CCFL TV backlight tubes (Huntingdon PE29)

These are from a 2008 Sony Bravia TV I stripped. I don't think I am going to do anything with them. There were 12 originally but I don't have a good place to keep them and I have damaged one of them consequently. One other I broke while removing from the TV. There are 10 intact ones. They each measure 73cm including the end conductor leads. I don't know what voltage they need. If anyone has an idea of what to use them for then these are yours.
