I have found a pen which lights up purple down the sides… when taking it apart I found a led (well what I think is an LED ;)). It glows bright purple and makes things (white things) glow like UV does when it is pointed at an item. Now my gut instinct is that it is just a ultra bright purple LED and that it is impossible to create a UV LED but I could be wrong. I can see who this could be done.


Any thoughts… (and could someone reassure me it is not a uv source :** laughs out loud **: )
