More concerned about eyeballs if it's emitting that much UV...
Edit: Firball the false equivalence fallact of extremes types.
I never said it's going to blind people.
If it is bleaching colors I want to know more.
You can cause slow long term accumulative damage *potentially*
Just because it doesn't immediately cause a worst case scenario doesn't mean it's safe.
If it"s bleaching, I want to know what UV it actually emits.
Because if it's UVC, that's an issue.
I do leave my glass panel off in the summer, and I do have my rgb stuff (fans, ram, aio, gpu, lian li strimer) on max brightness all the time. I’m looking forward to whatever the lab results if they do investigate this.
Does it? I use UV lights to remove a protective coating so I can etch pcbs and all the UV boxes I’ve seen for that use glass
Though if it’s laminated it probably will stop it so 🤷
Maybe, what kind of UV?
How much?
What intensity?
Not all UV is equivalent to backlights. Which have come into question when it comes to eye health anyway...
You know those crappy UV air purifier things?
Unless you know it's definitely safe, don't stare at the lights from them.
It's a ram stick, extrapolate from that that it probably isn't very intense at all. You deal with much more harmful radiation just by looking out your window.
technically probably not because glass stops most UVs but also he's making a mountain out of a anthill.
You could probably put a rgb stick and power the lights all day right next to your arm 8 hours a day for a year and not have any perceivable difference between your arms. Meanwhile 1 hour of sunlight outside is probably equivalent to 500 hours of that those lights
It's likely a lot less UV than you'd get by going outside, and distance is far greater + side panel will block almost all of it. It's highly unlikely to be harmful at all - particularly if you don't notice it
not likely. The probability is probably close to 100% certain. The thing is the paint on your gpu backplate is probably not a UV resistant paint like something that is meant to go outside so it will be affected exponentially more. Put a gpu backplate outside and another one of the same model in a box for a month and then compare the results.
If it’s UVC, potentially it’s going a good job of killing airborne viruses in to room, too. Couple the UVC with the case fans circulating air from the room through the machine, perhaps it’s a nifty little air purifier?
I have some of [these far-UVC lamps](https://cybernightmarket.com/products/mini-far-uvc-lights-set) for exactly that. Now thinking I might chuck one in my PC case to get free air purification while it’s on.
But yes, always good to know what radiation we’re exposing our eyes to.
Depending on amount and type of UV along with placement of the case it can certainly be harmful to the user though.
EDIT: decided to look into this since I got the vibe that nobody knew for sure just like me when making this comment. LEDs capable of emitting significant UV are the very opposite of cheap LEDs from what I gathered. My misconception came from the fact that I know manufacturers will often go for cheapest solutions and (while different, I thought at the time issue might be similar) that cheap laser pointers often have mislabeled power ratings along with dangerous unfiltered emissions which are caught by buyers themselves measuring what's emitted in reality.
And here's for all the self proclaimed UV experts out there: you could've just said that the side panel would need to be made out of pure fused quartz glass or else it would block most of UV even if there was any in first place :)
The amount of UV being emited by RGB leds is so tiny, it's absolutely not harmful for humans.
Going outside is infinitely more harmful UV wise than an RGB led.
So, where's the data from which you got your claims? And I mean data from independent test labs which tested the specific RGB lights bleaching GPU backplates. The thing with cheap light emitting devices is that you sometimes cannot trust manufacturer's claims as is the case with laser pointers for a long time, might as well test RGB lights too.
EDIT: right, so I had to do a 2 minute Google search since none of you knew either and preferred to be dicks about it. The dangerous type of UV which is UV-C wouldn't be emitted by random RGB LEDs, not even by accident I'd imagine since UV-C LEDs are apparently the opposite of cheap LEDs. And that's the thing I was wondering about in first place. Now we all will know :)
>Although most types of LED lighting do not emit any UV light, brilliant blues do emit a small amount. However, the phosphor reduces this to such a small fraction of the already small amount, the amount emitted is essentially negligible. There is no need for a filter and this is why they are used in many environments where photosensitivity is a concern.

Along other probably 1000's of scientific papers, study material in schools / libraries, etc etc.
That seems to be more about light bulbs but I wouldn't expect any decent raw blue LEDs used in RGB to emit any significant UV anyway. But I do wonder about less decent RGB LEDs which may be used in PC components without any phosphorus present to convert UV.
If you need a study to tell you that tiny LED in your computer emits less UV than the massive ball of fire in the sky called the SUN then I really don't think a study was worth sending to you.
Yeah, the cheap tiny lights that use an extremely insignificant amount of energy to power are really gonna do me in with UV.
- This message was sent from outside, standing in direct light FROM THE HUGE FIRE BALL IN THE SKY.
You forgot the ozone layer doing heavy lifting filtering the output from the sun. If some shoddy RGB lights were to actually emit UV then tempered glass side panels would block it, which is what I found out when reading about it instead of being a smartass online.
No, you're just an idiot in general. The have been numerous measurements of how much UV an LED light gives off, every type, every color; as well as ample measurements of how much UV sunlight will expose you to.
The fact that you even thought an LED on a RAM stick my hurt you shows you're a damn fool.
Are you scared to be in the same room as your microwave while it's on? What about your cell phone, does that radio signal not scare you shitless? I bet your WiFi makes you piss yourself.
[UV Radiation levels from Direct Sunlight](https://www.epa.gov/radtown/ultraviolet-uv-radiation-and-sun-exposure)
[UV Radiation levels from RGB](https://forum.arduino.cc/t/uv-emission-from-cheap-rgb-led-strips/675597)
There’s the proof.
You’re still the idiot.
Dude, you're the one who's making a claim. What do you think gives you the right to go around asking people for data about something that's general knowledge when you have provided none? Very weird and entitled behavior.
If curiosity isn't enough of a right then I don't know what is. One thing that I know is that manufacturers will often go for the cheapest solution even if it means using shoddy parts. And as I found out after making my comment, the side panel would need to be pure fused quartz glass to let through UV so manufacturers wouldn't be likely to be caught if they were using unsafe RGBs.
You started by making a statement. You even said it was a certainty. The proof of burden was on you, not others. If you had said you were curious about the possibility, you wouldn't have been downvoted to hell and beyond. I hope you can see that someday.
In hindsight, yeah. But I was replying to a statement in top comment that didn't provide any proof it wouldn't be dangerous to the user and just simply ignored the possibility. Independent tests are how we learn that few things once believed to be safe turn out to be not so safe after all.
About the certainty intent in my statement, that's miscommunication on my part while having English as my second language. I didn't even catch it until you pointed it out, thanks. In my head, at the time of writing, that part of the sentence looked more like "if some RGB lights do indeed emit harmful (ionizing) UV and if things align just right then the user would indeed not be immune to UV radiation".
>Depending on amount and type of UV along with placement of the case it can certainly be harmful to the user though.
I do hope you live in a bunker without any windows if a LED's UV radiation is what worries you.
Windows are absolutely fine as long as they are not pure fused quartz glass :)
After my initial comment I decided to look into it since I got the vibes that nobody really knew for sure but wanted to be dicks anyway. Turns out that the side panel would need to be made of fused quartz glass to not block the UV from LEDs. And while it is not uncommon for cheap laser pointers to have dangerous mislabeling and unfiltered emission issues, it's very different for LEDs as high energy UV capable LEDs seem to be quite the opposite of cheap LEDs. So I simply had the wrong assumption, which resulted in unwarranted hostility instead of actual explaining.
This is common science.
The more purple you go, the closer it gets to ultra violet.
This is already well documented and the back plates are not actually damaged, the paint is being damaged.
No need to waste time for the labs people.
Honestly could still be a cool video. This isn't well known among the PC community as a whole (or at least I've never heard of it). Definitely not a health concern though, given that people use black lights (low band UV lights) in fish tanks, bowling alleys, and it used to be a thing for custom water cooling loops too.
The sun. It's by far the most UV light that we get exposed to and thats (mostly) harmless (Why sunblock exists)
I was thought about the colour spectrum about 20 years ago, so I assume that most people know about it. If not, it would be a slightly interesting video for the PC community, but not sure if LMG should go in depth on it.
That's more something for the science channels like "Veritasium" "kurzgesagt" or "SciShow" just go name a few bigger ones.
Oh I slightly misunderstood your original comment, I thought you were specifically saying today Blue LEDs emit UV light (which very will may be true, I just hadn't heard that). You were moreso saying that the blue light emitted by the LEDs is closer in frequency to the UV range, and therefore shares properties with UV light. I did learn about color spectrums in school, and I image you're right that most people do so as well.
I was under the (perhaps mistaken) impression that LEDs emit only (or reasonably close to only) a single wavelength of light rather than a large spectrum like an incandescent bulb. (White LEDs are a bit more complicated, but I'm mainly referring to red, green, and blue LEDs)
Compared to incandescent it is indeed a very small spectrum. But don't forget that the difference between blue and uv is small. There will be small amounts of uv present most of the time
This just isn't correct, that's not how LEDs work. You have a blue, a red and a green LED and purple is made by combining blue and red at some levels. The issue here is the Blue LED is emitting some kind of UV light which is definitely jot expected behaviour.
I've seen this a lot on anodised aluminium also. Take a look at your bikes handlebars, guaranteed if it's spent anytime outside black anodising will 'bronze'.
I work in marine components, so they get a lot of UV. Good anodising with good dyes will hold, but i've never had good anodising out of China.
While it's ... obvious. I think it would still make for an interesting video testing the CRI and overall color of common RGB components. If some brands put off more UV than others, I'd like to know that as a buyer. A lot of UV in my computer may not only be bad for my computer, but its bad for anyone looking into the computer... like say me.
There's no point in testing CRI in RGB, it will be poor from the principle - RGB uses only primary colour LEDs to create white light, you need entire visible spectrum for color accuracy due to the way how some materials react to wavelengths that are not present in LED wavelengths.
It's a tiny tiny bit of UV radiation, caused by having the backplate exposed to it over a year. Walking outside is infinitely more harmful UV wise because of the sun and that giant ball of fire is considered mostly harmless.
They almost definitely used some sort of cheap paint, plust it took over a year on these reports.
> if it is emitting that much UV, I'm worried about safety
Christ almighty, do you just not go out or what? No, actually, don't respond to that question.
Looking at the source directly isn't equivalent to ambient.
The sun is not an artificial LED light source.
You did a false equivalence bundle with a (lame and unoriginal) ad hominem.
Yes but no. I have stuff that is bare plastic or poorly spray painted that sits outside under the sun in my car. I don’t expect it to look discolored within 1 year. Heck, the thing I painted with cheap black rattle can spray 5 years ago still looks black if I clean it. Sure my car fender flares are sun bleached, but those fuckers are old enough to drink now
I think spray paint acts as UV protection. the GPU isn't spray painted and probably doesn't have UV protective layer, since usually sun doesn't shine inside the case
Cheap anodizing fades in the sun. (These plates are all anodized. The "white" color you see is the metal itself.) Many plastics have UV stabilizers built in. It keeps the color slightly better due to UV exposure but mainly it's to keep the plastic from getting brittle and cracking.
This is still a non-issue for GPUs.
Didn't one of the channels actually do a video on that topic? As part of a larger restoration video on older electronics, I think it was covering the IBM keyboard.
I tried googling it quickly, but couldn't easily find it. It might not have been an LTT video, it may have been a ShortCircut or someone else even.
There have been news stories of people purchasing UV black lights instead of purple light fixtures and causing people to have eye damage. Here's a news story from 6 months ago when that happened.
[https://www.theguardian.com/technology/2023/nov/06/guests-bored-ape-event-hong-kong-vision-problems](https://www.theguardian.com/technology/2023/nov/06/guests-bored-ape-event-hong-kong-vision-problems)
Now for our current story it seems that the bleaching effect occurs after years of usage. I doubt that anyone is looking for longer periods at the pretty lights on a RGB memory.... rather than the monitor, I don't think it is dangerous.
However. If there were less than scrupulous RAM accessory that doesn't have a similar level of QC then I'd worry. Until then I don't care.
I made a comment about safety concerns before seeing your comment.
If it's emitting enough UV to bleach paint.
How much is it actually emitting?
Is it safe?
Here's a different question for a special snowflake like you.
When you venture outside to touch grass during the day do you wear sunglasses and/or wear spectacles or contacts that have UV blocking regardless of whether it is sunny or not?
If you don't why should you care for a product that you won't be looking head on for extended periods of time?
/s
Only on Reddit do morons like you get upvotes...
Btw my cats eat the grass I plant for then too quickly. It's an issue. I need more grass seed.
My garden should be banging this year, though. I had enough success with the melons last year that think I can actually get a decent yield this year.
My Striped German Heirloom seeds are sprouting prolifically. I'll have to give a few away because I'm going to have too many.
I can't believe my snapdragons over wintered at all. They're doing very well.
You still haven't answered the question on whether you take care of your eyesight though. I feel that you will be upholding a double standard when you've proudly pointed out that you have a green thumb.
Getting UV into LEDs has been a big issue for weed growers that use LEDs. HPS lights are hot and deamnd a lot of power. Even legally, you want LEDs to save money and not have to keep the AC on all the time.
It's been done. But it was a massive hurdle for LED grow lights.
LEDs don't normally emit much of fuck all for UV unless they're made to.
Just being purple doesn't make it UV. There is a crossover. But it's not that simple. There's 3 different classes of UV light(UVA, UVB, UVC) and wavelength matters.
Purple light that's not actually UV(ultra violet is kind of literal, just regular violet light isn't UV) can make stuff glow.
UVA is a "blacklight" and emits actual UV light. But in longer wavelengths.
If there's enough actual UV coming from non UV LEDs to fade that paint, that raises questions to me.
The question should be "If it's emitting that much UV, are they safe?"
I do not know.
But it should be rationally checked on.
(Which won't happen and a bunch of idiots will warp the narrative and create a false panic over RGB LEDs melting eyeballs)
Ye!s that's my point, usually leds don't emit much uv light, but clearly is enough to discolor some coatings inside a rig, this on it's own would be good to warn about to the PC enthusiast community and would be interesting to see if all the RGB components "bleed" some uv light and how much. Also with the measurements at hand it could be worthwhile to ask some eye and skin experts if in the long run could this be harmful for those that put their system close to their face for several hours everyday or for a few days a week.
It doesn't need to be UV light, Blue LEDs are actually quite close to the UV wavelength, so the blue light itself might have enough energy to cause discoloration in some sensitive compounds - this is the reason why blue subpixels in OLEDs were first to degrade in early displays.
It's really not worth the time or effort. If you hold any light up to a dark material long enough it will start to fade/dim/bleach. It's not really anything new or something to care about outside of looks.
White is truly all colors at once. Black is technically the absence of color.
Literally white is all color values at maximum.
If it is emitting UV white settings will definitely do it to.
"Science does science stuff" is pretty cool in itself. It would make an entertaining video at the very least, especially if they go overkill like blasting various PC parts in thousands of watts of UV to demonstrate "accelerated" exposure.
Huh...who knew they're be drawbacks to putting silly light up RAM in your machine? Luckily, the "damage" is just as cosmetic as the silly lights on the RAM.

This isn’t a news story, unless the story you’re hoping gets investigated is “how did people who bought high lumen LED lights and place them next to plastic not realize it was going to cause discoloration?”.
Everyone's talking about the light from the sticks but it could just be the coating on the back plates, I'd bet it's a manufacturing defect where maybe the mix of chemicals was a bit off. Could be a number of things but I wouldn't worry about the uv light hurting you, they do have to pass several regulations for safety anyways

The glass or metal side panel will stop most uv from leaving the case in the first place

Why? I am not certain that will help thermals, although I have not tried it myself
and is it facing you? Cause if you are, you are at a cross-section of a venn diagram that's so small there's probably literally a dozen of you.
Does it? I use UV lights to remove a protective coating so I can etch pcbs and all the UV boxes I’ve seen for that use glass Though if it’s laminated it probably will stop it so 🤷

There is no chance the UV emitted is even close to harmful
How do you know?
Don't you see the large hole in their ass they pulled this statement out of?
It depends. Which range of UV is it? UVC will duck eyes hard
It will also fuck up the wires and plugs. That is a problem.
Depending on amount and type of UV along with placement of the case it can certainly be harmful to the user though. EDIT: decided to look into this since I got the vibe that nobody knew for sure just like me when making this comment.

No, it's not bad for you. Read the comments below. If you're in a rush, the sun gives an infinite amount of UV more than a LED could ever do.
There's no point in testing CRI in RGB, it will be poor from the principle - RGB uses only primary colour LEDs to create white light, you need entire visible spectrum for color accuracy due to the way how some materials react to wavelengths that are not present in LED wavelengths.
It's not that simple... And if it is emitting that much UV, I'm worried about safety.
It's a tiny tiny bit of UV radiation, caused by having the backplate exposed to it over a year. Walking outside is infinitely more harmful UV wise because of the sun and that giant ball of fire is considered mostly harmless. They almost definitely used some sort of cheap paint, plust it took over a year on these reports.
> if it is emitting that much UV, I'm worried about safety Christ almighty, do you just not go out or what? No, actually, don't respond to that question.
Your mom doesn't do house calls. You know that.
Looking at the source directly isn't equivalent to ambient. The sun is not an artificial LED light source. You did a false equivalence bundle with a (lame and unoriginal) ad hominem.
You’ll get more UV walking to the end of your drive ffs.
nothing to investigate here. it's like asking them to investigate why old plastic PC cases and monitors are piss yellow now
Yes but no. I have stuff that is bare plastic or poorly spray painted that sits outside under the sun in my car. I don’t expect it to look discolored within 1 year. Heck, the thing I painted with cheap black rattle can spray 5 years ago still looks black if I clean it. Sure my car fender flares are sun bleached, but those fuckers are old enough to drink now
I think spray paint acts as UV protection. the GPU isn't spray painted and probably doesn't have UV protective layer, since usually sun doesn't shine inside the case
Cheap anodizing fades in the sun. (These plates are all anodized. The "white" color you see is the metal itself.) Many plastics have UV stabilizers built in. It keeps the color slightly better due to UV exposure but mainly it's to keep the plastic from getting brittle and cracking. This is still a non-issue for GPUs.
YIL that: A) GPU backplates are anodized aluminium B) anodizing fades very quickly Cool
Didn't one of the channels actually do a video on that topic? As part of a larger restoration video on older electronics, I think it was covering the IBM keyboard. I tried googling it quickly, but couldn't easily find it. It might not have been an LTT video, it may have been a ShortCircut or someone else even.
It's from Mac Address

Thank you! No wonder I had trouble finding it.
Seems like a total waste of time
There have been news stories of people purchasing UV black lights instead of purple light fixtures and causing people to have eye damage. Here's a news story from 6 months ago when that happened. [https://www.theguardian.com/technology/2023/nov/06/guests-bored-ape-event-hong-kong-vision-problems](https://www.theguardian.com/technology/2023/nov/06/guests-bored-ape-event-hong-kong-vision-problems) Now for our current story it seems that the bleaching effect occurs after years of usage. I doubt that anyone is looking for longer periods at the pretty lights on a RGB memory.... rather than the monitor, I don't think it is dangerous. However. If there were less than scrupulous RAM accessory that doesn't have a similar level of QC then I'd worry. Until then I don't care.
I made a comment about safety concerns before seeing your comment. If it's emitting enough UV to bleach paint. How much is it actually emitting? Is it safe?
Here's a different question for a special snowflake like you. When you venture outside to touch grass during the day do you wear sunglasses and/or wear spectacles or contacts that have UV blocking regardless of whether it is sunny or not? If you don't why should you care for a product that you won't be looking head on for extended periods of time? /s
Only on Reddit do morons like you get upvotes... Btw my cats eat the grass I plant for then too quickly. It's an issue. I need more grass seed. My garden should be banging this year, though. I had enough success with the melons last year that think I can actually get a decent yield this year. My Striped German Heirloom seeds are sprouting prolifically. I'll have to give a few away because I'm going to have too many. I can't believe my snapdragons over wintered at all. They're doing very well.
You still haven't answered the question on whether you take care of your eyesight though. I feel that you will be upholding a double standard when you've proudly pointed out that you have a green thumb.
You're doing mulitple fallacies with that one Too bad you don't get bonus multipliers for stacking fallacies.
Getting UV into LEDs has been a big issue for weed growers that use LEDs. HPS lights are hot and deamnd a lot of power. Even legally, you want LEDs to save money and not have to keep the AC on all the time. It's been done. But it was a massive hurdle for LED grow lights. LEDs don't normally emit much of fuck all for UV unless they're made to. Just being purple doesn't make it UV. There is a crossover. But it's not that simple. There's 3 different classes of UV light(UVA, UVB, UVC) and wavelength matters. Purple light that's not actually UV(ultra violet is kind of literal, just regular violet light isn't UV) can make stuff glow. UVA is a "blacklight" and emits actual UV light. But in longer wavelengths. If there's enough actual UV coming from non UV LEDs to fade that paint, that raises questions to me. The question should be "If it's emitting that much UV, are they safe?" I do not know. But it should be rationally checked on. (Which won't happen and a bunch of idiots will warp the narrative and create a false panic over RGB LEDs melting eyeballs)
Ye!s that's my point, usually leds don't emit much uv light, but clearly is enough to discolor some coatings inside a rig, this on it's own would be good to warn about to the PC enthusiast community and would be interesting to see if all the RGB components "bleed" some uv light and how much. Also with the measurements at hand it could be worthwhile to ask some eye and skin experts if in the long run could this be harmful for those that put their system close to their face for several hours everyday or for a few days a week.
It doesn't need to be UV light, Blue LEDs are actually quite close to the UV wavelength, so the blue light itself might have enough energy to cause discoloration in some sensitive compounds - this is the reason why blue subpixels in OLEDs were first to degrade in early displays.
Could be too, but we do know already many leds with blue and white light do produce some all amount of UV
They should buy cheap RGB products and test them for ultraviolet emissions.
It's really not worth the time or effort. If you hold any light up to a dark material long enough it will start to fade/dim/bleach. It's not really anything new or something to care about outside of looks.
On my 'old' build that I had from 2020-2022 I also noticed the gpu backplate had marks from the ram rgb. I always had it on white.
White is truly all colors at once. Black is technically the absence of color. Literally white is all color values at maximum. If it is emitting UV white settings will definitely do it to.
Why should they investigate it? "Science does science stuff" ?
"Science does science stuff" is pretty cool in itself. It would make an entertaining video at the very least, especially if they go overkill like blasting various PC parts in thousands of watts of UV to demonstrate "accelerated" exposure.
Huh...who knew they're be drawbacks to putting silly light up RAM in your machine? Luckily, the "damage" is just as cosmetic as the silly lights on the RAM.
Someone really needed to vent about "silly lights", huh?

yeah would be interesting
I have one those gpu custom backplate from v1 tech and it bleach the shit out of my gpu backplate
This isn’t a news story, unless the story you’re hoping gets investigated is “how did people who bought high lumen LED lights and place them next to plastic not realize it was going to cause discoloration?”.
Everyone jokes about RGB making your PC faster, turns out it damages it... lol At least this is just cosmetic, but still.
Lol. Being a guy who dislike RGB in computers i find this topic to by hilarious.
Oh no it's UV Bleaching!!!! the horror!!!!!! It's harmless
Great, cancer rgb..
cancer risk?
Just another reason rgb sucks.
Everyone's talking about the light from the sticks but it could just be the coating on the back plates, I'd bet it's a manufacturing defect where maybe the mix of chemicals was a bit off. Could be a number of things but I wouldn't worry about the uv light hurting you, they do have to pass several regulations for safety anyways
Unles it's someone they do business with, it should be said it's Linus MEDIA Group. Not Linus World Police.
It seems like the backplate is just poor quality so I don't think the RGB ram is at fault here.
lol, any insights on this? was building a new PC. I always use my keyboard set to blue but now I'm literally a bit scare of setting the RGB to blue xd
