@Wilby,
Please describe this in more detail!!
How many KV?
Disruptive discharge or electronic pulses?
Can you put it down?

@xee2,
Did you  ever figure out the maximum volts you could use with that filament bulb?
I mean the one that vaporized with too many volts.
I hope I saved the details on the pic you showed us. It was many many pages ago.

@All,
Does anybody have a suggestion for a way to warm up a cfl so it gets brighter when it is on?
I am pretty sure the cap+resistor in the insides of the unmodified bulbs is adding to the heat, so it would seem possible.
Also, since the youtube video showing the guy heating his english teapot with a bcap, I think this might help.
I believe any amount over 800v is beyond what a cfl will need to fully light.
So, I have over 1600 volts and I am thinking I should be able to corral that extra 800v into a cap or cap + resistor to make heat.

I will give it a try, but I won't object to constructive ideas to steer me on this one.

thank you,

jeanna

In my reality... I create a new year of mutual respect for all humans on our planet.

The voltage was only a few hundred volts, it was the amps that it could not handle. I posted a video of 3 series filament bulbs being blinked. That was also a few hundred volts but less current.

Thanks a lot Jenna, Gray and Merv for your super fast response and
valuable inputs.

I have made only 3 simple Joule thief running couple of LEDS and the HV one i mentioned
last time. I will try to do more experiments when I have time and post the results.

Once again I wish you all a HAPPY NEW YEAR!!!

Regards,
Gopal.
