What electronic accessory item emits blue light at one end of it?

Could you post a photo?
Are there any markings on it?

Many Bluetooth accessories, such as wireless earpieces for cell phones, have a blue LED.

Electronic cigarette?

Sonic screwdriver?

Laser pointer???

A US currency checker? Does a line drawn with a yellow highlighter light up when exposed to it?

Thanks all but I only heard of it, @hearkat
But @rooeytoo I don’t think so from the description it is more like the amount that is emited by a simple $1.00 pen light, but much duller.
@Seek_Kolinahr I don’t think so, I tried to google image it onic screwdriver, there is nothing.
@DeanV I have never seen one of those.
@LuckyGuy I don’t know, I’ll suggest they try it.

@flo If it is a UV-B or UV-A source they will be able to look for all kinds of interesting things. That will be a fun toy.

@LuckyGuy Is there a term you can think of so I can search it in google image or Google Video?

:-b the sonic screwdriver is the tool used by The Doctor.

@Seek_Kolinahr so it is a fictional item, I didn’t have my sense of humor hat on.

Sorry, it’s hard turn off the nerd switch. Maybe if I had a sonic screwdriver…

@Seek_Kolinahr where would the world be without nerds?

Additional info I rememebered: “the other end of it looks like the end of an RH cable (for VCRs) or what it plugs into.”

Can you take a picture of it?

Is there a patent number anywhere?
If it is an unknown UV source, you should not be mucking around with it without eye protection! Even a short exposure to UV-C will start to do damage to your eyes. It will feel like you have sand in your eyes. Even regular glasses will help protect you.

@DeanV I haven’t seen it, I only heard it being described. I don’t know the person.
@LuckyGuy I don’t know if there is any kind of number on it, but you’re joking around.

If it is UV-C I am not joking! There are handheld devices that produce it. Scary stuff.

@LuckyGuy I just looked on youtube, and there is a guy selling a UV-C hand sanitizer wand If you want to prove it works he says _ “just move it over the thing you wat to sanitize“_ omg!

Incredible. UV-C is used to sterilize water, and the air in certain air handlers. But in those applications the radiation is contained. There should be no leaks. You would never want UV-C on your hands, eyes or any DNA based life form you did not want to kill.

I’m guessing the guy is selling UV-B which is about 1/10 as lethal as UV-C. Even UV-B.is bad without protection.

@LuckyGuy The guy on you tube is selling a nothing item whatever he’s calling it. So sad so many suckers out there.
