Interesting light. What is the operating frequency of the ballast? I'd be surprised if it was much higher than 110 Hertz and 60 Hertz isn't out of the question.

Holy crud! This is awesome! DC-powered preheat fixtures are the coolest thing ever. I need to find one sometime...

good luck!
this is apparently a rare bird.
no reference anywhere to be found online.
probably wasnt cheap in the mid 60's.
ge power transistors were "high tech" then!

well i used this light last night at a friends cookout/party.
the power was off so i ran home and grabbed this light and a big gelcell.
hung it from the ceiling poles of a screenhouse and fired it up.
one of the guys there has one!.
it was bought in 1966 at western auto.
its dead and headed my way for repair.
so it could be as early as the datecode of the cap which was 6312
