type with the 20W circular fluorescent tube. I was really surprised to find
nothing but an iron-core choke in the base.. no starter device, nada.. just
a choke in series with the line cord (and the lamp) I assume. It +is+ the
type where you must hold down the power button for a moment to light it, so
perhaps that's a (manual?) starting mechanism. But in any case, I was a
little puzzled that's all there was to it, so to speak.
