Here is my replication.
Parts:
GE Helical 14W cfl
GE Biax Electronic 15W cfl
4.7uF 50V axial electrolytic capacitor (Radio Shack 272-998)
100 ohm 1W metal oxide resistor (Radio Shack 271-152)
SPDT 9VDC mini Relay 12A contacts (Radio Shack 275-005)
Niehoff DR174/AL179 ignition coil 2.1ohm prim 14470 ohm sec (Parts America NIEDR174)
Niehoff DR25CS/DR25 condensor (Parts America NIEDR25CS)
Yuasa EnerSys NP5-12 12V 5.0Ah sla battery
NTE125 Diode (Fry's)
Basically the same parts as Imhotep used, except a different coil/condensor brand.
I used 2 cfls in series.
I haven't measured anything yet or tested the recovery.
If I understand radiant energy correctly, you should be able to chain several bulbs together with little loss of energy.
Lights flicker some and are not as bright as when on AC.
