Hi all,
It's been a while since I've been here (used to be one of my favorite NGs).
I just picked up an old cantilevered magnifying work lamp - large
magnifier in the center, with the FL lamp surrounding it. The fixture
had nothing on the tail end of the cord (no plug, etc). While cleaning
it up I found that there was no ballast, nor any room for a ballast, in
the lamp housing. It has an old Leviton pre-heat type switch (push &
hold to turn on, then release; push again to turn off, like the 388
model) on the housing.
The confusing thing for me is that it appears as though this fixture
still has the original zip cord from the base up to the lamp housing,
where it is wired into the switch & thence to the lamp socket. One AC
lead direct to the W socket wire, the other to one black lead of the
switch - the two blue switch wires go to the red leads of the socket &
the other black switch wire goes to the black lead of the socket.
Is it possible that this ran off of 120 VAC without any ballast? I have
seen nowhere that one could be mounted, except at the end of the zip
cord farthest from the lamp. I also can find no wiring diagram for the
old simple choke (simply 2-wire) type ballasts; all of the "2-wire"
ballasts I have seen advertised have 2 wires going in and 4 coming out.
I want to get this thing going, but I am reluctant to just stick a plug
on it and try it out.
What say you?
PS - please respond to this newsgroup, as my email address is just a
spam-catcher. Thanks.
