That ozone created by the UV-C light is no joke. I did some testing on a similar bulb purchased off Ebay when the global Covid-19 fears were peaking. I made a box for use with UV-C light to sterilize N95 masks for personal reuse (my wife and I work for a hospital that could not procure enough N95 masks for one-time use). I got scammed off a couple Ebay LED units that claimed to emit UV-C that didn't (using the banana method, then the use of UV-C sensitive cards). I didn't have much hopes that the glass bulb was actually emitting UV-C but when I opened the door to the vacant room being used for the test, I was hit by a smell of what I can best describe as burning wires. I ignored it figuring it was some oils cooking off from the unit as it just ran for 30 minutes. I then noticed the banana was dark and the UV-C card was indicating intense exposure, going from white to black. Then my nose started pouring blood, sending me tf out of the room. I've read that, in high enough concentrations, nose bleeds and respiratory distress are the first symptoms of significant ozone exposure. I was fine, but those concentrations must have been insane as I was only in the room for 15-20 seconds before the nosebleed. It was likely all for not... we both contracted Covid. Twice.
Great video! The UV-C tubes also use a special fused quartz glass, which unlike say borosilicate glass is essentially 100% pure silicon dioxide. This ensures that the UVC can pass through it as the additives added to most other types of glass(most transparent material types) actually blocks UVC. You can also get UVC bulbs/tubes that have their fused quartz doped with a small amount of titanium dioxide - the titanium dioxide allows the 254nm UVC wavelength through, but blocks the 180nm UV wavelength which generates the ozone.
@@WhatTheHeckManNp! And yeah, that makes sense. There are many applications where one might want the 254nm wavelength on its own without any ozone generation. When ordering new UVC tubes - its always good to know whether you are ordering ozone generating tubes or non ozone generating tubes specific to the type of application you want. It's good to know that you now know what to look for when ordering new tubes 🙂 You can also get 280nm UVC LEDs for sterilisation too, but those only emit 280nm specifically - hence no Ozone. I probably prefer the old fashioned mercury vapour discharge lights over LEDs though, since due to the ozone generation and slightly shorter 254nm wavelength(~260nm is best at splitting DNA) the discharge tubes I feel are slightly more effective than the LEDs at sterilisation...at the slight cost of safety ofc... There are also these new 222nm UVC excimer lamps that are *SUPER* expensive - they apparently are safer to be around as the moisture on your eyes and the dead skin layer on your skin block that 222nm light...but I would still be a bit skeptical of the safety since it is still shortwave UV light we are dealing with in those 😅
@@WhatTheHeckMan Also - Would it be possible to try the banana experiment with a UVC tube that doesn't generate the ozone vs the one you tried in this video as a control? I have seen these types of experiments a bunch, but I do wonder how much the ozone generation contributes to the banana browning up? Not many RUclips experiments really say what type of UVC tubes they use...
I have one ! It does have a smell but I really don't think it smells that horrible. It just smells a different clean . I use mine around the house every week!
They were standard equipment for barbers too in order to sterilise the combs shavers etc. I have a UV-C flouro tube here for erasing EPROMs - hasn't been used in ages (like last millennium) but always used with great care as these will damage your eyes and accelerate bad things like melanomas etc
I like it too because if you live in the south where spiders creep in and creepy crawlers it kills them too. So if you enjoy doors and windows open and misquitos get in or ants in the kitchen bye bye problem!! ❤
Based on your own preference. It says you can use it every day if you want. I typically just put it in a room each time I leave the house for a few hours, so when we get back, it's clear to re-enter the room. Thanks for watching 👀
Absolutely an oversight on my part. Definitely should have shown that to compare. The control plant is still flourishing but I know word only goes so far, visual is needed here.
I have a gaming setup in my room will it will fully disinfect my desk and monitor and everything in the room just by having that on or is just for the room air and stuff If it cleans every item in the room i will for sure buy this
Nice testing video. The ozone itself is evidence that the lamp is emitting real UVC. The lamp doesn't emit the ozone, but rather the lamp emits the light and the light tears apart the O2 in the air, and as the free oxygen is rattling around some of it recombines with another O2 to for O3 (aka ozone). It actually IS rather unhealthful to breathe. It's not simply that O2 is being reduced, but the ozone itself is damaging to life. In fact, it's my understanding that sometimes ozone alone is used for sanitization (although I've only heard that). Again, nice video. It's important to actually TEST and use items to know if they work! I use UVC on an ongoing basis to sterilize stuff coming into my house. I picked up the habit during early covid and haven't dropped it. It seems to extend the refrigerator life of a lot of our produce doing that, and it's nice to think that random people's sneezes are getting sterilized off our foods before they even enter the house.
I always learn a TON from comments people leave on my videos too. I think a lot of the time people think with our channels, the learning flows in one direction (from us hosts out to the viewers), but the viewers often have a LOT of expertise about video topics - and they're even sometimes polite about it! ;) Again, great video. I noticed it was your 365th (one for every day for a year) @@WhatTheHeckMan
All you did was give the banana a tan. UV-C is the most dangerous range of UV light. UV-C can't pass through the typical glass and is absorbed by glass, plastics, and clothes. UV-C light is used as an effective air purifier in HVAC systems, hot tubs and home water supply systems.
i have one, the advertisment I watched said it kills bed bugs, dust mites, mold spores, etc. I used mine once in my room where nothing alive was. I still have it and may use it again but am not in a hurry
Any thoughts for the highest power germacide UVC lamp for sterilizing/disinfecting? COOSPIDER U/V/C Light Lamp 185nm with 253.7nm Bulb 5ft Cord and Plug 110V (6W Ozone Lamp) ? COOSPIDER UV Light Bulb, 36 Watts (E26 110V CTUV-36 with Ozone)? G6 Wellness UVC CFL 25W? BTW, I understand UV LEDs are more powerful than UV CFL Lamps, yet most of the UVC products use CFL not LEDs.. At first I was thinking of using one of those nail polish curing devices.. like the 320W SUN X21 (72 Leds) but they only come in 365-405nm... they don't seem to come in the shorter wavelength (higher frequency) side of the spectrum.. i.e. UV-C (180-280nm).. not UVB (280-315nm) or UVA (315-400nm).
Could you try on a container with ants in it? That way we could really know if it kills bugs.

Why kill large objects with more mass vs tiny air floating organisms?
That’s why the ozone layer is so important. Majority of UV-C is blocked by it. Allowing life as we know it to flourish.
Thanks for watching 👀
Interesting to know!😮

Thanks for watching. I did not know that information 👍 I have the UV -C light in my duct work also but it doesn't create the ozone at all.

I will take a look and see if it's possible to remove mine from the ac duct in a safe manor to try it out.

what is the purpose for using it in your house ?
They were standard equipment for barbers too in order to sterilise the combs shavers etc. I have a UV-C flouro tube here for erasing EPROMs - hasn't been used in ages (like last millennium) but always used with great care as these will damage your eyes and accelerate bad things like melanomas etc
Thanks for watching! I definitely always follow the instructions 👍
I have never heard of these things. Pretty cool
I didn't know they had them for houses till recently. But so far it seems to work I guess haha
bananna got a sun burn
Plant sacrifice video in progress.
This kind of reminds me of the foot x-ray machines shoe stores had in the 1950s. Nobody had a clue as to the long term effects.
I like it too because if you live in the south where spiders creep in and creepy crawlers it kills them too. So if you enjoy doors and windows open and misquitos get in or ants in the kitchen bye bye problem!! ❤
How often is it suggested to use it? Weekly? Monthly?
Based on your own preference. It says you can use it every day if you want. I typically just put it in a room each time I leave the house for a few hours, so when we get back, it's clear to re-enter the room. Thanks for watching 👀
Curious as to why you did not show your control plant.
Absolutely an oversight on my part. Definitely should have shown that to compare. The control plant is still flourishing but I know word only goes so far, visual is needed here.
Just put tape over even your mouth and see it affects your skin. That is so ridiculous.
Will it kill dust mites and bed bugs?
It does say that it will kill both.
Yes
Far-UVC you can be in the room while working. You have to look at the NM 222 and under are considered far.
Bullshit channel 😒 uv lights home is really crazy 🤪 not a real benefit 😒
That's crazy that it does that!! 😳
Wouldn't want to be in a room with it on!
I have a gaming setup in my room will it will fully disinfect my desk and monitor and everything in the room just by having that on or is just for the room air and stuff
If it cleans every item in the room i will for sure buy this
It's supposed to clean, and disinfect everything from actual items to air quality.
@@WhatTheHeckMan dang i actually am good buy this now thats insane
👍👍👍👍

Thank you for the information! With your and multiple other comments, I have learned quite a bit more about these lights. Thanks for watching 👀

Totally, but the UV-C had to be contained and not exposed to skin. Ozone damages lungs.
Why bring something that could kill your plants or contaminate your food into your home?
🤦🏽♂️
Hospitals use these UVC lamps (much larger versions) to sterilize rooms in between patients.
My hvac unit has a uv bulb and a 5 inch wide air filter.
My comment they didn't like, but it's so silly to put tape on banana and not expecting
Is it hurtful to people?
What about bed bugs..?
It says on the box that it does!
I read that it only kills bacteria. Where did it say it kills bugs! I have one and it didn’t smell.
i have one, the advertisment I watched said it kills bed bugs, dust mites, mold spores, etc. I used mine once in my room where nothing alive was. I still have it and may use it again but am not in a hurry
ps, i did nor do i have bed bugs. I don't know if it helped with breathing and alergies as it had claimed to do on the advert.
