Are you still using 2 resistor in your circuit to protect the transistor ?

I bet it would last longer without it.

@ jeanna

Just for you, and just to make sure it really works, I put a Christmas tree bulb across a 0.5 uF capacitor (actually two 1 uF in series) charged to 800 volts. This is what happened (attached video). So, it really does work.

Thank you xee2,
Is this a circuit like mine? (like your drawing), or is this Kooler's with the added ignition coil?

Thank you,

My total base resistance is 65ohms
I have the rheostat wired in place but it is wide open.

What would last longer? the spark?

thank you,

even my little 1 "  gold mine flashes an un modded cfl ... 

cam does it brighter tho ...  also uses more ..... 

i found another cfl it flashes slower .. and brighter ..

but they all fill and fire ...  ring or cam un modded or modded in some cases ...

w

all done with same aa

now what if i add 2 or 3 from aa source ....  glow bright ?   constant ....   un modded right out the pack ... 

bet ya !

You know the resistor i mean , the one you use to put before the circuit , i guess you replaced it with a rheostat .

Longer i mean run time.
