This is why I wanted to know about the ciggy lighter. I've got a little strip of seven LED's that run from one. So far I've only got four to work. I've always loved the idea of playing with UV light so now I've got a chance to have a small fiddle. These are just snaps of me playing to see waht would happen. I'll try and get the others LED's the work and find something interesting the photograph. You get some great effects with different colours.
