![]() This is a sort of battery-powered thing that illuminates one 6" tube. In the video, Clive shows off a few different kinds of fluorescent bulbs that are available cheaply on eBay that generate different kinds of UV light.Īround this same time, someone at the office was getting rid of a small fluorescent inspection light. The fluorescent bulbs that are designed to radiate UV-C have to be made from quartz glass just so the light can get out normal glass tends to be fairly opaque to UV-C. It's not a problem for us in nature because it can't penetrate the atmosphere to reach us from the sun. UV-C is used for sterilization in air and water circulation systems, and can cause skin burns and eye damage. And then there's UV-C at 100-280nm, which is kind of nasty. Next is UV-B at 280-315nm, which is the kind that's largely responsible for sunburn (and, not surprisingly, is the kind of UV generated by tanning lamps). The first is UV-A at 315-400nm, which is not particularly harmful and is the kind of radiation that makes up most "black light" effects. You see, as Clive explains in the video, UV light comes in a few different flavors. This had the unfortunate side effect of leaving many in attendance with sunburn and welder's om attending a fashion event. ![]() Big Clive relays the story of a HYPEBEAST event where an uninformed designer used UV-C lamps in a number of booth fixtures because of their admittedly very cool and futuristic, ghostly blue glow. Some of them are what you might traditionally call "black lights," but some of them are slightly more sinister. ![]() ![]() If you don't have half an hour to learn about the UV spectrum, I guess I don't blame you, but here is the gist of the video: There are a lot of different types of fluorescent lamps available online that are all labeled as "UV" lamps. ![]()
