After a recent event in Hong Kong where people attending a fashion event were exposed to dangerous levels of short wave ultra violet energy, I decided to make a video on the different types of UV tubes available on eBay. That includes the dangerous UV-C type that can cause eye and skin damage.
One thing I missed in the video was the importance of UV in the making of vitamin D in your body. A reasonable amount of exposure to sunlight is actually desirable.

It's been pointed out that the main mercury hazard to hatters was the use of mercuric nitrate in a process called carroting.

If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:-

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.

people go on and on about how welders don't get enough sun, pasty skin, low vitamin D, etc… but as soon as they spend a little time around UVC its all, "AHH MY EYES!"
Shout out to the nft bro's getting butned and blinded in 2023 time's really a circle ain't it lol
Big Clive: "black people are optimised for use in the sun". Totally well meaning comment that does sound a but unfortunate 😂😂
I work on a manky production environment, and ive learned how to run and maintain a whole bunch of machines. Thos has landed me a much higer paying role in Germany of all places ☺️
The condition is called Photokeratitis
It seems this happened yet again at the Bored Ape Yacht Club's "ApeFest": Attendees are reporting waking up with "searing eye pain, vision loss, burned skin"
i expect you’re about to get a bump in views and shares on this, considering that hypebeast have just held another event in Hong Kong using UV-C as decorative lighting recently
This apparently just happened again. People at ApeFest, a NFT cryptobro party got their eyes seared and skin burnt in Hong Kong.
The event was open to holders of Bored Ape NFT's. Attendees are reporting they are unable to see, woke up with vision loss and everything.
That's going to be a fun insurance claim.
This just happened again at a Bored Ape event in Hong Kong recently too.
They use bluelamps to prevent intravenous drug use makes it hard to fnd a vein
my dad has psoriasis, so we have uv-b tubes in the basement in a lamp structure. he can only expose the front and back of his body for 30 seconds, and has to wear protective goggles. any longer and he’ll burn. he’s never gotten a melanoma or anything, and he does have to go to a dermatologist to get checked. not every psoriasis patient can tolerate the treatment, but my dad can apparently.
he got new tubes paid for by provincial healthcare a decade ago and those are still going strong, but before they approved the payment for the replacements, he would have to be in there for a while since they had become so much less effective.
Yesterday saw a video how UV destroy bacteria eventully bscteria exploded under uv.
You have 995k subscribers! So close to a mil! Congrats!
Yeah, UVC can cause skin cancer VERY fast stating from the fact that you said your hand smells like burnt flesh after just a few seconds holding your hand in front of the transparent tube!
so uvc or uvb do they flouresc anything? how come uva floureses but not uvb or uvc?
What about Mercury amalgam fillings?
the uv A & B we used in accelerated weathering chambers. t12 4’ lamps. great job explaining
the difference with the different types. have a great day.
The first tube, the black light blue wood's glass tube displays with a pink glow that I can see easily enough whenever UV-C is being emitted. Yes, I can see that, think it's some phosphorescence thing going on. I do see UV-B and UB-A as well as just violet shades beyond what others see from a prism's violet. Natural lenses are long gone, replaced by plastic implants after cataract surgery. Apparently, around 1% of patients report being able to see some amount of UV after surgical removal of their natural lens (the natural lens blocking UV entirely).
So, to me, that concert image already would set me on alert, as that pink is the color I detect with UV-C. Although, UV-A will send me packing as well, as it's quite brilliant to me and also fluoresces something in my eye, washing out my vision painfully.
Now, I'd still happily own a UV-C lamp – for ozone production and sanitation reasons, with a very well vented sealed cabinet being made just for its employment. Ozone and I don't get along well at all, irritating as hell to my throat.
UV-A and B, a case of why not, for their features of detection of specific substances by fluorescence and tanning purposes. Not too concerned about burning, as being of Sicilian stock, I tend to tan dark. My father tanning literally as dark as a wooden telephone pole in summer. I tan deep enough to confuse Indians and Arabs.
For giggles, I looked up vacuum UV sources. Had the devil's own time finding one I could purchase if I wished to without going through the "contact us" link, all came with vacuum chamber connections, which is actually a good thing. Can't think of any use I could put an actual ionizing source to though. Maybe if I was designing spacecraft, otherwise, nope.
