This UVC light can be used to kill Bacteria/Viruses on N-95 type face masks. VERY carefully remove the face mask, then place the exposed side of the mask in very close proximity to the UVC light for 20 mins to be sure everything has been inactivated/killed. **DO NOT LOOK DIRECTLY AT A UVC LAMP!**
Will it affect the mask ? any chances of skin cancer?
I assume it would work fine on a 3M half mask respirator as well? And will it eventually damage the plastic or silicone at all? Make it brittle?
@@dlandes14 UVC damages plastic and rubber with repeated use. For your mask, unscrew the filters, spray the filter openings with the 70% alcohol and allow to fully dry, then wash the mask with warm soapy water. You can also spray the entire mask(with filters removed) with lysol disinfecting spray, allow it to sit 2-3 mins, this rinse off with warm soapy water.
@@electronicsNmore do you know if there is a way to clean the pink disk type p100 filters without ruining them? I am hoping to find some of the plastic cartridge type filters so I can just clean the outside plastic parts but the pink disk filters are all I have for now. For context, I work in the ER and plan on using a full face shield over the mask to hopefully add another layer of protection to the mask. And also, I saw they make UV devices for phones and CPAP masks and things. Wouldn't hey be damaged as well? I appreciate your advice!
I had been thinking about making a device containing a UVC light that could have household air circulated through it to kill viruses and bacteria. About 20 years ago I had a Sharper Image Ionic Breeze and it had a UV light of some sort but I found the unit to be ineffective overall. My first question is how long would a virus that's in the air have to be exposed to UVC light in order for it to kill it? I can imagine the device would only only expose a certain amount of air for 1 second or so. Do you have any thoughts on this or are there devices on the market similar to this that have proven to be effective?
Great design with good concept for safety. Keep it up!
Excellent. Safety feature designed with minimal electronics and it performs very well.👍
Yes, thanks!
I have a UVC Meter (I'm an electronics development engineer working on UV germicidal projects for the last couple years). An online search returns results ubiquitously that the atmosphere blocks all UVC light, both on commercial web-sites and on *.GOV websites. But according to my testing, it doesn't!
I measured UVC from the sun to be about 60 uW/cm^2, which is higher than all of the UVC bulbs I've been working on (I use
Great info! Thanks for watching
What about the moon? Does the moon emit UVC light? ...asking for a friend.
@@Floortile83 I'd guess not, it doesn't reflect very well off of objects that aren't shinny (buffed stainless eg.). I'd guess rock doesn't qualify as shinny.
I'm not usually awake when the moon shines. Early to bed, late to rise, it keeps the bags from under my eyes ;-)
Next time I'm up during a full moon I'll give it a reading. We'll see if I can find this video again to post my reply.
@@Floortile83 Well tonight is a super-moon. It's the best time to measure moonlight with my UVC meter. I got a big fat whopping 0 uW/cm^2 :-). So no, the moon doesn't reflect UVC light.

Thank You!
great job, thank you for sharing knowledge!!!!
Thanks, and you're welcome!
Cool project, thanks for the video. However, I was wondering, aside from your innovative safety features, what is the advantage to this set up versus buying a 120v sprial uvc cfl, or 2ft fluorescent uvc bulb and corresponding fixture. (I have both).
All UVC light is directed down very close to the surface, and Petri dishes can be placed in very close proximity to the light.
Thank you so much for posting this I bought 2 bulbs with 2g11 base and one with S(t4) bulb 36 watt and one with T17,5 with 95 w. I really don’t know what type of ballasts to get, if they are universal or specific? I would appreciate some advice, I usually find my way to learn things but there is not much on this topic
Use CFL buld circuit board or electronic balast from hardware/elecrical store it's not critical but heater filaments in bulb have cap. in series with 2 wire a/c power limited current by inductor.
amazingly brilliant! You have a great mind. Do you know where I can find out how much UVC wattage I need to project this bacteria/virus disrupting light to kill at 10 feet?
You'll need to research that. Info is available online. Thanks for watching!
Nice build. I like your tilt switches, but I think you will find that if you tilt your lamp at a diagonal, you will still have a situation where it will not turn off like you want. I don't think you can get away without additional tilt switches.
It's possible that there's a spot where it may not trigger, but I haven't observed it yet. Thanks for watching!
hi, can a uv submersible light for aquarium be used without being submersed in water ? will it heat up if just put in enclosed box to sanitize?
The bulb is not in contact with the water, it's inside of a tube and water flows around the tube and gets exposed the UVC light. Should work fine, but don't use indoors if the lamp also gives off ozone.
Got a question. Is there a reason I cant use this type of bulb in my trouble light? It same type of bulb I use in it and same Watts except might have to build a cardboard/tinfoil to deflect light that comes off the sides of it?
It may work if the wattage is similar, and the trouble light has a fluorescent tube. Try it. Make sure no light is directed toward you or your hands. Place object on black fabric to prevent reflected UVC.
Does anybody knows if any plastic glasses blocs uv-c light? Or uv glasses have an especial treatment.
The glasses below will block it, but cover up your skin.

I have a UV-C battery wand, I don’t know how many watts it is. I just wave the wand over the keyboard and ipad and food preparation area. You mentioned that it takes 2-3 minutes to kill bacteria, does this mean that briefly waving the wand around is ineffective?I usually wave it over things 3-4 times taking say 5 seconds. To determine the watts (or power) I have to measure the current consumed. Not sure if the tube is a high voltage discharge tube.
A simple wave of the wand isn't enough. You need at least a 2-3 minute exposure at a close distance from the object. Thanks for watching!
Great video. Did you make the lam your self_
Make what?
@@electronicsNmore the lamp?
@@AlizadehMa I made the lamp holder out of PVC and Bakelite.
How do you calculate the exposure times needed to kill something like SARS-CoV-2 while taking into account such parameters as wattage and distance from surface? Is there a way to calculate how much do lamp reflectors improve exposure times? I've been trying to find a formula for the past 2 days and I got nothing.. I don't want to underexpose surfaces I am trying to disinfect, but I also don't want to run these UVC light for unnecessarily long times due to ozone production.
The UVC light I have doesn't produce ozone, or extremely little. If I place my 9W UVC lamp within 1 or 2 inches( 2.5 cm - 5 cm) for at least 2-3 minutes, that should be enough, but to be really sure, I do 20 mins. I'm sure there's a formula based on distance and light intensity, but I'm unaware of it. Thanks for watching! Please share the video link with others.

I hope people become familiar with the dangers of UVC first, and then learn how to use it responsibly.
I ordered a 7w aquarium lamp to make a box enclosure to sterilize the few surgical masks I have because I dont have an oven to use. How do I determine what size box I make, how far the bulb should be from the mask & how long is long enough to leave it inside to kill the virus. I'm worried about leaving it in too long or sitting the mask too close to the bulb because I want to avoid degrading the polypropylene material of the mask.
Hi Teri. Line the entire box with aluminum foil, place the lamp at the top center 3" away from the mask. It should only take a few minutes, but to be safe I'd do 20 mins. Suspend the mask in the center of the reflective box.
@@electronicsNmore OK thank you !
I love the one you made. Do you think you could give a few tips to someone looking to make a portable, battery powered version? (Possibly even a tutorial?) Like what would I need to light to a UV bulb like that as a base and how would I know what battery requirements the base would need and/or how can I control that? I had a weird idea: i thought it would be cool to be able to use an old vape mod (vaping) that uses a rechargeable 18650 batterie. The other benefit would be easy charging for the 18650 battery, as it can be charged within the mod with just a cable.
--- But before getting ahead of myself, i think I'd need to learn the basics. most of the solutions i find information on are all centered around regular wall plug in power source.....so how can I make what you made, but with batteries as a power source. Also is there any way to use rechargeable 18650 battery?
how do you wire this? I'm trying to make one myself for a project but i have a difficulty understanding how i can wire this to a power source or something.
and can you use pvc instead of the bakelite?
You can use whatever you like. :-)
Wondering, do you think those UVC LED light with only 2 Watt consumption, are really emitting UVC and not only UVA.
They pretend to be UVC emitting but safer because the low intensity. I don't find any evidence on that. I would like to share the link on Alibaba product but maybe better privately. Thank you
The only way to tell is by using an electronic tester.
Is it necessary to vent the ozone produced from these bulbs or are they safe levels?
Very low levels usually won't irritate your eyes, lungs, mucus membranes. Use UVC lamps with ozone in your garage, porch, etc.
The comment three to five minutes is actually quite a bit of time. The exposure time is measured by wattage and distance mostly. And so this 9W lamp should only need about 15 second exposure at most at the short distance that your video shows for sterilization. Little half watt lamps only take about 12 second exposures at one-half inch from the sanitizing spot, according to the directions my unit requires that I purchased at a local merchant.
Not based on all the studies I read. 3 to 5 minutes is recommended.
Viewers should be aware that companies such as Coke use UV to sterilize their water which is forced in piping and QUICKLY exposed to UV as it flows. The water travels at a rapid rate. Pathogens' cells and nucleus do not need much exposure time to UV so only seconds are needed at 15W on up and at a distance of only a few inches (less than a foot). Too much exposure time is not only a waste but surrounding area can be damaged depending on what is exposed such as skin or plastics. The video here shows a really resourceful person making a clever product that is very useful. I'm just sharing valuable information collected over many decades of the use of UV and research. I realize manufacturers give exposure time but it is very inconsistent. If one looks at the function of UV they would realize how quickly cells are damaged by this concentration of UV that is not available in sunlight like so many on youtube are sharing. This shortwave energy is absorbed by the ozone layer which is in jeopardy around the globe today in spots.

Higher the wattage, the less exposure time required. :-)
How do you test uvc to see if it does kill bacterial or other viruses? Bought a supposed uvc wand of Amazon but think it is a black light not uvc thanks
You cannot confirm unless a culture is done. It works if UVC.
Have you tested this on dust mites, skin mites, bed bugs? That would be a very interesting video for many people.
UVC light kills all those mentioned. Thanks for watching! Glad you enjoyed the video!

Do you need a ballast for the lamp or direct power?
Ballast
Hi, what are the parameters/type of power supply? Couldn't read it in the video.
+Ján Golian You can buy 9W UVC power supplies online. Just do a Google search.
Thanks For Watching!
@@electronicsNmore I think the reason why he's asking well I know this was a long time ago but I think the reason he asked was so he could buy and alternative power supply with the same specs as it would probably be much cheaper to buy. Getting the socket in the power supply separately would be no real big problem and probably much cheaper as I say
where can i find that power supply? couldn't find it on eBay
No longer available. The link below is the best buy for 11W UVC. You'll need to shield one side of the lamp like I did. Maybe slide a small cut pvc pipe over the lamp with foil on the inside.

What is the power supply used? Can’t make it out on the video
It was included with the 9W UVC tube.
i have a question how much watt showed it be for a room. i saw some on line but it does not say the watts. also ozone is a gas which can be harmful to humans and animals. if i do get a uv light for my kids bed room. how long should i leave it on and if ozone is harmful to humans how long should i wait to enter back into the room. also how often should you use the uv light in your home everyday once a week once a month im not sure how the room uv lights work. do i keep it running all night can you explain to me how the uv room lights work or is there a way to make my own with better uv power and affordable
Hello. For a room, use an ozone generator. Remove all people, plants, and animals, then allow the generator to run for 1-3 hours depending on the size of the room. After it's finished, you'll need to enter the house holding your breath so you can unplug the unit and open all the windows and doors. Wait 2 hours to enter, less time if it's windy outside. For an object, use a UVC light at least 9W, and make sure it doesn't give off ozone.
@@electronicsNmore ok thank you but what size watt bulb for a bedroom. Also do I open the windows before or after I use the generator. I'm thinking if I open the windows and doors after I use the generator that would defeat the purpose of killing viruses or bacteria in the air if I let it back inside from opening up the window after I use the generator?
Does you UVC light emit ozone? Are there uvc that dont emit ozone?
Some do and some don't. 253nm germicidal lamps do not. 220nm lamps or lower do produce ozone.
@@electronicsNmore Thanks for the reply. One more question does far-uvc emit ozone?
where did you buy the light bulb socket?
It was part of the assembly. I bought the AC power supply, which came with a power cord and socket.
would this unit have enough power to kill airborne bacteria in an air conditioner intake plenum?
+Brian C
Hello Brian. Usually a small hole is made in the side of the air handler to insert the UVC tube. The wattage used is dependent upon the size of the AC unit and the speed setting of the blower motor. The 9w shown in this video would be fine for a small unit(1 ton). For larger units you need 18W and up.
Thanks.
Is it constant voltage or constant amperage power source?
Higher voltage between 250 and 400v, using a low level of current.
How many volts is the power supply... I had one of these bulbs and I saw a specification from the person who sold it to me and he said it was 120 volts so I put 120 volts to it and it immediately blew the bulb
You need a LOW current 400V ballast.
@@electronicsNmore I dont see a ballast in your design, is it build in in the PS?
@@UrbanPlumbers Yes. I designed the holder with the safety tilt switches. The light came with the holder and ballast that plugs into the AC receptacle.
can you specify the power source you are using. Model number. Thanks
It was included with the UVC lamp. They usually output 300-400V at low current. Thanks for watching!
another great video. Are you familiar with the "Steri-Pen" used for water purification? Its a battery powered UV light, used for purifying water. Have used it to purify water when traveling through S.E. Asia. I've never gotten ill from drinking water that would otherwise be unsafe after using the Steri Pen
+rkstew
Hi there. Yes, I own a steri-pen. They use a small UVC tube.
Can you use fish tank uv light instead. Thanks
Yes, those are UVC inside a black plastic tube or the sump.
how is the UV-C lamp powered? is AC, DC, high voltage?
AC volts. 250- 400VAC. Thanks for watching! Please share the link to this video on social networking sites. Stay safe.
Hey man can you Disinfect with a uv light like the girls use for there gel finger nail polish
No. Those units use UVA. Sunlight is UVA & UVB. UVB kills, but it takes hours of full unobstructed sunlight from directly overhead. Thanks for watching! Be sure to watch the video I uploaded to my channel yesterday.
What about uvb ? will that still work on virus but a little slower?
It works, but not nearly as fast. A fairly strong UVC light damages bacteria and viruses in 2-3 minutes, UVB could take 20 minutes, and UVA maybe 1-3 hours.
@@electronicsNmore thanks for the reply 👍 and stay safe
Nice, does it work well against covid19?
UVC kills everything. Thanks for watching!
Mine makes ozone how do I get rid of the smell on the mask?
It will dissipate if left in open air.
how much is it to make the whole thing?
i don't recall. I picked up all the parts online fairly cheap. Look on Ebay. Thanks for watching!
what voltage does this lamp require?
+Online Police
I am not sure of the exact voltage, but the voltage is high. Likely several hundred volts or more.

It would, but the uvc may damage the plastic.
How is the UVC light harmful to your skin?
+milton hutto
UVC light penetrates deeply into your skin causing damage/mutations.
+milton hutto skin cancer potential for longer exposure
still waiting...
222nm wavelength? Because it would be REALLY nice to be able to decontaminate humans with Far UV-C light, and not burn them.
Hard to believe that a far UVC won't damage cells, when 253nm does.
