FL lamps are operated with the coexistence of disparate external and internal electric circuits. FL lamps light up with the
internal electric circuit, in which cathode and anode are separately, but simultaneously, formed by volume of glow or corona
light in Ar gas space at both ends of FL lamps, under the electric field from electrodes of the external electric circuit. The
developed coil-EEFL lamps light up under AC and DC external driving circuits. Under the AC driving circuit, only Cphos involve in
the WAC that is less than one tenth of the WAC of the HCFL lamps. Under the DC driving circuit, WDC = 0. The feature of FL lamps
is the superconductive vacuum at above room temperatures, giving rise to astronomical quantum efficiency [ηq
= 1013 visible
photons (m3
, s)-1 per one moving electron]. Each FL lamp is operated with 1012 electrons per second. Consequently, the coilEEFL lamps steadily emit the 1025 visible photons (m3
, s-1). The LED lamp has only ηq < 1.0. All components of the coil-EEFL
lamps reserve in the operation, resulting in the life > 106
hours. The developed coil-EEFL lamps surely contribute to the COP
project of UN with the reduction of the electric power > 30 % on the world.
