The coil-EEFL lamps, which are operated with DC driving circuit, have studied. The figure of the merit of the coil-EEFL lamps is the quantum efficiency (ηq) that is given by the emitted visible photons by one moving electron in the FL lamp. The electrons in the FL lamps move on in the superconductive vacuum (R = 0) in the positive column at above room temperature, giving rise to the astronomical ηq = 1013 visible photons (m3.s)-1. Miraculously, the developed coil-EEFL lamps in the parallel connections light up with WDC = 0, without the sacrifice of the illuminance (lm.m-2). Furthermore, the scraped 40 W-HCFL lamps revitalize to the coil-EEFL lamps, promising the operation life longer than 106 hours. The shallow gap between phosphor screen and positive column can be made by side by side arrangement of the low voltage CL phosphor particles and PL phosphor particles. The coil-EEFL lamps in parallel connections may contribute to the Green Energy Projects of UN.
