re building a uv flashlight jhawk panix com john hawkinson writes my main question is the bulb where can i get uv bulbs do they need a lot of power etc etc he ones i have seen are all fluorescent tubes maybe you could find a small tube to go in one of those hand held fluoro lanterns one other thing a friend of mine mentioned something about near uv light being cheaper to get at than actual uv light does anyone know what he was referring to blue lights ultra violet by definition goes from the blue end of the spectrum that people see to the radio spectrum x rays cosmic rays etc possibly you could get light at the fringe of visibility which people with false eye lenses can see easily since it s your lenses that soak up most of the uv however since most people use uv to get other things to glow and the near blue is less energetic it would probably not work as well if it worked at all lecture on basic atomic physics fits in here about electron transitions quantum leaps and stuff moz
