What is the difference between ccfl and eefl?
CCFL (cold cathode fluorescent lamp) is different from EEFL (external electrode fluorescent lamp) in that the glass tube of the CCFL contains a small wire electrode that conducts the voltage to excite the gasses in the tube. The glass tube is molded around the electrode and that junction creates a possible point for the gasses to escape and the lamp to fail. EEFL is a completely sealed glass tube with a metal cap or conductive paint on the end acting as the electrode. When the proper voltage is applied to the external electrode, a capacitive connection is established between the electrode and the gasses within the tube and the lamp illuminates. Because the electrodes in CCFL's are in direct contact with the rare gasses, CCFL's run warmer than the EEFL's which are completely cool.
