I'm curious, what purposes does a UV flashlight serve? Is it just helpful for looking for scorpions (which is a legitimate concern here in Arizona)? Or are there other reasons to buy a flashlight like this?

If someone knowledgeable would like to reply, I'd really appreciate it!

Around me in Florida, fossil and shell hunting is popular and some types of shells give of some cool and interesting glow under UV light. Also, I think you can find old nasty pet pee stains. That said, given the fairly limited uses, there are a few options sub $10 for a regular battery operated version.

Check about splashes after you (or your pet) pees.

Thanks for the prompt reply and the feedback. Much appreciated!

By the way, what part of Florida are you in? I'm originally from Arizona and have lived here for most of my life, but I did live in the Tampa/St. Pete/Clearwater/Palm Harbor area for about 5 years and I really liked it. The humidity was awful, but there were lots of nice people and I really liked my job (I dealt poker at a horse track, Tampa Bay Downs) and I still often think about the place and the nice people and how much fun it was living there.

Do you like living in Florida? And do you ever see scorpions there? Or any monster alligators or scary snakes?

Auto A/C leaks if a UV dye is added when recharged.

Holding out for the $14.99 price Anker ran back in Feb.

380nm is OK but most UV users prefer 365nm

I got this last month for the same price from Amazon but sales tax was added.
Can't remember, does Newegg charge tax?

I have researched everything about the UV emitters and could over explain it if needed, but this is the gist of it.

1. 365nm is the UV you want for detecting stains or UV reactive materials such as certain rocks.
2. The LG emitter is a lot stronger than the nichia emitters in the UV spectrum.
3. Lack of a black filter lens means you will have LESS usable UV light due to the drown out effect from the purple emitter light. This is why most _GOOD_ uv lights have a black filtered lens.
4. You _MUST_ wear UV eye protection when utilizing these lights if you don't want burns in on your eyes.

I would HIGHLY suggest if you're getting a UV light for detection of leaks or staining, then get a CONVOY S2+ LG UV with black lens filter.

TL;dr - this is crap for detecting stains; get the convoy S2+ LG emitter version with black lens filter.

You can use them to detect scorpions as they will glow brightly when hit with 365nm UV. You can utilize it for detecting leaks in AC units, or car hosing when a dye is introduced. A lot of people who work in HVAC need to utilize them daily. Safety glasses are a must if you don't want to go blind. Your eyes will not properly block the UV and will lead to blindness, vision loss and burns on the eyes. Test the UV blocking glasses by using a uv light to see if any light passes through, if it does pass through, throw them away. They are also good for detecting UV reactive rocks and some people collect them as a hobby.

I own three UV lights. The Convoy S2+ with LG emitter is my favorite, the Convoy C8+ with LG emitter is my second favorite since it's larger but offers much longer distance throw.

For most people, UV lights are _EXTREMELY dangerous. They can reflect easily and hit you right in the eye. Also just being exposed to it long enough will cause irritation of the eye just by seeing the light for prolonged times. Your eyes don't properly adjust and allow too much light in and it will cause massive damage. People will wake up the next day as if they have sun burn on they eyeballs. So again, these are dangerous and not toys.

This version is crap, I would avoid it. This is worse than the 395nm UV light Olight sells and gives away for free all the time in their deals. It's a piece of junk. Neat in design, useless in functionality.

Do not try and attempt to utilize ANY UV light for disinfecting purposes. It will not work, and even when it does, it requires UV-C and tons of hours of exposure time. It's also less effective than 30 seconds with a regular household cleaner.

I bring mine when I got to new hotel rooms to detect when the last time surface areas were thoroughly cleaned so I have a good idea of how much extra cleaning I need to do. I was in Virginia last month and the bathroom looked like a murder scene due to the subpar cleaning. It's also helpful for detecting particles in the air to ensure the filtration systems are working properly and don't need filter replacements done.

Price wise, this is a bad deal also. The Convoy S2+ LG emitter with black lens filter is under $20 shipped from China from most distributors. I paid $15 for mine.

S2 LG LED 1-Mode, Black / SKU: 9651106 would be the correct model from "FastTech" aka China. Vendors from AliExpress will not ship to the US due to a patent troll who has been hitting them with cease letters stating he owns the patent for using black filtered lens on flashlight devices. FastTech will ship to the US but expect really long ship times.

As a flashlight enthusiast, avoid Anker flashlights. They do not make a single quality flashlight for the price. Everything they've done can be beaten for less.

Also helpful for discgolfers playing glow golf. They use the UV Light to "charge" the glow discs before they throw them.

And UVC is very harmful. If you can see the light, your eyes are damaged.

Scientists are developing Far UVC light sources in a very specific, narrow band of frequencies that is safe for humans to use while it kills viruses and bacteria.

It's very promising. I just don't know why it's taken so long.

Supposedly, the light source for far UVC is expensive metal but, in 2020,they should be able to synthetically reproduce that light using other sources.
