Joule Thief

I have an addition to my family of fluoro lighting circuits.

I must not be hooking the cfl up correctly.
I can only start to get it but it will not go to the second half of the cfl.
I could only find a 13w cfl, but I cannot think that is the problem

I am not using any caps on this one. This is powerful
My new MK1jeanna hybrid style winding..
But this tube is 15 watts, and I have over 535v this time.
2.3khz
2T,10T>300T
TIP3055
base resistance anywhere from 500-1ohm
this is a good transistor.

There is some ambient light but most of the light comes from the tube.

edit
I need to clarify
the gold wire is 26awg which I got from gobrushless. (thanks again, hazens1)

@ ist

oh... roger that

and @ jeanna... very nice setup
i copied your old setup on the 3.38 toroid.. to find that it will charge a cap to 506 volts.. pretty fast
so i might copy this one to try to get the xtra volts with the mk1-jeanna setup

thanks guys

oh... happy turkey day to all

Jeanna:

Great job on the tube lighting!  You know, I had the same problem in my one attempt to light a cfl with the Fuji.  Plenty of volts as we know but, only 1/2 of the cfl would light...just 50% of the coil. (Like every other row)  I checked all of the wiring and connections to the bulb but I never could get it to all go on.

Hopefully, my Jeanna Light replication will go better.  maybe we both got some kind of defective cfl?  Or possibly we damaged it in some way when taking it apart?

got it

HA!
