Is LED light from UV sterilizer wand really UVC?
With so many fakes being sold out there, does this experiment prove this particular one is at least UVC light? For the experiment, a piece of plain white paper and the lens off a big magnifying glass were used. The glass was placed partially over the paper. So one side of the paper was covered and the other was not. Then a UV light source was shined over the whole paper. So there was on both the covered and uncovered portions of the paper.
1) A child's UV invisible ink pen was used. The result was everything looking exactly the same on both sides of the paper. So the color and intensity were exactly the same!
2) A supposed UVC sterilizer wand was used. Here, the side covered by the magnifying glass was significantly dimmer. So there was a huge difference in the color between the covered and uncovered sides. And it appeared the covered side wasn't as bright.
Here is a link with pictures so you can see for yourself what the results were: https://i.postimg.cc/SNLv4mf6/UV-light-test.jpg
I forgot to mention that the hand wand's light wasn't as bright to begin with as the invisible ink pen. So the uncovered side shined more brightly with the ink pen vs the hand wand. This is something you'll notice in the picture with the much brighter bluish from the ink pen vs a dimmer bluish from the wand. So it's additional information to help you decide if this indicates the wand is UVC.
