It has found that the active power consumption, Wcoil, of the single coil-EEFL tube that is not related with the energy for the generation of the lights, reduces to below 0.1 Wact of the commercial CCFL tube with the same brightness of the original CCFL tube. The coil-EEFL tubes allow the parallel connection with the single external AC driving circuit. ΣWcoil of 10 coil-EEFL tubes goes down to 0.03 ΣWact. The figure of the merit of the lighting devices is quantum efficiency ηq. The ηq of the FL tubes is the astronomical number that is 1013 visible photons per unit volume (m3) of Ar gas space per unit time (s) by one moving electron in the superconductive vacuum. The coil-EEFL tubes hold the unrivaled advantage with the power consumption and illuminance (lm m-2) over the solid LED lamps that have only ηq ≈ 0.5. A half of the injected electrons inevitably lose the energy by the Joule Heat.
