Just rip open a couple of those failed CFLs you have.
There's a 15 or 20uF 200V capacitor in each one.

That begs a question from somebody who has no clue electric-wise: Is
the voltage of a capacitor just a capacity limit? i.e. can a 100v
capacitor be replaced with a 300v capacitor with no problem?

**Depends on the capacitor. For most types of capacitors, you'll have no
problem. Electrolytics are a different matter. They should always be
operated at some large percentage of their rated Voltage (say: at least
70%). Otherwise they may depolarise and the value could shift
dramatically.


I'm guessing the capacity in microfarads is critical. i.e. a 15uF cap
cannot be replaced by a 30uF cap.


**Depends on the application. With decoupling caps, it's not a big deal.
In fact, for such applications, a larger value may be an advantage.
