Testing UV disinfecting lights

KPRC 2's Amy Davis tested UV disinfecting lights.

You should teach people to differentiate the real uvc lamp and fake led uva, uvb product because general consumer won’t know the different

I could hardly believe it when I saw this video about UV lights show up on YouTube because I had just been wondering about them. That same day I had told my husband that the air purifier in our room needed new UV light bulbs. Soon after I started wondering just how effective UV lights are. Thank you so much for answering my questions.

Man was spot on with the light directly hitting the mold

[FlowWithJeaux]

I'm so grateful this was created. So helpful!

[AKMLOVE]

Thank u so much for this video they are now selling these at dollar tree

[LadyGoza]

Nice! I just got mine on clearance from Walmart for $5.00

I bought a UV toothbrush case. I'm hoping it works, but even if it doesn't, the fact that it's still a case means it'll at least stop particals from landing on it when I'm NOT using it.

A while back, I got a letter from PhoneSoap saying that the FDA is forcing PhoneSoap to discontinue their wand(SurfaceSoap). PhoneSoap told me to return it and get a replacement which is something like that box.

You can tell the real germicidal UV-C lights by the type of bulb, the wavelength and the power output. First off, the cheap LEDs DO NOT WORK! The best cost effective solution is the low-pressure mercury vapor lamps. These are similar in technology as neon lights but with a different gasses. The mercury vapor emits germicidal ultraviolet light at 253.7nm (254nm) and is not visible to the eye. The blue color you see is usually emitted by the Xenon gas which is only included to stabilize and make the tube more efficient. This bulb also has to be powerful enough to be effective. We sell a 5 watt rechargeable wand which we thinks is the minimum power to make the sanitizer effective with convenient treatment times. It is fast to use and covers more than twice the area than the handheld shown in the video. The battery operated unit shown in this video is rated at 2 watts, has a 3 1/4" long dual tube, and does not offer much power or have much treatment area making it inconvenient to use, especially for larger objects. We also have a specially designed collapsible box to place your items to be sanitized that works with our 5W wand. By placing items in the box, bacteria, viruses and mold are destroyed by both the UV-C and the small and safe amount of ozone created by it. There are LED's that are being developed emitting a wavelength of 222nm which is an effecting germicidal and also safe to humans, but the cost is prohibitive and no consumer products use them.

I love the part where they show me the before and after comparison side by side .. I guess ill just have to trust the media on the science ..

[ttboy]

I wonder if the box was lined in aluminum foil, would it have performed better?

[xlnuniex]

I just received mine from amazon for $100. It’s meant for an entire room, not a wand. I want to know how well they work.

[groovejet]

Do they work...Used for decades to disinfect surfaces. I think there's your answer.

I’m curious about the THEORETICAL use of these for emergency water treatment. Can they kill Giardia? Cryptosporidium? Let’s say I have a really bad hurricane, am in desperate need of water, and boiling isn’t an option for whatever reason… how effective could this theoretically be? What about aquarium UV-C lights!

[knotmortal]

Love these

[noahirizarry]

Where can I buy the exact same light at??? Like the exact same one

[SHREDTILLDEAD]

Umm proof the average are obsolete, and ignorant. This method has only been in use since 1920 something, and no one has ever bothered to ask why not use it on a larger scale.

[noahirizarry]

I’m doing this as a science fair project do I need like an incubator or something to keep the bacteria warm so they can grow???

[denniscarey]

These low power devices are going to work in a matter of seconds as they say. Normally, it would take about 20 to 30 minutes to be effective. If you want an effective UVC sanitizer, you would need to purchase one of the commercial units for about $150. These units can put out about 45 Watts of UV light. You definitely will have to wear gloves and protective glasses to use it!

But Trump mentions UV and media go crazy, Trump also mentions chlorine Dioxide and media say its bleach which it isn't, Sodium Hypochlorite is bleach. Saying it's the same is like saying Carbon Dioxide is the same as Carbon monoxide because both have carbon in it. People are so gullible and media know it and are having a laugh at people's expense.
