyes, a lot of work that needs good illumination and two dogs that I have to take out every night. I have been through a lot of flashlights, large and small and have learned what I like and what I don't. This light I love. What I like: Very reasonable price. In fact this light is worth much more than its humble price. Nice size and features. The simple push button on the end is easy to use and works well. The size of the light is very convenient and fits easily in a pocket out of the way. Brightness and color: This thing works much better than I could ever expect. I am just very impressed with its clean white beam and the brightness. I can walk my dog at night with just this little powerhouse. Build: It seems very well made for the price. Again, I have a lot of lights but none of the lower priced lights come close to this thing. I love it. Its just what I needed, sized right to carry in a pocket, nice and bright, built very well, simple and best of all it uses normal AAA batteries not some odd ball special or expensive battery like AAAA's or CR123's.. I use the Panasonic rechargeable and save even more money. Yes, I would buy it again without a thought. Fact is I think I will get some more and give them out at Christmas as a stocking stuffer.

**Q: Can this detect fingerprints?**
A: Not certain, but you can use a UV light to detect fingerprints, but on some surfaces, you need additional items such as powders, etc. to make them stand out. I would say it depends upon the type of surface, but this item does not claim specifically to be able to detect fingerprints from what I read.
