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 draw up a schematic. I figured I’d share it with you. It should be fairly easy to construct if you needed a light, efficient, flicker free ballast for your shop or garage or heck, even your living room!
