Step 3: So What Have We Got?
(moderately) High Voltage diodes
(moderately) High voltage capacitors - some of these have nice long leads so they can be clipped off without even needing to unsolder them.
Big Inductor - on the order of 2.5 milli-Henries for a 20W lamp.
Smaller Inductor - exact value unknown.
Toroidal Transformer (useful for Joule Thief!)
High Voltage Transistors or Mosfets
High-voltage, High-temp "spaghetti" - this is usually silicone coated fiberglass; useful stuff in certain applications, and hard to find and expensive if you have to buy it.
The Fluorescent Tube itself - if this is still good, you can do things like replace the ballast with a DC inverter and have a battery-powered CFL.
