This is the schematic of an electronic ballast model 234SLESW designed for running a pair of 4 foot T8 or T12 fluorescent bulbs. It claims to have an Energy Star rating when used with F32T8 bulbs. I picked one of these out of a dumpster and it was broken so I had to [...]

Here is the schematic of another fluorescent ballast circuit from a lamp I acquired along with the 80W electronic ballast. It actually contains a pair of the circuit in the diagram, one for each bulb. The ballast itself is unlabeled, but the chassis sticker calls for 25, 32, or 40 Watt 48″ type [...]

This is the typical circuit from a scanner that drives the flourescent lamp. There is also usually a 2KV capacitor in series with the secondary of the transformer to limit current, etc. They can be used as a general high voltage source for all kinds of things.
