Here is the schematic of a simple flouroscent lamp driver circuit based on two transistors.The circuit uses capacitive ballasting for driving the tube.An 8 W standard flouroscent tube can be efficiently driven using the circuit.
The two transistors (2Sc 1983) with associated components forms a oscillator around 1KHz.The oscillator is wired so [...]

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 [...]
