Self running is probably a misnomer. It looks like it is running from a charged capacitor.

I found out that this is old EM stuff but I think we could incorporate it into a JT circuit! What do you think!

....also connect one winding of your secondary to the collector_the other to one end  of your CFL, while the remaining CFL connection to ground or back to the collector.

Crowclaw,
That sounds really weird to me.
If you electrically connect the primary to the secondary you will lose much of the advantage of the secondary.
It is magnetically connected and therefore the battery has little to do with the secondary output, but,
if you connect the secondary to the primary...
1- it might overheat the transistor, and,
2- it will take the juice out of the battery like a lead sinker. on a fishing line.

Hey gang !
@jeanna
   Here are some very cool COOL White leds . They are the purest white with no blue in them at all and resemble a normal light bulb, not golden but white and the neatest little ball Diffusers I have ever seen. They are on sale at Kmart for 5 dollars and are 50 to a pack and called pearl lights! I like them and these are lit by the Jeanna light core unmodified so they are just a tad under brightest from Ac but they put out some great light. Just thought Id share them being all the Christmas stuff is on sale now and its time to stock up on goodies fairly cheap and they have neat Diffusers
