Most stuff on the market is 280nm or above.
Sodium Hyperchlorite breaks down to salt water in about 20 sec.
Do your research????? This WAS our research. C’mon man!
QuantaDose is a quick and easy UVC light test
So you are saying that a knife isn’t safe since you can cut yourself, children can grab it and hurt someone or themselves, and therefore one day knives will be safe enough for humans to safely handle? Bwahahaha 🤣🤣🤣. If you are unable to handle a knife, then don’t use it in the manner it is meant to be used. Same principle applies here, UV‑C needs to be understood on how to use its light, contain it, how to apply it to objects without the detrimental effects it can have on living cells that should not be exposed. Some adults may not be smart enough for a knife, or UV‑C light, but a lot of us know how to safely use them, I wish humanity would just “grow up” and get on with it and take the time to learn and work with knowledge and wisdom instead of waiting for someone else to certify and make things dumb-proof. The law of lowest common denominator is not a good prospect in a fight against an invisible virus… 😆😆😆
Our society will be creating a new Superman or Superwoman virus because of all this new technology the virus or the bacterias will start evolving if you know what I mean. So don’t be surprised when you hear one day on the news that there is a super super duper virus out.
Oh wait wait we are already hearing it from California Gavin Newsome is saying something like that.
What this video forgot to mention is that it is very easy to test any UV‑C lamp or wand yourself to see if they are producing light in the proper germicidal range. You can purchase UV‑C testing cards for around $13 each and UV‑C testing meters for around $100 on-line, both of which will tell you if the product you have purchased is producing light in the 253.7nm UV germicidal range. The point that they made about many of the LED-based products being junk and not being germicidal at all is true. There are many good videos on YouTube that show these devices being tested. Just because an LED produces blue light does not mean it is germicidal at all. Make sure that if you buy LED-based UV‑C sterilizing lamps or devices you are doing it from a company that is known to produce reputable, effective products. Also, although FAR-UV‑C lights that operate in the 222nm range (believed but not yet formally certified as safe for use around people, plants and pets) are available but are not yet commercially viable due to their high cost. They can be purchased today, but are priced in the $1,500 to $1,800 price range. Once they are eventually certified for commercial and home use, then competition will certainly drive their price points down to a far more affordable range. This was anticipated to happen by the end of 2020, but we are still waiting for this to occur. Until FAR-UV‑C becomes available, please make sure that if you use UV‑C sterilizing lamps or hand-held wands that you wear the proper UV protective eyewear AND be sure that ALL of your skin is covered at all times. Not that the best way to use these lamps is to purchase ones that can be activated and de-activated by remote control so you don’t even have to be in the same room with them to turn them on or off.
PARVASENS! Is the answer!
This is great info
It is good thing that most of those hand wands does not have UV- C dioeds. Bcs they are not cheap. So usually there are some of those “party” UV diodes.. no no damage will come.. but also no bacteria/virus killing
Uvc light smell really bad. You have to ventilate room after use.
does UV light create harmful ozone
This is wrong, it’s not the whole picture.
First is proper wave length, 253.7nm is common and effective. Next is nJ output, which you can understand as heat which needs to be at least 22,000nJ and then it’s about duration of exposure which really needs to be greater than 1 second or the longer the more effective.
Wavelength x intensity x duration is the correct formula or
253.7nm x >22,000nj x > 1s
Is what is required to kill covid-19.
No hand wand accomplishes this. Hand wands are a scam.
Columbia University has been doing research on 222nm for years.
can you make a video of UVC inflight treatement of Honeywell company !!
What is the standard ppe to wear when operating the machine !!!
Wait a second here, a quartz halogen emits ultra violet light, when it does not have a glass cover on it! Those 500W halogen tubes produce UV light if they don’t have a glass front on the fixture. Don’t believe me sit in front of a 500W halogen light fixture with the glass cover missing for an hour, you will get a sunburn. I had to edit this to include, “Do not look too long at such a light bulb, it can cause eye damage!”
lol. UVC “safe”.
It’s not safe. If it’s safe, it doesn’t disinfect.
But the basics of it is if you can see a cool blue ray inside the tube, it’s UVC. If it’s the case, don’t look at it directly or expose your skin to it (looking at it for too long will basically burn the surface of your eyes (giving you a feeling of dry/irritated eyes), which fixes itself. Exposing skin to it will give off a burnt/cooking smell. Breathing the ozone it makes is also dangerous. Ozone may smell good, but it’s toxic).
.…. but it does the job in killing microorganisms.
I plan to use a UVC lamp for my enclosed room to disinfect as I work in the hospital setting that its also in the Hospital’s employee wing. The UVC Lamp emits ozone which for me benefits me as I am hyper allergic and hypersensitive to air changes. I vent the room for a good 30 minutes before entering and question whether that’s enough or should I wear a PPE first that is for UVC exposure. Or should I just aerate the room for longer?
a ton of fakes on Amazon. I have a UVC tester to make sure the light is real and at the correct wavelength.
Thank you. And, a uvc lamp ad comes right after finishing this video.
I bought Xiaomi Five, and I can be away from the room I disinfect, but when I get back, it smells uncomfortable 🤔
Im a doctor and work with covid and use a UVC box and a UVC lamp to disinfect my rooms and equipment. There are alot of fake UVC thing floating arond. Be carful so you buy the legit thing.
Stop that stupid music, can’t hear your words clearly
I work with real, lab tested, medical grade UV‑C devices. The way a lot of these videos are made seem to exaggerate the actual risks and dangers of UV‑C light. Comments also show that not many people understand this technology. To make it short, UV‑C devices are fine if they do not expose direct light or direct contact to your skin. Reflective light is fine, it gets exponentially less dangerous the further away it is from the source. Not to encourage this behavior, but just FYI I have ‘briefly’ looked directly at the UV‑C lamps, not up close, many times and it’s been fine. The way these warnings are written make it seem as if you peak at it for a second, your eyeballs would burn to ashes. Keep in mind all those warnings seem very scary but nearly any manual of devices will have statements that seem extremely scary but they’re just required to say it even if the chances/risks are near 0% to cover liability issues. Absolutely should take precautions and risks are risks but keep in mind even a microwave that one might use everyday can sound just as scary as a UV‑C device. Make sure to get a device that has been lab tested and proven to kill germs and has safety features such as if you open it, lamp should never turn on while it’s open and the source/lamp should never be exposed while in use. As long as it’s in a well made enclosure, you should be fine. Now to test if it’s a real UV‑C lamp, you can get a UV meter that specifically tests for UV strength. If it’s in 253nm range then it is legit. Lamps that have no enclosures are either fakes or are dangerous and so I wouldn’t even get one of those ‘UVC wands’ if your goal is to kill germs. Devices you are purchasing for use should not require you to wear any PPE, unless you are working on troubleshooting it or something which is not recommended unless you really know what you’re doing.
I know below 260 nm is junk and that is what you will find on Amazon. The kill zone is 260 to 270 with 268 being optimal. HOWEVER. a 260 will need a longer burn time. NO ONE should be in the space being disinfected. Much like our kids SHOULD NOT drink house paint stored in our garages. THEY ARE SAFE. IF used properly and vented properly.
Water heaters are safe. DO NOT STICK YOUR HEAD IN ONE!!!!! DO NOT TREAT A UVC LIGHT LIKE A LIGHT. AND DO NOT LOOK AT YOUR GRANDPA’S TORCH WHEN HE IS WELDING!!! UVC HAS BEEN USED FOREVER IN HOSPITALS. HUMANS ARE VERY IRRESPONSIBLE AND THEY HEAR THE WORD “LIGHT” and that is when accidents happen. You have to have a long extension chord and power it on when you are SAFE around a corner. THE UVC LIGHTS ARE COMPLETELY SAFE. IT IS THE HUMANS THAT ARE STUPID. If we could get past that we could have a device that will do what 10000 bottles of lysol can do. (and yes …without a ladder)
260 nm to 270 nm is the kill range for viruses 265 at 30mm will kill in 030 seconds but that is a LONG way from several feet needed to clean surfaces in an area. The good news is increasing the exposure time WILL get it all. HOWEVER. UVC light does not BEND, so you are talking about air, major surfaces etc. I suspect a 360 plan would include bleach foggers, uvc 260 to 270 (with sufficient power) and room temperature manipulation like they do in hotels for bed bug infestations which are more common than you think.
2:26 does anybody knew the type and brand of this handheld sterilizer please??? I wanna know..
I use an ozone generator in my house. It’s in-line with the air intake of my HVAC thus my air handler pulls the ozone into the system and spreads it throughout the house through the ducting. I’ve been doing this for decades. How do I know if I’m causing damage?
Thanks a lot, this is pretty helpful
What is the difference between UV-black light and UVc
Can UVc kill fungus ??
I specifically want a directional LED bulb to decontaminate a dug well on my property. Watching this I find it appalling that so many people are afraid of a cold that they will bombard themselfs with light that could cause burns, eye damage, and cancer.
uvc is beneficial to plants, not humans…
👍👍👍
So, how to know if a UVC device will be safe and effective? Which device makes the most sense? This video gave no answers.…
Disappointed that you didn’t mention a UV meter or dosimeter cards. Also, you definition of UVC does not match what Wikipedia says (Wikipedia says it is 100–280 nm not 200–280 nm).
Who wants to wave a UVC lamp around or hold a UVC meter while it and anyone nearby gets hit by UVC? Not me. I want the lamp to come on via a timer, or be turned on from outside of the room. I also don’t want to have time the process. I want to blast the room, and then walk into a UVC free room and check the pieces of card or paper that I stuck on every surface to see what color they are, and move the lamp to different place, direction, and/or power, and blast the room again, perhaps for a bit longer or for a shorter time, and keep doing this until every part of the room that I want “cooked” is cooked, and verifiably so.
I guess I might want to turn of the lamp and move the card slightly to avoid a UVC shadow that creates a sort of Achilles heel.
Perhaps there’s no need for special dosimetric cards if that’s the right term. Maybe one could use unripe fruit instead? Or perhaps pieces of ordinary colored paper or cloth or tape or stickers that happen to be strongly bleached by UVC in the amount that sterilizes a surface without damaging it.
By the way, beware of accidentally bleaching exposed parts of clothes or furniture and other stuff. If sunlight can do it, I think UVC lamp could. Does anyone know whether UVC lamps bleach cloth, book covers et cetera?
using UVC machine to sterilize C pap machine. Manual says it is good on all surfaces. My constant pressure air machine uses tubing how do I make sure the tubing THE inside is sterilized.
UVC Cool
I’m curious if you could provide any information about this device?
Airstream UV Air purifier 210 — High intensity UVC / UVV lamp
Please be very aware that reflected UV light from shiny surfaces can damage skin and eyes.
Classic example welders working inside round stainless steel tanks wear protection covering the back of the neck.
A movement-detector accessory that immediately switches off the power or the mains electricity supply would be an obvious solution for most of the human/pet exposure problems. There are obviously many motion detector devices out there that switch things on — but what about any that switch things off? Anything on Amazon at all?

ALL uv‑c lights are dangerous. lol. Ionizing radiation so it creates ozone and can burn you and give you welders burn in the eyes.
Update 2024-Ed Neister, a physicist in NH discovered the power of 222 nm, Far-UV for disinfection in 1998. Long before anyone else researched Far-UV. There are dozens of studies that have proven the efficacy and safety of Far-UV. You don’t have the luxury of waiting for an air exchange to shield the other people from the aerosolized viral particles if one person in the room is exhaling viral particles. The only technology that doesn’t use air exchanges to destroy airborne viruses is 222nm Far-UV.
Safe for occupied spaces.
If anyone is intetested, UVD Robots are the best commercial UVC devices on the market
Capital gain . Follow the money the Americans dynasties still need consumer reports that have been tested for human safety.
IS consumer reports are essential. FDA Approved FTC and FCC approvals were at least trying to save human lives.
