They're used in a prehaet fixture, most commonly found in the 15-22W( FS-2) fixtures, the T5 preheat uses them too, 4-8W is standard FS-2 and 13W uses a built in auto transformer ballast and FS-4 starter
old preheat F40 fluorescent fixtures use starters too those are FS-4
Jace: do you have any of the rare 120V pulse starters?
Well nice collection anyway, I have no starters. xD What were starters used for anyway? Like which kind of florescent fixture?
