After 20+ years of use, my family's first compact fluorescent lamp finally died. To mark the occasion, I de-soldered the terminal leads and took some photos of the (likely working) ballast:
Not long after this light went out, my bedroom CFL failed. In comparison, it was only 4 years old!
I've used the electrolytics from them, when I knew they failed prematurely, or the lamp was broken.
