9-volt batteries light up an energy saving bulb
19 nine-volt batteries are used to power a compact fluorescent lamp. Since these lamps internally rectify the AC to DC and then raise voltage with high-frequency switching, feeding them with 170 VDC should do the trick. Beware: this lamp is rated for 220 VAC, not 120 VAC. For 120 VAC lamps, 10 to 12 batteries should be enough. Do it at your own risk.
