NEW Old Stock (and I mean OLD)
Long life incandescent lamp which we had as spares for some special American equipment way way back in the day ... an antiquity these days but who knows? I have some old SONY audio equipment that used 100V front panel lamps (scarce as hens teeth but this lamp will not fit as it is too large a diameter) Not a lot of equipment sends 100V up to the front panel for display purposes but I hope someone can find a use for these ....
GF (USA) - Miniature Incandescent Lamp
CML (USA) still produces a range of very similar incandescent lamps
Type: 6W 125V (carrier also has 610 impressed into the side)
Operating voltage: 115V ~ 125V
Thick glass envelope
Brass screw base - I believe this is called an Edison E12 Candelabra type
Double hung filament design (very similar to the photograph below)
Cold resistance: 225 Ohm
Identification of the lamp is printed in Black around the top of the Brass thread
DIMENSIONS:
Although these "look similar" to your stock standard (well they used to be!) 6.3V pilot lamps, they are slightly larger.
These lamps will not screw into a standard base for those lamps.
GLASS ENVELOPE: 12.65mm diameter x 19mm height (looks and "feels" very thick)
BRASS SCREW BASE: 11.5mm diameter x 13mm height
CONTACT BUTTON AT THE BASE: 1.75mm
This means the TOTAL lamp height is 33.75mm
TESTING:
I have a few of these ... every lamp has been cleaned, tested and checked
DC COLD resistance of the filament is nominally 225 Ohm (variations across each lamp in the range 220 ~ 235 Ohm)
Applied 110V (most convenient supply I had to hand) and the glow is a nice soft Yellow/White light
COSMETIC CONDITION:
NEW
OLD Stock
Clean*
*These have been in our stores for quite a few years, still in the original tray, so I took out my trusty Brass cleaner so they "look nice" and I could then easily read the identification details.
I rigorously cleaned the Brass and checked carefully for any separation between the glass envelope and the base - NONE at all, very secure (I have some old projector lamps where the cement used had failed after such a long time)
Kept/stored in the original suppliers tray but now also within a sealed plastic packet with some bubble-wrap
