i think that is a unmodded led bulb

Amazing. I have never been able to get an unmodified CFL to light. What bulb are you using?

Yes, kooler that is correct.

@xee2,
this is a Lights of America 19leds lightbulb. It is brighter than a cfl.
This comes with 19 leds in series and a circuit of 2 caps a fuse and a pair of resistors.
It is equivalent to about 25 filament watts (even though the claim is 40w)

I believe it was the caps that continued to hold the juice so that even though the switch went off the toroid continued the oscillation and used up the battery.
The reason I think this is because if I started with the switch off and then added the battery, nothing happened until I turned the switch on, but once on it would not turn off.

Thanks Bill. the jt is so small. If I had planned it, I would have used a 4 AA battery holder and wrapped the jt into it along with the battery.
Maybe I can still do that.
The battery is still on with a clip.

@Wilby... a keg is a fine idea but I would want the full 700v  for a bright light.
With enough light, my beer would be safe.

I am still happiest with the way I made the globe light which takes the least amount of volts.

thank you,

jeanna

@ will ...  i recon that the next trip is the best one ...  : )

i have litt un modded cfls right out the pac! 

not constant ...  thats probally a good thing .. tho .. i used a c battery to power a cam board then through a microwave toride ..  then a cap then the cfl ...  when the caps in the cfl fill they fire ...  what is the output voltage and amparage of a standard cfl?   so 2 jt's fireing 2 unmodded cfl units to a coil ...  catch the RETURN ...

ist!

Impressive. So how did you do it?
