3 pack of clear / transparent lamp for 12 light mains operated sets. The
lamp style is a conical or tulip lamp with a 20V 3W rating.
was commonly used in Pifco, Lyvia and Dencon light sets. It doesnt
matter what brand your lights are, as long as the specified replacement
is a 20V 3W type with an E10 thread.
The E10 thread type relates to the
diameter of the thread crests, ie the distance betwen the crest of
threads on each side of the lamp. Some lamps are E12 so be careful that
you measure your lamps before ordering. Most of the older 12 light sets use
this E10 lamp which is now quite a difficult lamp to source.
Let's look at the lamp specification:
- Lamp type: Incandescent Tulip / Conical lamp
- Colour: Clear / Transparent
- Lamp Voltage 20V AC or DC
- Lamp Power: 3W
- Lamp Current: Typically 0.15A, 150mA
- Thread Size: E10
- Lamps Supplied: 3
Here's some useful
lamp advice. When the lamps are in service keep your eye on them as this
lamp like the ones you allready have normally fail to a short circuit.
In a series light set this keeps all the other lamps on but it means
that the 20V dropped across the failed lamp is divided amongst all the
others. The more that fail then the more strain is on the others so keep
your eyes peeled for lamps that are out and get them changed quickly.
This lamp has a 10mm diameter thread, please check your size before ordering. When measuring with a ruler the E10 lamps have a thread diameter which appears to be around 8-9mm whilst E12 lamps appear to have a thread diameter of around 10-11mm.
Old set of lights pre- war unable to find bulbs till finding buymystuff we now can keep them going for a few more years.
Thank you for you site.
