The only battery that fully light the cfl was a dead cell phone battery,it was so bright but faded out about 5 sec later, and worked a about 10 times , it was giving me about 3.4 volts and some 1.2 amps but it came with a circuit on it a suspect it had something to do with the high amps
because i have burned the circuit and amps reading when down.Further investigation are required .Also if you have 2 working fuji circuit connect 2 on one 4 foot tube then ad more tubes in series,if it works on 2 battery i have a plan to make it on one.

@ MK1:

I only have 1 working Fuji AA circuit as of now.  I am going hunting for "used" cameras in a day or so.  I hope to find many of these.  Then, I will try what you suggested.  There is so much more to all of this than I first thought.

@all

I just edited the content of previous post with picture, some specs and interesting observations.

If you have any question feel free to ask.

I took apart a newer version of the cfl lamp and look what I found.  There is no ferrite toroid here but, a very nice sized transformer.  I may try this on my breadboard when it gets here.  This is larger than on the Fuji circuit.  What do you think?

i don't think the step up ratio will be as high as the fuji circuit. would it work for mk's new circuit?
