@ Mr Mag
Could you post a diagram of where the power factor capacitor is placed in the circuit, I got an idea for a fix, but I need some more info.

It would be illegal to modify an existing CFL, then put it back into service, but, could the capacitor be placed midways in a very short extension plug and light socket? that way, the CFL isnt opened up. Am I on the right track, Tim?

I posted a item on CFL's on some other thread...according to the report they emit harmful radiation.

Hi !

sorry to bump in

this seems simmilar enough (at least biffilar)
http://jnaudin.free.fr/html/tepcoil.htm

1. has really enyone tried discharging one cap at input and filling up the other at output
after that calculate reamaining energy in both caps.
2. can someone try to energize diode and meassure input current using circuit above (but using biff coil from Joules Thief)
now led will lit when Tr is open and allso when Tr is closed from BEMF...

just speculation...I'll try it - maybe cascading is possible...

Electricme,

I am not sure exactly where to place the capacitor in the circuit.

I could not find the original document that I read this in but here is another version of the same story. http://sound.westhost.com/articles/incandescent.htm
The information about power factor is close to the end of the page.

Interesting article.  I also use LED lights, as opposed to incandescent or cfl bulbs.  I have a lamp which is the equivalent to a 60w incandescent, but only draws 4 watts..  Led is the way to go..Less power consumption, runs cooler, outputs a pure white light, and lasts longer.  You can also drop an led and its not gonna break.  On another note, I once met a teacher in college that said he knew a guy who worked for a company who manufactured light bulbs, and had said they came up with a light bulb that would last a lifetime, but said it was covered up, since it would decrease their profits..
