Olight i5UV EOS Mono-Output EDC UV Light Detector High Efficiency 365 nm UV LED, AA Battery and SKYBEN Battery Case Included

Compact, power efficient, does what I need it to do in a compact package.

This light works okay, but is not as bright as my i3uv was (lost the head on that one so replaced it with this one)

This little UV light is great, just make sure you actually want to see what it will show you.I was going to take some pictures of things around the house but once I got to the bathroom, I changed my mind. What looks clean can actually be quite dirty.Of course there are other uses for this light. Certain bugs and scorpions light up with this. It can be good to see if your pet had an accident. It can be used to set uv glue. I'm sure there are more, but it can also just be fun.It is small and takes an easy to find AA battery. I haven't used a whole battery yet so I can't attest to battery life. Overall I find it to be a nice little addition to my lights.I'll add some pictures of various things in the next few weeks.

Waring UV protective eye wear is a must! I never looked at the LED at all, but just the reflected illumination from curtains, pillows, bathroom marble, etc. burned my eyes. I even had on UV protective clear prescription glasses so I can't imagine the shape I'd be in without them. It feels a little like what people describe as "welder's flash".The flashlight is very high quality and extremely bright, but you won't realize just how bright until it hits a fluorescent object. Like I said, be careful!If Olight is reading this, I would highly suggest mandating UV protective eye wear in the user manual.Update:I went to my eye doctor on 1/13 and they confirmed with fluorescence dye that my corneas were indeed UV burned. UV protective eyeware is a must. Please don't take the danger lightly.

My wife uses it for finding antique Uranium glass in Goodwill stores (the glass fluoresces under certain wavelengths of UV).

I love this little UV light. One thing to note, there is some variance to the splash patterns on different lights so no two look quite the same! The fit and finish is real nice, from the aluminum body with a swirl cut in it for grip and the double pocket clip.Why a UV light? What is it good for?UV light can be used to check for counterfeit bills.Got a pet? Pet's sometimes have accidents, but you can't quite pin point where all of it is? UV light can make those stains show up in the dark.Scorpions? UV light makes them glow in the dark. No seriously, if you live in an area with scorpions and you want to find these suckers, a UV light will make them glow in the dark.

Plenty bright when it makes things flouresce. 365nm wavelength is deeper into uv, so it's not as visible as 395nm.This light is awesome. Eats batteries like mad though.

The 365 nm wavelength is more in the UV spectrum than visible so fluorescence stands out more since you're shining less visible light around the objects. Bleeds just enough into the visible spectrum that you know it's on, which is important for safety. Don't shine it on exposed skin.
