Cold Cathode Lights are vacuum tubes or gas filled tubes. Unlike other heater operated cathode tubes, there is no cathode heater in cold cathode tubes. There are many types of cold cathode tubes, some have beta radiation source to start the ionization process in the gas-filled tube. Others cathodes may have rare earth materials coating for enhanced electronic emission.
