FL lamps are operated with coexistence of disparate external and internal electric circuits. External electric circuit works as a help of formation of internal electric circuit in Ar gas space of FL lamp, with no electron flow. FL lamp actually lights up with moving electrons from cathode to anode of internal electric circuit formed in Ar gas space. The cathode and anode are assigned as either one of (a) the volumes of glow light (±3G) on phosphor particles or (b) heated corona light (±4G) on the metal electrodes. The developed coil-EEFL lamps use the (±3G) volume without heat. Adequate outer diameter of the coil-EEFL lamps is within 1.0 X 10^-2 m with Ar gas pressures higher than 7 X 10⁴ Pa (> 50 Torr). The developed coilEEFL lamps light up under AC and/or DC driving circuits. Under the AC driving circuit, capacitor Cphos involve in WAC that is lower than 0.1 WAC of the established HCFL lamps that involve the CAr. Under the external DC driving circuit, both of Cphos and CAr do not involve in the power consumption. Consequently, WDC = 0. The operation life is longer than 106 hours. The Coil-EEFL lamps surely contribute to the urgent project of COP of UN with reduction of generated electric power consumption more than 30 % on the world.
