I could see UV light also causing plastics to oxidize and become brittle much faster, because they might not be made for that kind of exposure. So using UV light might mean having to replace a lot of plastic things too.

MojoMcJojo ,

Exactly, yes! Pretty much everything when left out in direct sunlight eventually fades or breaks down. There's a reason why UV light kills germs, it damages what is touches.

stoly ,

Because it is very dangerous and people will absolutely let their toddler play next to the lamp. This is why it's basically only used in places like hospitals where access can be controlled.

In the US maybe, elsewhere it's common and accessible. Here in China it's commonplace in home water filters and air purifiers for instance. I can also buy endless UV-C LED strips and do with it whatever I please.

UV light kills almost all viruses because it's ionizing EM radiation. So it also fucks humans up, xd. I mean just stay on sunlight naked for a day. Your body will be so happy. All the mutations from ionizing radiation would be great.

But yeah we life in a society where ppl is scared of Radiofrequency EM waves (non-ionizing), "dangerous cell phone towers, wifi dangerous". That same people recomends staying long periods of time with direct sunlight contact without protection (yeah we need protection because sunlight spectrum has UV and higher freq ionizing radiation).

Sunlight healthy/radio waves dangerous, that is the most stupid statement ever.

Sunlight is beneficial in small dosis because of how we syntetise vitamins (as little as i know). But remeber if you are scared of microwaves, remeber that sunlight has much more higher freq(higher energy) waves.

~~Because that is specifically UV-C and it's harmful to humans too. ~~

for example: https://wwd.com/eye/parties/hypebeast-party-uv-lights-injuries-11036559/

Correction: the article is about even smaller wavelength UV which is not as harmful to humans, my bad.

Rubanski ,

In Macau, they have little trash garages which are flooded with UV at night

AngryCommieKender ,

We installed one in the kitchen cabinet trash and recycling "drawer bins," as well as behind the stove and fridge. It smells of ozone, but there are no bugs or trash smells

onlyhalfminotaur ,

You're generating ozone in your house. You might be okay if you have a good furnace filter?

AngryCommieKender ,

It's not enough to cause health issues, just enough that you'll smell it in the kitchen, but only if no cooking has been done recently

kemsat ,

That’s how you get UV resistant strains of all kinds of microbes

SeabassDan ,

Bleach kills AIDS, doesn't mean you can inject it into your bloodstream and be okay.

sunbeam60 ,

Supposing you brought the light into the body?! Are you going to test it?

SeabassDan ,

They say the eyes are the windows to the soul, it would have to go in through there.

L0rdMathias ,

Imagine writing this headline in a universe where daylight exists rofl.

stoly ,

It's not as if every part of your house has exposure to direct sunlight. They aren't made for use in houses, though. Think more like hospital rooms or classrooms on a cycle when nobody is around.

deranger ,

There are UV light robots at my hospital that drive into rooms and blast it with high power UVB for 15 minutes or so to help disinfect.

Grass ,

The bulbs don't last very long last time I looked into this for home use

Oof, ultraviolet light. This makes me flashback to April 2020, shortly after the U.S. shutdown for the Coronavirus pandemic.

If you have 1:57 minutes of free time, watch this video of former President Donald Trump addressing the nation on the response to the novel coronavirus.

Warning: If you experience second-hand embarassment, try not to watch Dr. Birx in the background squirm in her seat as she sits through the idiot rambling of the orange man. Immediately after this press conference, corporations and media companies pushed out critical warnings to Americans to not drink or inject disinfectants like bleach.

"I would like [Dr. Birx] to speak to the medical doctors. to see if there is any way that you can apply light and heat to cure [covid-19]? You know? If you could? And maybe you can, maybe you can't? Again, I say maybe you can, maybe you can't?"

"I'm not a doctor, but I'm like a person who has a good..."

Gestures vaguely at his head

"... you know what." ~ Former President Donald Trump

shalafi ,

This video always has the beginning chopped off and misses the KEY thing about the whole fiasco. It was even dumber than you think.

Trump is walking to the podium and stops to examine a CDC infographic on an easel. An infographic about ways to sterilize surfaces.

All the bullshit Trump is spewing came from 5-seconds of reading that poster.

AI_toothbrush ,

If it kills all the viruses it also kills you lol

devfuuu ,

Good news everyone!

    You know, his mom had multiple holes you could use instead.

    Dadifer ,

    Aaaaaayyyy, you got me

    learningduck ,

    Yeah UV light alone is safe, but by the end of the article it mentioned that far-UV light also triggers a chemical reaction that creates ozone, which is dangerous. It needs a good ventilator system to make it safer.

    I've been using both a dedicated Ozone generator in unoccupied rooms and a UV sanitizing light built into the HVAC system. Seems to be improving allergies.

    FiskFisk33 ,

    UV-A is quite safe, UV-B are the harmful wavelengths that cause the harmful effects of sunlight, UV-C is much worse.
    The light that kills viruses, UV-C quickly damages your eyes quite severely, and also burns your skin and can cause skin cancer far, far faster than UV-B.

    https://en.wikipedia.org/wiki/Ultraviolet#Harmful%20effects

    UVC, the kind that kills pathogens harms the skin and eyes and creates ozone. The article talks about using “Upper Room UV” which is just lights posted a safe distance away from humans above them which makes it considerably less effective at killing pathogens at the human level and also now theres a whole area of space where you cant go without risking harm from UVC like being on a ladder or some other platform.

    UV also degrades lots of materials a lot faster

    Edit: I meant Upper Room UV bot Far UV

    Dadifer ,

    Far UV refers to the wavelength, not distance from humans.

    Nindelofocho ,

    You’re correct. I meant to say Upper Room UV, I edited it

    Womble ,

    but it kills viruses!

    laurelraven ,

    That's exactly what I thought it would be

    iAvicenna ,
    @iAvicenna@lemmy.world avatar

    can it kill Tardigrades though?

    Dadifer ,

    I'm pretty sure nothing can kill tardigrades.

    frezik ,

    This thread might be the worst example of "I didn't read the article, but I'll comment anyway" that I've seen.

    Tristaniopsis ,

    Yeah but ducks shouldn’t do that!!!!

    (I didn’t even read the headline)

    Did anyone actually read the article? The only guy whose question wasn't already answered by the article was the one about yellowed plastics, lol.
