I'm 45 yrs old and ruined my eyes when I was just 17yrs old. I was helping out at the scrapyard where my Dad worked and came across a bunch of Metal Cylinders. I unscrewed them to find they contained FULLY Transparent Fluorescent Tubes. After wiring a ballast up and having tested 9 out of the 10 I found, I saw the Warning on the end of the tube whilst I was looking at the beautiful Ribbon shaped Bluey Purple light passing through the Tube!! It said, in Bright Red Letters..."UV-C. AVOID PROLONGED SKIN EXPOSURE. AVOID ANY EYE EXPOSURE. RETINAL DAMAGE WILL OCCUR"!!! Later that night I had a slight headache when I went to bed and at 3am, Pain like I have never known! I spent the next 2 weeks in the house recovering and HAD to wear dark sunglasses AT NIGHT, it was that bad. They're not toys. Don't piss about with them and stay safe around them. My eyesight was irreparably damaged and that diagnosis was from a top ophthalmologist through Private health care! "Never look at UV-C with remaining eye!"
i have been working around high power uvc lamps since i started work in 79 as a school leaver, we used them to cure printing inks. the early machines use to spill light all over the place and were not safe. they used very high voltage lamps that were powerful enough to set light to any material that got stuck inside the drying tunnel. we became very good at putting fires out, some were water cooled with the lamp inside a glass tube surrounded by flowing water and a cooling tower on the roof of the building. the modern ones are all enclosed and shielded low powered LED. i had two lamps similar to the one on show in a uvc pond filtration system. it worked very well.
Reminds me of the first time I saw someone welding, and it made this same beautiful blue light. I just couldn't stop watching because it was so beautiful. And I payed for it with multiple days of sand eyes. Not sure about retina damage.
Our lot regularly misplace multi-tine fork/shovels to DC, or for variety go and spike the wrong 33KV cable (admittedly the latter also involves some singeing = > )
Good description, I've had welders eyes twice ,and once would have been enough , both times it came on at night and first time I dreamed I was working under a pickup and my eye's dribbled full of gravel , it woke me up , that was really bad since then I've heard of a lot of things you can do to stop the pain , such as an eye drop of milk and honey , but I had no clue about what to do at that time
It's not the sand in the eyes that's an issue. It's the fact that the sand doesn't leave for hours. Eyes open Or Eyes shut. Every rest is agony, and so is every blink. It's a hell you do not escape
@@nathantschetter1264 I have had it a few times as well. I think it was clearly due to the position I was welding and the light coming in under my helmet? Though I have not welded for some years and if I ever do I will only weld with a hood cover.

I work at a plant nursery and one day i was changing an air filter on one of the a/c units. There was a similar bulb inside the ac unit to kill any unwanted bacteria. I only looked at the bulb for maybe 5 seconds from a distance of 2-3 feet. That evening I woke up in the middle of the night and it literally felt like I had sand in my eyes. I have never felt anything like that before or since, and it wasn't until watching this episode did I understand what had happened. Now I know, it was that d%^* light ! Thank You bigc !!
Its generally a good idea to turn off any electrical device before messing with it, and reading an instruction. Most of devices even if are turned off, are still holding a charge.
They are actually becoming common on home HVAC units so beware if you're a DIYer. Should be in an area you won't commonly acess and most units you can just unplug.
Oh noo! The memories, I found a bulb like this when i was a kid. Had no idea what it was. We set it up outside to attract insects. Little did we know we had been burning the skin on our eye balls for a couple of hours. Woke up the next day with my eyelids sealed shut! Was out of school for a couple of days.
The allure and beauty of the light reminds me of the Goiânia disaster in which a radiotherapy component from an abandoned hospital was stolen by people looking for scrap and dismantled, with the beautiful glowing blue and highly radioactive powder contained within removed. It was then passed around and handled by several people including a child and a woman who thought it would make for a nice eyeshadow. 4 people died and dozens more were exposed. Can't say I trust pretty glowing blue things.
Speak for yourself shithead!! I got a new QHDR monitor (q is quad for all uv bands + HDR) and I can burn my eyes with this video! it feels like beach sand blew into my eye! You all are too stupid to have it though, I'm going to replay this video all night because you suck!
That was a _very scary_ long time that you spent with the lamp on next to your skin and eyes, knowing what this radiation does. (With regards: A fellow owner of _two_ death lamps.)
25watt globe, 15cm from the skin for 30 seconds will case sun burn in that location and skin will peel in a few days. I've done that to myself. The light does burn quickly. Distance is a factor.
It's not only the power. These lamps put out alot of Ultra deep UV light. That is very harmfull for skin and eyes. Ofcourse in combination with enough power but still, you do not need alot of power for ultra deep UV to damage cells
dont let slag get on your hand either... im a blacksmith i know the smell and it dont feel good ill tell you that. *BE AFRAID OF THE FIRE AND WATCH WHAT THE BLACKSMITH IS DOIN AND YA WONT GET BURNT TO HELL*
Theres a company selling a 4 bulb human sized UCV device that is meant to be wheeled from room to room in hospitals to sanitize them. However I believe they are supposed to run for 4 hours, also the cover on it pops off and doubles as a warning sign, because going into that room while one isnt exactly healthy, it also has sensors to yell at human who are near it while its on before turning off.
I've actually seen one of these used "properly". I worked in a lab in Turkey and they had a room that had to be sterile for working with cultures. They had one of these lamps to sterilize the room when it wasn't in use, that you could turn on from the outside. I think there was a rudimentary safety system in that you couldn't turn in on if the normal lights for the room were on (i.e. it was occupied) but scary nonetheless.
This reminds me of an incident when an OAP in our family managed to get a hold of these for his garage.. the reason being is he hated frosted bulbs and it was to replace the two clear halogen bulbs.. My ears pricked up as someone mentioned he was moaning about his new ‘energy saving’ lights not working and were ‘weird baby blue’ in colour.. sure as anything they were two germicidal bulbs in E27. No idea where he got them from.. he had been working under them for a good few days (using a bench light). Another ‘trigger’ for me when his son also said they set off his Transition glasses... that’s when I got involved... awhile ago but I do wonder how on Earth he managed to get a hold of them, as he was far from computer literate!
3:36 UV lamp tubes are made of fused quartz which allows the UV to pass through. Standard florescent tubes are made of glass that allows UV to pass but most of it is absorbed by the phosphor coating inside the tube to create visible light. Note any damage to the phosphor coating (this often happens at the ends of the tube) will allow UV leakage.
Was about to say the same thing. We have huge 50 Watt or so UV-C tubes at work for industrial water-sanitizers. It warns about the use of quartz glass on the package (besides a whole bunch of other warnings and logo's)
Nope, normal lamps usually have borosilicate glass because of its very low thermal expansion. Soda-lime-silica glass would break due to the high thermal stress.
Normal incandescent lamps (the now mostly banned kind) usually have a soda-lime-silica envelope and a lead-potash-silica stem (lower conductivity at high temperature avoids glass electrolysis in the pinch seal). Some larger discharge lamps and other specialty lamps have borosilicate outer envelopes. As far as I know, germicidal variants of normal fluorescent lamps use a soda-lime based glass formulated for low attenuation at the mercury 253.7 nm line, while higher arc loading industrial tubes use quartz envelopes. The easiest way to tell is to look at the glass-to-metal seal, soft glasses (soda lime, lead potash) often use dumet wires which appear red inside the glass, hard glasses (borosilicate) often use tungsten wires which appear brownish or yellowish, and quartz uses molybdenum foil seals.
_blocks any UV not absorbed by the phosphor_ Nope. But thanks for playing. They leak enough UV to bleach anything left under them for prolonged periods. (eg. MM fiber cables in a data room where the lights are always on.)
"Germicidal UVC lamps can be manufactured with one of two different types of glass - Quartz Glass or Soft Glass. Germicidal soft glass is a highly refined and pure type of soda lime glass, similar to that which is used to make visible light fluorescent lamps. ", "Transmission of UVC is approximately 9% lower than that of quartz lamps, leading to less initial UVC output. Soft glass will not allow the transmission of UVC wavelengths below 200nm and therefore can not be used to produce ozone at 185nm." lightsources2015.wordpress.com/2015/04/02/tips-on-how-to-determine-if-quartz-or-soft-glass-germicidal-lamps-are-best-for-your-uvc-application/
As nobody seems to have mentioned it. I will also point out just how dangerous Ozone is, both itself and in reaction with other chemicals. So please ventilate the room well if using one of these. Also, for those people thinking of using this for sterilising rooms, remember that the UV-C will badly damage plastics, nylon, etc very rapidly. Painted surfaces, silk and other materials will also be badly affected. Don't use if you have cheaper man-made carpets.
I just bought one of these and let me tell you, I could smell the ozone after only 5 seconds of operation. I just disinfected my bathroom for 5 minutes and the entire floor wreaked of ozone. The bathroom had no smell after the disinfection (except for the odor of ozone). Before the disinfection, the bathroom had a very moldy and dirty smell. UPDATE: Due to COVID-19, I regularly use the lamp to sterilize my phone, keys, and other common items. Btw these lamps can be found all over eBay.
Cleaning companies like servepro use ultraviolet ozone generators to kill mold and it neutralizes the burnt smell in houses after a fire. Ozone is a disinfectant also, it degrades into O2 and O- which is an ionized free radical, it also forms OH- free radicals when dissolved in water which want to oxidize something badly and organic molecules are their favorite.
Mushroom clouds look awesome too, but we know the problem with those. I worked for a company that made biological safety cabinets, (fume cupboards) and they had a UV c tube in the conventional fluorescent tube format but they didn't make a blue glow at all. They only made a slight purple glow at each end. Anyway these things are extremely dangerous. If you were to turn one on and fall asleep, you'd wake up with a nasty sunburn and potentially skin cancer. Thanks for sharing. 😉👌🏼
This begs for a test. Take toilet water or pond water and put a few drops on different Petrie dishes. Expose one at 10cm, another at 20cm, 40cm, ... for 5 minutes. Last of all have one dish with no exposure. Wait a few days and look at the results. How well and how far does the light make a difference?
Sorry about that that was intended for Hagbard Celine it may have been a wind up how can they be so stupid as to subject kids to UV light...sorry again
migette1 No problem, but my guess is that the joker that said he uses the light for kindergarten kids is likely to be making it up just to get a reaction from people.
Regular fluorescent tubes have soda lime glass (not borosilicate) which is basically impermeable for any kind of ultraviolet, and these tubes, if properly made, have quartz glass. I say properly, because if the glass fluoresces at all, it's not pure quartz glass. UV-C is greatly attenuated in air and it diminishes after several metres. It's absorbed namely by oxygen, and basically spent on creating ozone. Same process as in stratosphere. At power of around 20 W skin exposure at 1 m should last for no longer than 30 seconds. Obviously, the closer one is and the more powerful the lamp is, the greater the skin damage. Of course, eyes are much more sensitive than the skin. It's a poor way of direct sterilization because microbes in crevices are shaded and will survive. As a generator of ozone, it's ok. Having one installed in the airducts is great for keeping the air clean but *only* if the output air is reacted with a reducer to destroy the ozone. Ozone is an extremely power oxidizer, very corrosive for almost all organic molecules. You don't want to breathe that.
@@sammamishq7688 You can filter your room with a HEPA air filter. They remove particles as small as 0.3 micron. Some of them come with activated charcoal filters which are good for odor removal.
@U K I don't think it's that bad if you're in and out of there but if you take hour-long showers it might be a little worse on you. At least that's my theory I don't have anything to back this up with. I also hope it was some assistance to you and you not quite dead yet
I spent a few minutes getting Google Translate app on my phone ready to translate the text on the box at the start, only for Clive to turn the box over and read it in English.
For the uninformed.. all mercury lamps work this way, the white coating on the inside (edit: phosphor) is what changes the light frequency from uv to visible...
I got arc flashed on my first welding job. Didn't feel anything until about 3 hours after finishing. First thought I had an eyelash in my eye then all of a sudden really sharp, gritty pain, my eyes are streaming, hurting so much I can't even open them. Spent about 10 minutes thinking I was going blind then it occurred to me what had happened. Couldn't open my eyes for 2 hours. I did manage to roll a... erm... "herbal cigarette" (for pain relief) completely blind which I was quite proud of!
Yeah. I could open my eyes after about 2 hours and put some eye drops in. For about 2 days afterwards I had those white lights constantly in my vision that you normally get briefly from looking at a bright light. Itchy pain for about 3 days. Not a nice experience!
Not fun.. Had a neighbor that worked for a lighting company have to work on germicidal lamps used at an animal shelter to sanitize kennels. Call came in because they were not working. While he was working it it the lights came on, and cooked his cornea. He went blind for a few days and said the feeling was like someone threw sand in them.
Right. I was warned about looking at one, so I don't. I have 2, one inside my air ventilation duct, and the other one is in a tooth brush sterilizer I built, and it has an interlock witch so it only operates when the box is closed. Works great for that. Picked up my replacement bulb on Amazon for 10 bucks.
Back in the beginning of covid I ordered 2 uvc bulbs with ozone. Not sure if it ever really did anything for covid, but once the room is thoroughly ozoned up and you let it dissipate, the room smells super fresh. If you have mold or mildew problems, this will also kill that. But like he said, don't expose yourself, I put mine in a lamp without a shade and plugged it into a smart plug. Then I could leave the to room, close the door, and turn it on/off. Ozone does STINK and takes a hour or two to go away. Keep in mind it may damage other stuff in your room also, even paint.
My Father was an Aeronautical Engineer that ended up becoming a part owner of an HVAC company, after the second world war II he came home and sold for this company involved only in commercial HVAC sales. I remember him bringing home a small commercial unit that would dispense ozone. When you switched the unit on the unit would pass a very large stream of ozone and make a large wind going through the unit even though there was no fan, the smell from the first second would make you almost ill. When my sister nearly lost her leg in a motorcycle accident he would turn the unit on while we left the home, when we returned he would turn off the breakers outside to turn the unit off, then hold his breath, go in the home and open the window to vent the home, that would kill 99.9 percent of the germs in the house, she never did get a secondary infection, lol..... Oh well, long story. fun times in the early 60's......
hii, can you still locate that device that you were talking about that your dad purchased to kill germ in house when no body around ? i am very much interested. thanks andrew
Sadly this unit has disappeared from my parent's things. Neither of my sisters has any ideas... The unit was about 12"x18"x8", it had a grill in both front and back with a couple of controls, you could adjust the strength of the unit from almost no ozone to a strong wind, the wire would glow from the current to a bright blue, I would love to look at it. at full force (all on) the wind was like you turned a good sized fan on! Dad didn't buy the unit, he owned a company that represented commercial HVAC companies, they gave him the unit. By the way, I'm 70yrs old.
It is essentially a welding arc in a glass tube. The sand in your eyes feeling is known as welders flash, and the burn pork smell of your skin is a common sign of arc burn from unprotected skin during welding.
Well at least the welding arc is bright enough to keep people not wearing protection to look at it for long enough to get a flash. Also most people know the hazards and to look away if for example welders are welding in the street or other public places. UVC germicidal bulbs on the other hand aren't nearly as bright as a welding arc and one could definitely look at their beautiful turquoise glow for hours and get permanent damage to their eyes afterwards without realizing it at first. Much like the sun that is bright enough to keep people from looking at it long enough to get serious eye damage from the UV in itself. (Although it's "only" UVA and B as the UVC is blocked by the ozone layer in *most* parts of the world). But there are blacklight tubes for parties that emit lots of UVA and almost no visible light and one could look at them long enough to harm their eyes without realizing it. (It's mostly eye strain and not much "sand" but still not good as it could lead to an increased risk of cataract and/or macular degeneration later in life).
Normally the "special glass” for these things is quartz, as in Quartz Halogen car headlights. Quartz was also used in the little windows used to erase old style eproms. Touching it with your fingers shortens the life of the quartz. Frankly I would not have powered that thing up, unless I was in a different room, watching via video link!
if you clean it off in a spirit before turning it on it will be fine. The oils left on it create uneven heating witch can shorten the life of the light due to micro fractures.
The quartz degradation only happens with lamps that run hot enough for skin oil residue to be soluble in it, which are usually halogen and certain specialist bare arc tube HID lamps. Lamps like this don't get anywhere near that hot. Also, these often use low/no iron glass as that is cheaper.
@@randacnam7321 I have a 250W Fc2 metal halide lamp, so the arc tube is enclosed, however the outer bulb still gets quite hot. In fact I wouldn't be surprised if this *outer* bulb was hotter than a halogen one. Therefore I avoid touching it with my bare hands and clean it with isopropyl alcohol just in case. But would it be as safe as you said in your previous comment to run it without cleaning it first ?
I could see myself building some "air cleaner" station that filters dust out, takes humidity down and then passes the stream along one or two of these...
Some high-end aquariums use a filtration system that includes a UV lamp ( enclosed ) to filter water as it is pumped through & kill algae & other water-borne parasites- harmless to the fish of course. Wouldn't recommend it for an air cleaner unless you only had it turned on for short periods- it gives off a strong bleach smell, hence why Clive said you need to leave the room while it's turned on, then leave the windows open to clear out the smell after you turn it off...
You're probably better off using a normal ozone generator (as seen in a recent Clive video) for that. the point of these lights is to sterilise surfaces, not just the air passing right over them.
SuicideNeil It's not because of the smell although ozone becomes annoying to smell after a while, but because of the UVC radiation which isn't too good for your skin or eyes.
Eryk- yeah, I did watch the video with the sound turned on- and the previous one he talked about too, but thank you all the same; sitting in a room that smells strongly of bleach wouldn't be any fun was my point. You'd only suffer skin/eye damage if the bulb was exposed- which it wouldn't be if it was enclosed inside of a filtration unit, as implied by mazeFrame.
Hypothetically, if you have mosquitoes in the room, would it help convincing them to live shorter ? As in, not anymore when you enter the room 2h later ? Of course, at that point, all colored stuff in that room is also bleached...
Especially since it is the blue Spectrum and combined UVC it is almost instantly deadly to mosquitoes, larvae, beetles, flies pretty much everything. You Couldn't stop warning people about this bulb, kudos for that. This one's dangerous folks. 👌
I don’t think that It will bleach things. Atleast not a lot. I haven’t noticed it yet with my weaker UV lamps. I need to get one of these, But I’m on 110V I hope I can use it on 110V.
The UV can be reduced by reducing the current through the tube. But the glass still does emit the UV, just in less intensity. If you want a lamp that color, but not so dangerous, you can have one made at a neon sign shop from soda glass. I have a few of them. They are very pretty but don't emit much light.
We’ve got like these 6ft tall UV lights at the school district I work at. Hospital grade and we use them to kill germs and any illnesses. They work fantastically but you need to be really careful if the teachers have plants or animals in their rooms. A few years ago a teacher had 2 turtles in her room. Light was on for 3 hours and killed both turtles. So ya. This light is potent.
just be careful with these things. A few minutes is enough for eye irritation for the next few days. Also for the ozone, if you can smell it, it will irritate your lungs, what you definetly don't want in a time of the corona pandemic (you will be infected easier). BTW I use it in a cardbord box to sterilize everything I buy at the store, also for my clothes, which I wear on the street. I don't know how effective is the ozone for killing viruses. Anyone an idea about that?
Péter Szőllősi I read about the ozone and it is very effective but the effects are erratic. Good against germs and will also cancel organic smells but chemicals like glue used in carpets is just turned into something else which is probably just as toxic. So don’t rely on ozone on chemicals.
doesnt cause cancer. sunburn maybe. Its for short exposure in the winter to give vitamin D back your body. was used to treat skin diseases . Its safe when used properly. I have an old sun kraft and use it weekly. NO cancer no illnes and my skin looks great
You can actually find these in garden/hardware stores, they are commonly used in garden pond sterilizers. These lamps are also really good at wiping UVROM's (EPROM) in a matter of seconds.
@@jamestreese4 Erm, there are legit reasons to want to wipe a UVROM/EPROM - for example if you do DIY electronics and want to repurpose one you harvested from a donor board for some project.
Quartz based glass passes UV, they use bulbs like that for high intensity photo chromatography when processing certain biologic samples. There will be a broad spectrum tungsten lamp and a UV lamp and a precision controlled prism that will pass certain wavelengths at precision angles, and a photo detector to measure the transmissivity of the sample. The sample holders have to be quartz to measure any UV.
Brand-Tech makes plastic, disposable, UV transparent (down to about 230nm) cuvettes which are about $1 each. www.brandtech.com/wp-content/uploads/cuvettegraph.pdf
Actually the monochromators are usually based on diffraction gratings rather than prisms. And for UV spectroscopy or UV detectors for HPLC etc they usually use some interesting (aka expensive) types of lamps, e.g. deuterium arc lamps.
David Robertson those diffraction gratings are a BITCH to calibrate, I remember that much. It's been like 10 years since I've touched that kind of equipment. HPLC pistons I also remember being expensive as they were typically man-made Ruby to handle the pressure, and the little windows were man-made sapphire. I'm glad I don't work in that field anymore.

Hospitals have a sterilization light that they wheel into rooms that had patients with particularly nasty infections. Someone posted a picture on Reddit where all of the cabinets in the room were open and the garbage cans were on their side facing the light.
It's not sterilization, it sanitization. It brings the level of viable germs to low values, but it will not kill every one of them, as well as their possible spores. if this was effective, ethylene oxide and plasma and gamma rays would not have to be used, and they are used.
The UVC lamps are common in marine and freshwater aquaristic. I'm using it in my nano-reefs all the time. But they are hidden in black cases obviously.
In my younger days I worked in blown film plastic factories and we used a device that put an "arc" across the plastic film to create small pits so when they printed the film the ink had somewhere to pool and set (not technically correct but good enough for my tale of woe). If the film wasn't treated then the dry ink would just peel off when sellotape was applied and removed. One night the pipe that exhausted the ozone to the outside broke. It was a large factory about 75 metres long, 25 metres wide and 15 to 20 metres high. There were two rollup doors that extended more than half way to the top of the building and there was a slight airflow. We had both of these doors open and all three of us (it was on the night shift so minimal staff) got ozone poisoning. It was like the hangover from hell; *VERY* unpleasant and it took a few hours after finishing work for the "hangover" to subside! I later became a Network Engineer and made myself a tad unpopular with my employers when I would point out the crisp smell coming from the high volume printers and especially photocopiers was a poisonous gas and proper ventilation of the photocopy rooms was required. Also suggested that the high volume A4 printers should not be sitting next to someones desk but rather a few feet (a metre) away. I really came to hate the smell after my nightmare in the factory.
I suspect the metal cylinders aren't getters, but "givers": sintered lumps of mercury amalgam, that give off mercury when heated. They're a simple and convenient way to deliver a specific amount of mercury, without having to handle actual liquid mercury. It was interesting watching the mercury propagate through the tube when you had it lit too: the tubing nearest the cathodes/givers had the bright blue mercury vapor look to it, while the tubing farther away showed the paler discharge of just the carrier gas (argon?). I made a tube once with neon and mercury and when I first fired it up, it light the brilliant red of a neon discharge, and I could watch the blue move through the tube and take over as the mercury vaporized. I wish I had filmed it.
They may indeed be a mercury amalgam for controlled dosing. I have a neon mercury tube with a dip in the middle to trap the migrating mercury when the tube is run on DC. It takes a long time, but the residual mercury at the electrodes finally migrates away and the tube then lights more or less half and half red/blue.
The UV box I use for curing photopolymer is basically just a naked 175W mercury vapor arc tube in a box with ducted exhaust. It can turn white pvc brown in a few minutes, and the light leaking into the duct makes the hose brittle.
Cataracts are a thing. Had to have mine out at age 52. I spent too much time without eye protection around black lights as a youngster also, we didn't know about UV protection in the '70s.
I can just imagine all the people who watched this video thinking it's a great way of getting out of cleaning the bathroom; "Oh but the light is killing all the bad stuff!" - "Yeah, but the bog still has your skids all over it!!!!"... :P
Reminds me of the time I had my laser eye surgery. There was this zapping noise and a distinct smell of burning flesh from my eyes (after the guy had stuck a suction cup to my eye, made it temporarily blind and cutting it open a bit). I can imagine how someone might get a little upset about the whole process. End of sidetrack.
Corneal XL (Cross-linking) treatment is great 'fun' as well. You're there 'live' all the time while your eye is spread wide open by a spreader placed on your eyelids, while the treatment consists of all kinds of droplets and eventually riboflavine droplets that both protect your retinea as well as building new cell-interconnections in your corneal tissue when exposed to.... highly concentrated UV-light.Yes, you have to look straight into higly concentrated UV-light for 30 minutes straight...
@@bigclivedotcom That's what it looks like from the photos yeah. And this incident has also reminded folks of the 2017 fashion show incident you talked about in this video. Too bad none of the Apefest lighting crew remember that.
I just bought one of these to use periodically in my slightly damp basement. I switched it on to make sure it was working and looked at the light for less than 5 seconds, probably only even 2 - 3 seconds as I glanced at it a couple of times at a distance of about 2 feet. Now I'm shit scared of it and that I have blasted my eyes. Somebody, please tell me I haven't given myself arc-flash in this short time? I need some reassurance and have now put it on a remote switch so I can turn it on from outside the room. Help! I'm still a bit scared! EDIT - 24 hours have gone by and my eyes are fine. I was just panicking!
Stigstigster Good to know lol. I purchased one of these recently to sterilize a room of microorganisms. I will be setting it up soon. I’d like to make sure it works but also plan on normally powering it on/off remotely with the entrance to the room closed.
UV causes thymine dimers. This is a strong bond between two or more consecutive thymine bases on same strand. This causes either no production of protein or the wrong sequence of amino acids thus organisms death. Great video!
These lamps are also used in water filter systems. Aquariums use them a lot. To kil of algie and the like and is part of a bigger filter system with active coal and good bacteria.
I had a bright idea to put the smallest one of these I could find (15W, I think) in the intake duct for my house's HVAC. The air was pretty fresh, and it knocked down the smell of "old people who chronically smoke" that my house came with, but it turned the air filter into dust. I imagine that if you had a screen to hold cooties and dust bunnies in front of the bulb instead of an organic paper filter, you could similarly turn all that stuff to dust too. Unfortunately, that furnace was pretty old, and I think the inner-coating of tobacco tar was the only thing holding it together and I had to replace it shortly after.
@@psirvent8 LOL, hell no... If I was on Mars, I would insist on an ozone and sulfuric acid air scrubber. That would turn pretty much anything that got sucked into the air duct into carbon dioxide, which could be absorbed into a water spray, that collects for direct application to a splendid greenhouse for remediation. Ozone is very unstable, and reverts back to diatomic oxygen on contact with water. This would leave an air-stream extremely clean, dust-free, and sterile to a degree that probably outperforms the filters on disease warfare laboratories near you. UV-C is dangerous. Ozone is dangerous, and so is the oxygen you breathe. When it benefits you, it's unlikely you even know it (swimming pools, drinking water, surgical instruments, water parks, sewage treatment, etc.). It's only when you naively wake the genie and demand something dumb that it fucks you up. If you go about it with careful deliberation, you can have years without any breathing nor skin allergies... Until your HVAC gets oxidized. I won't be needing any duct cleaning for a while though.

Yeah, I bought one. Love it. Makes my buddy's shop area smell much better... Funny to watch the bugs come up to it... They make it a few minutes... Then they go blind and crash into objects or just die mid-air and hit the floor
I have had this lamp for about 2 years and it works extremely well. I am an inveterate pipe smoker and my studio stinks to most people because pipe smoke penetrates deep into the walls. I leave this lamp on for an hour every 14 days and all the smell is gone and the room smells fresh again. Also, I then don't have to deal with pesky insects like fruit flies. I work with a timer and make sure I am far away when I let it start. Safety first :-) I also have miniature UVC/Ozone lamps for in storage cabinets. And also Ozone generator for fruits and vegetables.
These are quite common in the US - When you have forced-air heating and AC (As is common in US houses), the higher end systems often have a UV bacteria killing "light" in the intake airstream to augment HEPA filters and the like.
Robert Johnston another use in HVAC is in the drip pans, the Liebert HVAC systems in the datacenter I managed had such lamps to keep Legionella bacteria and algae from growing because they were running 24x7 and the room was humidity controlled so the pans were never dry.
We had a couple of bag filling machines in the dairy I worked at that each had 4 bulbs in them. The plastic film to make the milk pouches was threaded through the machine with the bulbs on each side of the transparent plastic film. They sterilized the plastic. I never noticed the ozone smell but in a dairy all you smell is milk most of the time.
Alan Hunter Small dairy with less than ten employees. Old school, started in the 40's. We had no fancy air circulation system. The doors and windows open in the summer is all we had.
Very interesting video. I have a very large one of those that is probably about 50 or more years old that I recovered from a University trash heap in New York State. Very effective at making ozone and sterilizing a large area. I only use it when I am checking for fluorescence of different materials.
that bulb is not a toy. they use the technology to sanitize hospitals, emergency and operating rooms, high-traffic areas as well as soil for growing mushroom, and in HVAC systems to control mold and fungi. I have one. I don't stay in the room while it's on, nor do I allow my pets in there. If you want to de-smell your bathroom, leave this in there for about 15 minutes, then air it out. This sanitizing bulb is a good thing - use it wisely or leave it alone.
Not wrong. I built a self contained air box for mine. Think a box with louvers the deflect light on one end and an air fiilter up against the fan. I tried to replicate modern HVAC systems that have UV-C bulbs permanently installed
You're brave holding that thing - I get antsy holding a 365nm blacklight, so you better believe when I turn on my 254nm lamp, I run out my room like a coward
I did an Amazon search for "Germicidal lamp" and came up with hundreds of many price ranges. I saw some which were very similar to yours. They all operated on 120 V .
As long as you didn't look at the blue directly it's safe, if not you might have intoxicated your eyes with UV-C, you can however fix it, pinch your nose so you can't breath out of it(remember to breath through your mouth or gills depending on what species you're), then stare at the blackest object you can find with all the lights blocked out, the darker it is and the blackest it is the better, and blink exactly 15 times, then un-pinch your nose and exhale all the air through it, go to another room before breathing or avoid getting that same air back in your lungs again, or do it in an exterior place(despite getting sufficient darkness outside might prove tricky), leave the room dark and alone for at least 15 minutes before anyone comes back in. To be extra safe you can repeat the process, but doing it more than 3 times it's absolutely redundant.
Didn’t even mention that these would be great for erasing EPROMs. I used to use toothbrush holders with these bulbs in them to erase my chips. Hehe. This would probably erase one in seconds. Hehe.
unaclocker, I suppose it will convert EEPROM's to write only memory after it turns the plastic housing into dust? Leave it on for a day and you will see what I mean.
Pyrex glass is borosilicate, uv lamps are quartz glass, regular bulbs are usually soda lime glass. You can also get significant uv from halogen lamps of all types (and older mercury lamps) if protective soda lime envelopes are removed.
Even some halogen bulbs that either come from slide projectors (24V 250W bi-pin for example), older dental curing lights and also some laser printers can put out enough UV to cause harm to the eyes and possibly skin too. That's because unlike halogen bulbs designed for general lighting which are made from doped quartz that blocks most of the UV rays, the aforementioned lamps are made from pure quartz glass and therefore transmit all the UV rays produced by the filament.
Last time I worked with uv c I had to put uv c protective glasses... a uv protective full face visor..special barrier cream.. opaque gloves.. clothes ..and under no circumstances exposed skin.
themaritimegirl Normal compact fluorescents use that coating to convert UV light to the visible spectrum. A clear compact fluorescent would just produce UV
Sybrand Botes, you've missed the entire point of themaritimegirl. To rephrase what she said ... She wished the Chinese made lamps that blocked the actual UV light and allowed the visible light to pass through and be seen. The spectrum given off by the mercury includes both visible and ultraviolet light. That blue glow you see is the visible light and it's completely harmless. But the ultraviolet light that's also given off is both invisible to us humans, and quite dangerous. Unfortunately, themaritimegirl's desire wouldn't work since a large part of the beauty of the UV lamp is the fluorescence given off by nearby surfaces due to the UV light.
John Cochran would it perhaps be possible to get a germicidal UV lamp and put a clear UV blocking cover over it? Maybe glass from a florescent lamp with the phosphor cleaned out.
Benargee, I don't see why it wouldn't be possible. But as I mentioned earlier, a major part of the beauty is the fluorescence nearby objects give off and that would be lacking if you filtered out the UV. And fluorescence is quite important even if you're not consciously aware of it. For instance, many laundry detergents have fluorescent compounds added to them that dye your clothing. Doing this causes whites to look "whiter" because the compounds emit blue light which counteracts the normally yellowish color that white clothing has.
When I was a little kid (early 'sixties), the clothes dryer my parents owned had a germicidal lamp in it. Strangely, it didn't go out when you opened the door. It should have. At least my parents knew what it was and told me never to look at it. Beyond seeing it just long enough to know it was blue, I didn't.
Key lime pie has an interesting story, supposedly beginning in the early 20th century when refrigeration was scarce. Sweetened condensed milk was used a lot in cooking, especially on fishing boats. Legend has it that the famous pie was created with what the Florida sponge fisherman had on hand: sweetened condensed milk, limes and crackers. Even at sea, there’s time for comfort food.

I'm 45 yrs old and ruined my eyes when I was just 17yrs old. I was helping out at the scrapyard where my Dad worked and came across a bunch of Metal Cylinders. I unscrewed them to find they contained FULLY Transparent Fluorescent Tubes. After wiring a ballast up and having tested 9 out of the 10 I found, I saw the Warning on the end of the tube whilst I was looking at the beautiful Ribbon shaped Bluey Purple light passing through the Tube!! It said, in Bright Red Letters..."UV-C. AVOID PROLONGED SKIN EXPOSURE. AVOID ANY EYE EXPOSURE. RETINAL DAMAGE WILL OCCUR"!!! Later that night I had a slight headache when I went to bed and at 3am, Pain like I have never known! I spent the next 2 weeks in the house recovering and HAD to wear dark sunglasses AT NIGHT, it was that bad. They're not toys. Don't piss about with them and stay safe around them. My eyesight was irreparably damaged and that diagnosis was from a top ophthalmologist through Private health care! "Never look at UV-C with remaining eye!"
i have been working around high power uvc lamps since i started work in 79 as a school leaver, we used them to cure printing inks. the early machines use to spill light all over the place and were not safe. they used very high voltage lamps that were powerful enough to set light to any material that got stuck inside the drying tunnel. we became very good at putting fires out, some were water cooled with the lamp inside a glass tube surrounded by flowing water and a cooling tower on the roof of the building. the modern ones are all enclosed and shielded low powered LED. i had two lamps similar to the one on show in a uvc pond filtration system. it worked very well.
I started saying oh no in my head and then aloud within about 3 sentences tbh.
Thanks for the warning. I am sorry you experienced eyesight damage. You only did what many of us would have done, not knowing the dangers.
I flashed myself by accident with one just a second and it scared me
Reminds me of the first time I saw someone welding, and it made this same beautiful blue light. I just couldn't stop watching because it was so beautiful.
And I payed for it with multiple days of sand eyes. Not sure about retina damage.
As a welder who has done stupid and burned his eyes, 'sand in the eyes' is the best description I know of.
i had done stupid things as a kid
its interesting how you can feel the light that strong
Our lot regularly misplace multi-tine fork/shovels to DC, or for variety go and spike the wrong 33KV cable (admittedly the latter also involves some singeing = > )
Good description, I've had welders eyes twice ,and once would have been enough , both times it came on at night and first time I dreamed I was working under a pickup and my eye's dribbled full of gravel , it woke me up , that was really bad since then I've heard of a lot of things you can do to stop the pain , such as an eye drop of milk and honey , but I had no clue about what to do at that time
It's not the sand in the eyes that's an issue. It's the fact that the sand doesn't leave for hours.

Every rest is agony, and so is every blink. It's a hell you do not escape
@@nathantschetter1264 I have had it a few times as well. I think it was clearly due to the position I was welding and the light coming in under my helmet? Though I have not welded for some years and if I ever do I will only weld with a hood cover.

I work at a plant nursery and one day i was changing an air filter on one of the a/c units. There was a similar bulb inside the ac unit to kill any unwanted bacteria. I only looked at the bulb for maybe 5 seconds from a distance of 2-3 feet. That evening I woke up in the middle of the night and it literally felt like I had sand in my eyes. I have never felt anything like that before or since, and it wasn't until watching this episode did I understand what had happened. Now I know, it was that d%^* light ! Thank You bigc !!
Is it was an industrial grade hvac bulb out was probably way stronger than the 20 watt bulb he's playing with here
Its generally a good idea to turn off any electrical device before messing with it, and reading an instruction. Most of devices even if are turned off, are still holding a charge.
They are actually becoming common on home HVAC units so beware if you're a DIYer. Should be in an area you won't commonly acess and most units you can just unplug.
I've heard of people going blind for a few days
ino your pain..experiencing it now
Oh noo! The memories, I found a bulb like this when i was a kid. Had no idea what it was. We set it up outside to attract insects. Little did we know we had been burning the skin on our eye balls for a couple of hours. Woke up the next day with my eyelids sealed shut! Was out of school for a couple of days.

The allure and beauty of the light reminds me of the Goiânia disaster in which a radiotherapy component from an abandoned hospital was stolen by people looking for scrap and dismantled, with the beautiful glowing blue and highly radioactive powder contained within removed. It was then passed around and handled by several people including a child and a woman who thought it would make for a nice eyeshadow. 4 people died and dozens more were exposed. Can't say I trust pretty glowing blue things.
Interesting
@Banter Maestro2 no it was Cesium 137 in the form of Cesium chloride

Yes he’s crazy and irresponsible to show this kind of behavior.
25watt globe, 15cm from the skin for 30 seconds will case sun burn in that location and skin will peel in a few days. I've done that to myself. The light does burn quickly. Distance is a factor.
It's not only the power. These lamps put out alot of Ultra deep UV light. That is very harmfull for skin and eyes. Ofcourse in combination with enough power but still, you do not need alot of power for ultra deep UV to damage cells

Theres a company selling a 4 bulb human sized UCV device that is meant to be wheeled from room to room in hospitals to sanitize them. However I believe they are supposed to run for 4 hours, also the cover on it pops off and doubles as a warning sign, because going into that room while one isnt exactly healthy, it also has sensors to yell at human who are near it while its on before turning off.
Vampires and Pillar men if you've got strong enough lights.
I've actually seen one of these used "properly".
I worked in a lab in Turkey and they had a room that had to be sterile for working with cultures. They had one of these lamps to sterilize the room when it wasn't in use, that you could turn on from the outside.
I think there was a rudimentary safety system in that you couldn't turn in on if the normal lights for the room were on (i.e. it was occupied) but scary nonetheless.
Oh nice

This reminds me of an incident when an OAP in our family managed to get a hold of these for his garage.. the reason being is he hated frosted bulbs and it was to replace the two clear halogen bulbs.. My ears pricked up as someone mentioned he was moaning about his new ‘energy saving’ lights not working and were ‘weird baby blue’ in colour.. sure as anything they were two germicidal bulbs in E27. No idea where he got them from.. he had been working under them for a good few days (using a bench light). Another ‘trigger’ for me when his son also said they set off his Transition glasses... that’s when I got involved... awhile ago but I do wonder how on Earth he managed to get a hold of them, as he was far from computer literate!

3:36 UV lamp tubes are made of fused quartz which allows the UV to pass through. Standard florescent tubes are made of glass that allows UV to pass but most of it is absorbed by the phosphor coating inside the tube to create visible light. Note any damage to the phosphor coating (this often happens at the ends of the tube) will allow UV leakage.
Was about to say the same thing. We have huge 50 Watt or so UV-C tubes at work for industrial water-sanitizers. It warns about the use of quartz glass on the package (besides a whole bunch of other warnings and logo's)
Nope, normal lamps usually have borosilicate glass because of its very low thermal expansion. Soda-lime-silica glass would break due to the high thermal stress.
Normal incandescent lamps (the now mostly banned kind) usually have a soda-lime-silica envelope and a lead-potash-silica stem (lower conductivity at high temperature avoids glass electrolysis in the pinch seal). Some larger discharge lamps and other specialty lamps have borosilicate outer envelopes. As far as I know, germicidal variants of normal fluorescent lamps use a soda-lime based glass formulated for low attenuation at the mercury 253.7 nm line, while higher arc loading industrial tubes use quartz envelopes. The easiest way to tell is to look at the glass-to-metal seal, soft glasses (soda lime, lead potash) often use dumet wires which appear red inside the glass, hard glasses (borosilicate) often use tungsten wires which appear brownish or yellowish, and quartz uses molybdenum foil seals.
_blocks any UV not absorbed by the phosphor_ Nope. But thanks for playing. They leak enough UV to bleach anything left under them for prolonged periods. (eg. MM fiber cables in a data room where the lights are always on.)
"Germicidal UVC lamps can be manufactured with one of two different types of glass - Quartz Glass or Soft Glass. Germicidal soft glass is a highly refined and pure type of soda lime glass, similar to that which is used to make visible light fluorescent lamps. ", "Transmission of UVC is approximately 9% lower than that of quartz lamps, leading to less initial UVC output.
Soft glass will not allow the transmission of UVC wavelengths below 200nm and therefore can not be used to produce ozone at 185nm." lightsources2015.wordpress.com/2015/04/02/tips-on-how-to-determine-if-quartz-or-soft-glass-germicidal-lamps-are-best-for-your-uvc-application/

As nobody seems to have mentioned it. I will also point out just how dangerous Ozone is, both itself and in reaction with other chemicals. So please ventilate the room well if using one of these. Also, for those people thinking of using this for sterilising rooms, remember that the UV-C will badly damage plastics, nylon, etc very rapidly. Painted surfaces, silk and other materials will also be badly affected. Don't use if you have cheaper man-made carpets.
meh if it burns your flesh that can distract you from the ozone danger you know
I just bought one of these and let me tell you, I could smell the ozone after only 5 seconds of operation. I just disinfected my bathroom for 5 minutes and the entire floor wreaked of ozone. The bathroom had no smell after the disinfection (except for the odor of ozone). Before the disinfection, the bathroom had a very moldy and dirty smell.
UPDATE: Due to COVID-19, I regularly use the lamp to sterilize my phone, keys, and other common items. Btw these lamps can be found all over eBay.
Link please?
Cleaning companies like servepro use ultraviolet ozone generators to kill mold and it neutralizes the burnt smell in houses after a fire.
Ozone is a disinfectant also, it degrades into O2 and O- which is an ionized free radical, it also forms OH- free radicals when dissolved in water which want to oxidize something badly and organic molecules are their favorite.

Regular fluorescent tubes have soda lime glass (not borosilicate) which is basically impermeable for any kind of ultraviolet, and these tubes, if properly made, have quartz glass. I say properly, because if the glass fluoresces at all, it's not pure quartz glass.
UV-C is greatly attenuated in air and it diminishes after several metres. It's absorbed namely by oxygen, and basically spent on creating ozone. Same process as in stratosphere.
At power of around 20 W skin exposure at 1 m should last for no longer than 30 seconds. Obviously, the closer one is and the more powerful the lamp is, the greater the skin damage. Of course, eyes are much more sensitive than the skin.
It's a poor way of direct sterilization because microbes in crevices are shaded and will survive. As a generator of ozone, it's ok. Having one installed in the airducts is great for keeping the air clean but *only* if the output air is reacted with a reducer to destroy the ozone. Ozone is an extremely power oxidizer, very corrosive for almost all organic molecules. You don't want to breathe that.

Thanks to the smell of Ozone nobody actually wants to deliberately inhale that. It's just as bad as chlorine smell.

Germicidal Tendencies
Back in the beginning of covid I ordered 2 uvc bulbs with ozone. Not sure if it ever really did anything for covid, but once the room is thoroughly ozoned up and you let it dissipate, the room smells super fresh. If you have mold or mildew problems, this will also kill that. But like he said, don't expose yourself, I put mine in a lamp without a shade and plugged it into a smart plug. Then I could leave the to room, close the door, and turn it on/off. Ozone does STINK and takes a hour or two to go away. Keep in mind it may damage other stuff in your room also, even paint.
new level of covid over-reaction just dropped
My Father was an Aeronautical Engineer that ended up becoming a part owner of an HVAC company, after the second world war II he came home and sold for this company involved only in commercial HVAC sales. I remember him bringing home a small commercial unit that would dispense ozone. When you switched the unit on the unit would pass a very large stream of ozone and make a large wind going through the unit even though there was no fan, the smell from the first second would make you almost ill. When my sister nearly lost her leg in a motorcycle accident he would turn the unit on while we left the home, when we returned he would turn off the breakers outside to turn the unit off, then hold his breath, go in the home and open the window to vent the home, that would kill 99.9 percent of the germs in the house, she never did get a secondary infection, lol..... Oh well, long story. fun times in the early 60's......
hii,
can you still locate that device that you were talking about that your dad purchased to kill germ in house when no body around ?
i am very much interested.

Sadly this unit has disappeared from my parent's things. Neither of my sisters has any ideas... The unit was about 12"x18"x8", it had a grill in both front and back with a couple of controls, you could adjust the strength of the unit from almost no ozone to a strong wind, the wire would glow from the current to a bright blue, I would love to look at it. at full force (all on) the wind was like you turned a good sized fan on! Dad didn't buy the unit, he owned a company that represented commercial HVAC companies, they gave him the unit. By the way, I'm 70yrs old.

It is essentially a welding arc in a glass tube. The sand in your eyes feeling is known as welders flash, and the burn pork smell of your skin is a common sign of arc burn from unprotected skin during welding.
Well at least the welding arc is bright enough to keep people not wearing protection to look at it for long enough to get a flash.
Also most people know the hazards and to look away if for example welders are welding in the street or other public places.
UVC germicidal bulbs on the other hand aren't nearly as bright as a welding arc and one could definitely look at their beautiful turquoise glow for hours and get permanent damage to their eyes afterwards without realizing it at first.
Much like the sun that is bright enough to keep people from looking at it long enough to get serious eye damage from the UV in itself. (Although it's "only" UVA and B as the UVC is blocked by the ozone layer in *most* parts of the world).
But there are blacklight tubes for parties that emit lots of UVA and almost no visible light and one could look at them long enough to harm their eyes without realizing it. (It's mostly eye strain and not much "sand" but still not good as it could lead to an increased risk of cataract and/or macular degeneration later in life).
Normally the "special glass” for these things is quartz, as in Quartz Halogen car headlights.
Quartz was also used in the little windows used to erase old style eproms.
Touching it with your fingers shortens the life of the quartz.
Frankly I would not have powered that thing up, unless I was in a different room, watching via video link!
Excellent. I was wondering if anyone was going to pick up on him handling the glass with his hands!
if you clean it off in a spirit before turning it on it will be fine. The oils left on it create uneven heating witch can shorten the life of the light due to micro fractures.
The quartz degradation only happens with lamps that run hot enough for skin oil residue to be soluble in it, which are usually halogen and certain specialist bare arc tube HID lamps. Lamps like this don't get anywhere near that hot. Also, these often use low/no iron glass as that is cheaper.
@@randacnam7321 I have a 250W Fc2 metal halide lamp, so the arc tube is enclosed, however the outer bulb still gets quite hot. In fact I wouldn't be surprised if this *outer* bulb was hotter than a halogen one.
Therefore I avoid touching it with my bare hands and clean it with isopropyl alcohol just in case.
But would it be as safe as you said in your previous comment to run it without cleaning it first ?
@@psirvent8 Those double ended halides are a special case as the outer envelope is also quartz.
I could see myself building some "air cleaner" station that filters dust out, takes humidity down and then passes the stream along one or two of these...
MazeFrame Exceptional idea. Probably quite useful to "filter out" odors. The glass on the bulbs would probably have to be cleaned frequently though.
Some high-end aquariums use a filtration system that includes a UV lamp ( enclosed ) to filter water as it is pumped through & kill algae & other water-borne parasites- harmless to the fish of course. Wouldn't recommend it for an air cleaner unless you only had it turned on for short periods- it gives off a strong bleach smell, hence why Clive said you need to leave the room while it's turned on, then leave the windows open to clear out the smell after you turn it off...
You're probably better off using a normal ozone generator (as seen in a recent Clive video) for that. the point of these lights is to sterilise surfaces, not just the air passing right over them.
SuicideNeil It's not because of the smell although ozone becomes annoying to smell after a while, but because of the UVC radiation which isn't too good for your skin or eyes.
Eryk- yeah, I did watch the video with the sound turned on- and the previous one he talked about too, but thank you all the same; sitting in a room that smells strongly of bleach wouldn't be any fun was my point. You'd only suffer skin/eye damage if the bulb was exposed- which it wouldn't be if it was enclosed inside of a filtration unit, as implied by mazeFrame.
Looks like a fun thing to have lit in your home when you are away, and a thief decides to break in.
Might make for nice gifts for porch pirates too!!

Hypothetically, if you have mosquitoes in the room, would it help convincing them to live shorter ? As in, not anymore when you enter the room 2h later ? Of course, at that point, all colored stuff in that room is also bleached...
I'm not sure how it would affect them. Whether they'd even try to fly to it.
Especially since it is the blue Spectrum and combined UVC it is almost instantly deadly to mosquitoes, larvae, beetles, flies pretty much everything. You Couldn't stop warning people about this bulb, kudos for that. This one's dangerous folks. 👌
Apparently the ozone will kill most insects after some time. Mosquitoes may fly to it because of the emmissions above the UVC range.
I don’t think that It will bleach things. Atleast not a lot. I haven’t noticed it yet with my weaker UV lamps. I need to get one of these, But I’m on 110V I hope I can use it on 110V.

It was very nerve-wracking to see you plug it in lol. Felt like watching someone go into Chernobyl without a hazmat suit
so what you're saying is "if you want to feel like a welder, without the paycheck or self fulfilment, buy a uv-c lamp and stare at it".
The UV can be reduced by reducing the current through the tube. But the glass still does emit the UV, just in less intensity. If you want a lamp that color, but not so dangerous, you can have one made at a neon sign shop from soda glass. I have a few of them. They are very pretty but don't emit much light.

No, UV Lightning!
We’ve got like these 6ft tall UV lights at the school district I work at. Hospital grade and we use them to kill germs and any illnesses. They work fantastically but you need to be really careful if the teachers have plants or animals in their rooms. A few years ago a teacher had 2 turtles in her room. Light was on for 3 hours and killed both turtles. So ya. This light is potent.
In a school? Bizarre. Seems like a recipe for disaster.
Hopefully she doesn't have any children or they might be set up for a similar neglectful fate.
That was just plain stupid!
I've used these lamps in microbiology labs before and they really drilled into us to not turn the lamps on while we are in the room.

Ordered this bad bug just for that.
Me too, I have a wearable necklace unit too!

just be careful with these things. A few minutes is enough for eye irritation for the next few days.
Also for the ozone, if you can smell it, it will irritate your lungs, what you definetly don't want in a time of the corona pandemic (you will be infected easier). BTW I use it in a cardbord box to sterilize everything I buy at the store, also for my clothes, which I wear on the street.
I don't know how effective is the ozone for killing viruses. Anyone an idea about that?
Péter Szőllősi I read about the ozone and it is very effective but the effects are erratic. Good against germs and will also cancel organic smells but chemicals like glue used in carpets is just turned into something else which is probably just as toxic. So don’t rely on ozone on chemicals.

Won't matter (to the lamp). It does not get hot like a holigen or tungsten lamp.
@@raymondbergeron3384 it lessen the effectivity because your grease reflect the light.
You can actually find these in garden/hardware stores, they are commonly used in garden pond sterilizers.
These lamps are also really good at wiping UVROM's (EPROM) in a matter of seconds.
@@jamestreese4 Erm, there are legit reasons to want to wipe a UVROM/EPROM - for example if you do DIY electronics and want to repurpose one you harvested from a donor board for some project.
Quartz based glass passes UV, they use bulbs like that for high intensity photo chromatography when processing certain biologic samples. There will be a broad spectrum tungsten lamp and a UV lamp and a precision controlled prism that will pass certain wavelengths at precision angles, and a photo detector to measure the transmissivity of the sample. The sample holders have to be quartz to measure any UV.
I'm not sure why I couldn't think of the word quartz while I was making the video.
Brand-Tech makes plastic, disposable, UV transparent (down to about 230nm) cuvettes which are about $1 each. www.brandtech.com/wp-content/uploads/cuvettegraph.pdf
Thomas Burkholder cuvette, that's the word I couldn't remember.
Actually the monochromators are usually based on diffraction gratings rather than prisms. And for UV spectroscopy or UV detectors for HPLC etc they usually use some interesting (aka expensive) types of lamps, e.g. deuterium arc lamps.
David Robertson those diffraction gratings are a BITCH to calibrate, I remember that much. It's been like 10 years since I've touched that kind of equipment. HPLC pistons I also remember being expensive as they were typically man-made Ruby to handle the pressure, and the little windows were man-made sapphire. I'm glad I don't work in that field anymore.

Hospitals have a sterilization light that they wheel into rooms that had patients with particularly nasty infections. Someone posted a picture on Reddit where all of the cabinets in the room were open and the garbage cans were on their side facing the light.

therealnightwriter no they are not. However, the patient might die from vitamin c toxicity.
Interesting how they emphasise several times that it's "natural" uv-light.
It's not sterilization, it sanitization. It brings the level of viable germs to low values, but it will not kill every one of them, as well as their possible spores.
if this was effective, ethylene oxide and plasma and gamma rays would not have to be used, and they are used.

I'm thinking more like cancer lamp.
The UVC lamps are common in marine and freshwater aquaristic. I'm using it in my nano-reefs all the time. But they are hidden in black cases obviously.
In my younger days I worked in blown film plastic factories and we used a device that put an "arc" across the plastic film to create small pits so when they printed the film the ink had somewhere to pool and set (not technically correct but good enough for my tale of woe). If the film wasn't treated then the dry ink would just peel off when sellotape was applied and removed. One night the pipe that exhausted the ozone to the outside broke. It was a large factory about 75 metres long, 25 metres wide and 15 to 20 metres high. There were two rollup doors that extended more than half way to the top of the building and there was a slight airflow. We had both of these doors open and all three of us (it was on the night shift so minimal staff) got ozone poisoning. It was like the hangover from hell; *VERY* unpleasant and it took a few hours after finishing work for the "hangover" to subside!
I later became a Network Engineer and made myself a tad unpopular with my employers when I would point out the crisp smell coming from the high volume printers and especially photocopiers was a poisonous gas and proper ventilation of the photocopy rooms was required. Also suggested that the high volume A4 printers should not be sitting next to someones desk but rather a few feet (a metre) away. I really came to hate the smell after my nightmare in the factory.

I suspect the metal cylinders aren't getters, but "givers": sintered lumps of mercury amalgam, that give off mercury when heated. They're a simple and convenient way to deliver a specific amount of mercury, without having to handle actual liquid mercury. It was interesting watching the mercury propagate through the tube when you had it lit too: the tubing nearest the cathodes/givers had the bright blue mercury vapor look to it, while the tubing farther away showed the paler discharge of just the carrier gas (argon?). I made a tube once with neon and mercury and when I first fired it up, it light the brilliant red of a neon discharge, and I could watch the blue move through the tube and take over as the mercury vaporized. I wish I had filmed it.
They may indeed be a mercury amalgam for controlled dosing. I have a neon mercury tube with a dip in the middle to trap the migrating mercury when the tube is run on DC. It takes a long time, but the residual mercury at the electrodes finally migrates away and the tube then lights more or less half and half red/blue.
"Anti-acarien" presumably means "mite-killing", from "acaria", the scientific name for the mite group.
It does seem to imply dust mite ability. Not sure how effective it would be.
Anti-Acarien is a very common term in French. The insect that we call "mite" in French, is called moth in English.
It's an ultraviolet light source. This lamp produces hard ultraviolet light. Electric arc welding does the same thing.

The UV box I use for curing photopolymer is basically just a naked 175W mercury vapor arc tube in a box with ducted exhaust. It can turn white pvc brown in a few minutes, and the light leaking into the duct makes the hose brittle.
Cataracts are a thing. Had to have mine out at age 52. I spent too much time without eye protection around black lights as a youngster also, we didn't know about UV protection in the '70s.

These lamps are also used in water filter systems. Aquariums use them a lot. To kil of algie and the like and is part of a bigger filter system with active coal and good bacteria.
This is a very good thing (maybe) if it is used properly and kept in a secure way that it won’t be accidentally used when the room is occupied.
I had a bright idea to put the smallest one of these I could find (15W, I think) in the intake duct for my house's HVAC. The air was pretty fresh, and it knocked down the smell of "old people who chronically smoke" that my house came with, but it turned the air filter into dust. I imagine that if you had a screen to hold cooties and dust bunnies in front of the bulb instead of an organic paper filter, you could similarly turn all that stuff to dust too. Unfortunately, that furnace was pretty old, and I think the inner-coating of tobacco tar was the only thing holding it together and I had to replace it shortly after.
Now you know to avoid the ozone generating ones don't you ?
@@psirvent8 LOL, hell no... If I was on Mars, I would insist on an ozone and sulfuric acid air scrubber. That would turn pretty much anything that got sucked into the air duct into carbon dioxide, which could be absorbed into a water spray, that collects for direct application to a splendid greenhouse for remediation.
Ozone is very unstable, and reverts back to diatomic oxygen on contact with water. This would leave an air-stream extremely clean, dust-free, and sterile to a degree that probably outperforms the filters on disease warfare laboratories near you. UV-C is dangerous. Ozone is dangerous, and so is the oxygen you breathe. When it benefits you, it's unlikely you even know it (swimming pools, drinking water, surgical instruments, water parks, sewage treatment, etc.).
It's only when you naively wake the genie and demand something dumb that it fucks you up. If you go about it with careful deliberation, you can have years without any breathing nor skin allergies... Until your HVAC gets oxidized. I won't be needing any duct cleaning for a while though.

I have had this lamp for about 2 years and it works extremely well. I am an inveterate pipe smoker and my studio stinks to most people because pipe smoke penetrates deep into the walls. I leave this lamp on for an hour every 14 days and all the smell is gone and the room smells fresh again. Also, I then don't have to deal with pesky insects like fruit flies. I work with a timer and make sure I am far away when I let it start. Safety first :-) I also have miniature UVC/Ozone lamps for in storage cabinets. And also Ozone generator for fruits and vegetables.
You dumbass. Ozone doesn't "freshen" anything. It actively deadens your nose smell receptors, and can be permanent. It also damages your lungs.
These are quite common in the US - When you have forced-air heating and AC (As is common in US houses), the higher end systems often have a UV bacteria killing "light" in the intake airstream to augment HEPA filters and the like.
Robert Johnston another use in HVAC is in the drip pans, the Liebert HVAC systems in the datacenter I managed had such lamps to keep Legionella bacteria and algae from growing because they were running 24x7 and the room was humidity controlled so the pans were never dry.
Also in pools and hot tubs now for sterilization of the water to help take take the place of some of the chemicals.

CDP135Z mabye the ozone?
We had a couple of bag filling machines in the dairy I worked at that each had 4 bulbs in them. The plastic film to make the milk pouches was threaded through the machine with the bulbs on each side of the transparent plastic film. They sterilized the plastic.

Not Cow Shit?
Squishy Zoran not in the dairy itself. That would be at the farms.

Very interesting video. I have a very large one of those that is probably about 50 or more years old that I recovered from a University trash heap in New York State. Very effective at making ozone and sterilizing a large area. I only use it when I am checking for fluorescence of different materials.
that bulb is not a toy. they use the technology to sanitize hospitals, emergency and operating rooms, high-traffic areas as well as soil for growing mushroom, and in HVAC systems to control mold and fungi. I have one. I don't stay in the room while it's on, nor do I allow my pets in there. If you want to de-smell your bathroom, leave this in there for about 15 minutes, then air it out. This sanitizing bulb is a good thing - use it wisely or leave it alone.

If your monitor is led then no. Led = Light Essence of Death. Meaning it can eventually kill you
As long as you didn't look at the blue directly it's safe, if not you might have intoxicated your eyes with UV-C, you can however fix it, pinch your nose so you can't breath out of it(remember to breath through your mouth or gills depending on what species you're), then stare at the blackest object you can find with all the lights blocked out, the darker it is and the blackest it is the better, and blink exactly 15 times, then un-pinch your nose and exhale all the air through it, go to another room before breathing or avoid getting that same air back in your lungs again, or do it in an exterior place(despite getting sufficient darkness outside might prove tricky), leave the room dark and alone for at least 15 minutes before anyone comes back in. To be extra safe you can repeat the process, but doing it more than 3 times it's absolutely redundant.
Didn’t even mention that these would be great for erasing EPROMs. I used to use toothbrush holders with these bulbs in them to erase my chips. Hehe. This would probably erase one in seconds. Hehe.
unaclocker and the uv cured plastics and resins might work well with this too.
unaclocker what are eproms
erasable programmable ROM (read only memory)
unaclocker, I suppose it will convert EEPROM's to write only memory after it turns the plastic housing into dust? Leave it on for a day and you will see what I mean.
People still use UV erasable EPROM? I thought everything just used flash memory now.
Pyrex glass is borosilicate, uv lamps are quartz glass, regular bulbs are usually soda lime glass. You can also get significant uv from halogen lamps of all types (and older mercury lamps) if protective soda lime envelopes are removed.
Even some halogen bulbs that either come from slide projectors (24V 250W bi-pin for example), older dental curing lights and also some laser printers can put out enough UV to cause harm to the eyes and possibly skin too.
That's because unlike halogen bulbs designed for general lighting which are made from doped quartz that blocks most of the UV rays, the aforementioned lamps are made from pure quartz glass and therefore transmit all the UV rays produced by the filament.

It's a shame the Chinese don't make clear fluorescent lamps out of regular glass for decorative use.
Because the public will likely get confused and would probably use one of these germicidal lamps by mistake
themaritimegirl Normal compact fluorescents use that coating to convert UV light to the visible spectrum. A clear compact fluorescent would just produce UV
Sybrand Botes, you've missed the entire point of themaritimegirl. To rephrase what she said ...
She wished the Chinese made lamps that blocked the actual UV light and allowed the visible light to pass through and be seen.
The spectrum given off by the mercury includes both visible and ultraviolet light. That blue glow you see is the visible light and it's completely harmless. But the ultraviolet light that's also given off is both invisible to us humans, and quite dangerous. Unfortunately, themaritimegirl's desire wouldn't work since a large part of the beauty of the UV lamp is the fluorescence given off by nearby surfaces due to the UV light.
John Cochran would it perhaps be possible to get a germicidal UV lamp and put a clear UV blocking cover over it? Maybe glass from a florescent lamp with the phosphor cleaned out.
Benargee, I don't see why it wouldn't be possible. But as I mentioned earlier, a major part of the beauty is the fluorescence nearby objects give off and that would be lacking if you filtered out the UV. And fluorescence is quite important even if you're not consciously aware of it. For instance, many laundry detergents have fluorescent compounds added to them that dye your clothing. Doing this causes whites to look "whiter" because the compounds emit blue light which counteracts the normally yellowish color that white clothing has.

Key lime pie has an interesting story, supposedly beginning in the early 20th century when refrigeration was scarce. Sweetened condensed milk was used a lot in cooking, especially on fishing boats.
