Hello, This is a project I did after recieving a 3 1W led constant current driver I got from ebay (2.00)
it uses
2 heat sinks I had lying around 
Soda can top
3 1W leds with star base $2.00
Silicon glue (because hot glue always melts on me)
A dead CFL bulb (dont break the glass & dont stab yourself a flathead screwdriver and small hammer helped me open mine without breaking glass
Some heat shrink tube
$4 not super bright but I had fun and it is bright enough for what I wanted
I didn't get a picture of the driver inside of the bulb unfortunately but its not too hard to figure out with AC +/- become arbitrary with these drivers

It is fairly simple but can go wrong If you don't make some connections properly
I didn't do it but a CFL usually has a fuse on its wires and leaving that In would have been helpful 
I'd like to build another one except brighter and more stable soon
what does the opened cfl look like? do you have a pic?
