After a recent event in Hong Kong where people attending a fashion event were exposed to dangerous levels of short wave ultra violet energy, I decided to make a video on the different types of UV tubes available on eBay. That includes the dangerous UV-C type that can cause eye and skin damage.
One thing I missed in the video was the importance of UV in the making of vitamin D in your body. A reasonable amount of exposure to sunlight is actually desirable.
