CONTEXT: A Cheap, Tacky, Yet Clever Small Fluorescent Light
Look, no starter! I have one of these: I used it as a night light so I didn't have to turn on the overhead lights in the communications room at Fourmilab when going in at night to “turn it off and on again” or some such. I never imagined what is, or isn't, inside. They use the low impedance of the arc struck in the tube to (mostly) turn off the heaters. The main power switch is also a piece of…work.
