Jeanna:

Here is my box....waiting.  The cfl in the photo is a 60 watt that is just sitting there for the photo. I will use a 13 watt.

@gadget
69-101 ma
under load

thats my test results
check these videos   http://www.youtube.com/user/koolerization
the first pulls 89ma's
sec pulls 101 ma's

@xee2
i ordered some more parts three days ago
mosfets that will trigger with a 1.5volts
and some sidactors and more better transformers
hoping i can get the charge time down
i'm almost got a unmodded 13watt cfl to burn steady
watching it blink real bright and fast is enough to keep going on this circuit

@Bill,
I mean lit up! 

@Xee2,
Do you really have that secondary connected back to the battery?

@Kooler,
If it is just a plain secondary it usually does not draw more than the transistor, but with a connection across the transistor it might.

without the second stage the jt don't draw but 45ma lighting a cfl
but when i use the secondary to charge my cap or cap's that is when it doubles it draw

I looked at it a little while ago...
Is the circuit as xee2 has drawn it with the secondary going into the battery?

That probably makes it not much of a transformer; and, all the amps in the battery can get involved if it is.

I guess it would be more like a third primary than a real secondary, right?

thank you,
