Very crap UV floodlight (Patreon)

Horrible eBay ultraviolet floodlight (with schematic)

In the very best tradition of direct imports from China, this light has a few technical issues. I got this for comparing to other blacklight style light sources, and although the LED versions are more of a deep violet as opposed to proper UVA, they do perform pretty well. Most dayglow pigments will respond very well to light that extends well down into the blue area of the spectrum. Not sure how long this one would last in real use though, especially given it's impressive list of technical issues. In fact, if you have any of these lights in UV, "burple" , white or other colours then consider them as a high shock risk. Definitely not something you'd want where kids could touch them, or mounted on any metal surface. I do not regard these as suitable for outdoor use at all. (Or indeed any use!) The dark side of products like these is that people are buying them and installing them in the belief they are safe. Initially they will work, but they will inevitably fail, and when they do there's a high risk of them failing in a dangerous state. Especially if used outdoors where the casing may rust and disintegrate very quickly leaving exposed live circuitry.
