The GE 50 was the Lionel toy train bulb in many of the accessories.
Here's link to an old GE catalog; it has the bulb listed as "toy, train"
Later on there's the data for the bulb...
Not sure of best source; surely there still is one for these things but
a google search brought up an auction on eBay for a pack of 10; you may
have some luck looking for the toy train bulbs or Lionel.
They're rated at 7.5V and were powered off the "Acc" side of the
transformer for the train set. I presume the A/C cord leads to
somewhere inside the dollhouse where he hid the transformer.
I was gonna say, "model trains!". Despite the railroads long-ago
departure from the public eye, toy trains are still big business.
Many a metro hobby shop still caters to the model train crowd. Heck,
I live in a rather remote section of the CO Rockies, but a little town
20 miles away has a lone model trains shop. They should have all
kinds of light bulbs, either old NIB stock or replacement.
Another source would be commercial model makers. You know, the ppl
that make models of new buildings or housing developements. That's a
real and thriving business. Myself, I'd rewire the dollhouse for
LEDs. Jes butcher up a Christmas tree light string. Not like there's
any shortage, right now. ;)
They will, the "10V" setting on the meter means that the needle (I'm
assuming that you were looking at cheap analog meters, which are
perfectly adequate for what you're trying to do) will deflect to 100%
scale on the 10V setting. Analog meters tend to be most accurate around
50% deflection which would be 5V on that setting, you can still get
accurate enough readings in the 1-2V range.
To answer the question you actually asked, Fluke for digital or Simpson
260 for analog, but both are expensive and massive overkill for your uses.
replace "roosters" with "cox" to reply.
That makes sense. I think they had one for about $20 with a dial with
settings like 200v, 100v, 50v, 10v. It didn't opccur to me that that was
the range (duh).
The thing is, I asked the clerk in that department and was told that
they do not sell a voltmeter that will go down to 2.5 volts. I guess he
knew even less that I do. ;-(
If there is a Harbor Freight store nearby, you can purchase an
inexpensive multimeter for five dollars.
Girls can fix stuff too. I expect you are looking upon this as a
learning experience which is a good thing. If you can get some help
from a knowledgeable friend, it could keep you from breaking something.
If I had an heirloom like your dollhouse, I would want to restore it
rather than add space age items to it. ^_^
Yup, I agree with the "replace the bulbs" comment, also, you may want to
look into how to use your multimeter before actually using it. A cheap
one - which is all you need - actually has more special instructions
than, say, a new Fluke, if you don't have it set on the correct range
you can blow the fuse inside or burn it up, and we don't want that.
(don't feel bad, my Simpson 260 has the same special instructions and
that is a fine precision instrument. It's just the nature of the old
school meters.) I think someone already posted a link to a basic
how-to, but if you can't find it let us know and we'll try to dig out a
tutorial for it.

That's a nice little meter with a big display and it would appear to
have a good set of instructions included along with tech support which
is invaluable for someone not familiar with such equipment. The price
is incredible for the value. The built in battery tester is a wonderful
item for a anyone to have. I may have to add one to my inventory.
With at least 20 and possibly 30 meters in the house, cars and garage, I
finally feel I can pass up all but the free and very cheap meters from HF,
which do the job quite nicely. One is permanently mounted to monitor the
battery charger connected to the very infrequently used car we have. Even
has a nice bright backlite. I'll take every one they give me and even pay
$2 for them so I can give one away to some deserving person when the need
Yep, they've got a million and one uses. I spent $20 on a 12VDC panel meter
to install on my Dad's powerchair but I would have been much better off just
hacking an HF meter. The damn panel meter didn't even have a backlight.

Not really relevant, but I once found an electrc wheel chair in the
trash at the apartment building nearby. Not the little go-carts for
seniors but the most expensive medical kind, and with at least one
special attachment. As well as the overhanging bar that some people
use to sit up in bed, or get out of bed.
An acquaintance who used to be in the business came over and told me
it was worth iirc about 1000 dollars. By far the most expensive thing
I've ever rescued. He told me who to call and I gave both things to
the MD or MS society. They sent someone to get it.
When I found it, the battery was all charged and I kept tripping on it
when I tried to walk behind it, so the only way to get it home was to
I bately knew the guy it must have belonged to. He woudl sit
outside during nice weather and there was sometimes another guy in a
wheelchair who was there too. And I would wave as I drove by.
That's "barely" all right.
I suspect he died, and the apartment custodians just threw it away,
instead of trying to give it to someone who needed it.
"Better" in what way? :)
It's fine your purposes, go on.
But, I'll reiterate the advice I gave earlier...
Follow the cord in--it'll lead you to the transformer or you'll discover
indeed it is wired in series (highly unlikely I'd think given the
description of being switched). Then you can start from discovering
whether there's any output there and work down the line.
Or, maybe there isn't a transformer anymore or there's a fuse or who
knows what...but start at the beginning.
Think that would be a good SECOND thing to do.
FIRST good thing to do is to DETERMINE which bulbs should be used.
I got frustrated reading the autoranging meter thread and this one, so may
have missed something.
The bulbs were #14(2.5V), then they were #50(7.5V) then there was
the autoranging meter that was purchased, but we still have no idea
the voltage measured. Been lots of people jousting over conjecture.
Where's the damn voltage measurement?????
Putting 3A worth of 2.5V lamps on a 70 year old 7.5V transformer
that fits in a 1" cavity
in the dollhouse is unlikely to result in a happy ending.
Data provided so far is incomplete, inconclusive and contradictory.
If it ain't broke, don't break it.
What was it Rumsfeld was so fond of saying? You go to war with what you've
got. Same here!
I agree a measurement might be nice, but just seeing how bright or dim the
replacement bulbs that Jennifer has bought will give us a good idea of the
voltage. If they're super bright they probably should be replaced by
something with a higher voltage rating unless Ms. Murphy wants to help her
young friend learn about firefighting techniques.
I hope she will return for "final report" - all of the bickering and
side-tracking might have scared her off. )-:
