Do UV Lights actually clean and disinfect?

[Azza ☠]

Does anyone know about those smart lights with a cleaning function?

The smart light can change colours right and it turns purple with a UVC light to "clean" the room from pathogens, bacteria and viruses.

You would have areas in the room which might be under shade, so it can't reach those spots unless you have multiple UVC lights around. Still won't reach under the bed, etc.

Then how long would you need to run it, in which time it should be a dark room and you need to avoid looking at the light yourself or have it prolonged on your skin. So leave the room at night?

Could it kill off bugs, perhaps mosquitoes, or would they remain unaffected?

Would it really prevent Covid or you getting a cold/flu virus, when it's just one room of the entire house and you would head on outside too, etc?

I'm curious to know if that's a gimmick or not?

UV light is known to kill certain bacterias (viruses and protozoa). However it won't kill off all bad bacteria and shouldn't be exclusively used to disinfect waters. I have UV lights on my smart toilets but wouldn't rely on it for drinking water as some bacteria has a wall/coat that is not penetrable by UV lights.

I just bought a smart device that let's me flush my toilet using an app on my phone.
The only downside is I can't be at work and flush the toilet as the device and my phone has to be on the same network.

I love technology and smart devices, specially those that can speed up and automate repetitive tasks.

Perhaps I should look into getting a Japanese toilet?

you're a germ and if it was 100% effective it would simply remove your hands from existence.

I'm actually afraid if I was in the same room as it, it would wipe me out or at least my skin and eyes.

hey now, piezoelectric sterilization is harmless and the sword would go thermonuclear before it had a containment breach.

even if you hit it with an a/m bomb most of the energy would be shunted back into the dm spectrum owing to the 'geodesic prefernce' induced by the matrix.

the wave patterns in my rug are due to almost a century without proper maintenance. or any at all really. except wiping the rust off, which is when this started so. clearly just normal behavior.

it also got stored next to scrolls and stuff so again, harmless.

I didn't want my ♥♥♥♥♥♥ wall molybednium to breach containment down the road, you know? the entire point was designing a nuclear waste container that retained function rather than being literal wasted space. and time.




unlike uvb, which will automatically trigger melanoma in vulnerable populations by creating the 'first impact' that sets off their melanin cell cancer cascade. I heard mj's melanoma was caused by people who wouldn't stop pushing UV on him, for example.

They can cause skin cancer.

I'm just glad I don't live in California. Where they have a label with Proposition 65. I would find out that almost everything causes cancer!

...but yes I would avoid going in the room that's "cleaning" with UVC light. It's why I was wondering how long it would take? Multiple hours at least to do a good job?

the prop 65 bill originally didn't recognize the lead in peas as a carcinogen, but republican state lawmakers changed the wording of the bill during a revision, and the federal democrats put pressure on local state democrats to go along with it in the sake of bipartisan ship and de-escalation.

thanks obama.

the relevant wavelengths are blocked by glass, among other things.

so you need to make sure you are using the right type of lighting element or it wont work.
unfortunately, those are made of things like sapphire iirc and can get a bit expensive.

as such, do a bit of research before buying or you wont be seeing any results.

what you're describing is likely a gimick...

while the proper spectrum of UV light can kill germs, it can also kill parts of you... it's not a thing to play with... and it's not a "multispectrum magic wand" sort of device.

ya, isn't it crazy how laser tech is jumping forward lately?

first time I saw a video of one of those rust lasers they got these days I was like "yup... this is the future."

I fail to see how this is related tho?

so you're trying to adapt an industrial laser to kill germs? or....?

this is becoming more and more ridiculous the more I try to make sense of it.
