This explains it all

They are just basically a mini fluorescent lamp but they don't need to heat the electrodes to start. Most regular fluorescent tubes have to preheat before the electrodes can emit electrons and strike the mercury vapor inside to create the light.

I made a high voltage power supply that takes 12 volts and steps it up to a few thousand volts which lights up 6" flourescent tube (for a battery powered camping lantern) for a case light. It dosen't preheat the electrodes though, it just fires a high enough voltage through the lamp to start it so it runs similar to a Cold Cathode. However, this isn't very good for the lamp since a regular flourescent light needs to be preheated; otherwise the electrodes will splutter and cause the ends of the tube to turn black. Cold Cathodes can run like this without blackening the ends.

Despite their name, they will still get warm while they are running. They will probably get about 40C
