Using a old burn out CFL replacing with LED using the CFL electronic ballast?

 Hi i have several burned CFL lamps that i want to convert to led using the N26 screw and ballast of the cfl to replace the ones in my lighting

Same quest here. I have a philips PL-C 26W/841/2P and thought I could just snap off the base and solder wires to a standard lamp socket for and LED bulb. Philips' website states the voltage to the PL-C is 100V. Now I am doubting there's enough to power the LED bulb. Perhaps the ballast is in the fixture and not in the bulb?

Turns out the conversion was easier than I thought. The bulb was for a bathroom fan/light. A NuTone model 8663RF I think. I opened it up to have a look. The fluorescent ballast was wired with a standard 120V plug. I removed the ballast, cut off the plug. Attached the plug to a standard screw-in 120V light socket, removed the fluorescent lamp socket from the reflector, and mounted the 120V socket in its place. I only had to drill 1 hole to mount it. Looks professional as I used threaded lamp tubing and hardware to mount it. The fixture is rated for 26W so I put a label on the socket that stated LED ONLY! Here's the exploded view: http://www.storeforparts.com/Parts/List.aspx?Brand=NuTone&Model=8663RF
Compact Fluorescent Lamps (CFL) are an efficient and long-lived lighting source. However, like all lamps, they eventually "burn out" and sometimes fail prematurely. One alternative I thought of to recycling failed lamps is to reuse the parts for custom LED lamps. I would look up CFLED projects on the web. 

Here is a starter, it is not from instructables but it is a DIY Project
Hi, I'm the creator of the CFLED and just wanted to say thanks for the interest in my project! I'm now selling kits which make it easy to build your own CFLED lights. They're available at http://www.sicada.com/products Have fun!

LEDs don't need ballast. They need a power supply of the right voltage and sufficient current.

I remember a diy article somewhere about using the cfl base and installing led's in it's place.  You can't use any or atleast much of the old electronics though.  It looked great and in the end you end up with an led replacemet for the cfl light.

I couldn't find the link but if I do later I'll repost it here.  It may have been a make or hackaday post.

I doubt you could use the same ballast. Although small, the CFL tubes still need an initial high voltage to ionise the gas within them. However, they are reasonably efficient, this leads to them having very low current requirements.
I suppose, ultimately what I'm saying is that the operating voltage is too high (though you could fix that depending on how you arrange the LEDs) and that the initial voltage spike will most likely damage the LEDs (unless you start looking into dealing with this issue with MOVs and the like, though this is probably more effort than it's worth). To top it all, the current will probably be too low to drive LEDs (depending on the wattage of the CFL that burnt (and therefore the wattage of the ballast)).
