When visiting a synagogue once, I asked what happens if the Ner Tamid bulb fails. The answer I received was that this was accepted (presumably as an "act of God") until such time as it could be fixed.

Re: Nice little bulb.
You could be right but I don't remember any buttons at all. Just push the bulb into the already live holder. It's possible of course it had a clever arrangement underneath so that the lamp holder pins didn't become live until pushed down, I never put my fingers in to find out.

Re: Nice little bulb.
Yes, the most common types of these transformer adaptors were intended for use with 0.3 amp bulbs.
One brand even came with instructions as to what bulb to use for different supply voltages. "for 230 volt to 250 volt circuits, use a radio panel bulb of 6 volts to 6.5 volts and 0.3 amps. For 200 volt to 220 volt circuits use a 6 volt cycle dynamo bulb of 0.25 or 0.3 amps" These transformers were not particularly efficient, but still give more light at a lower cost than a neon lamp. The total input was about 3 or 4 watts, as compared to 5 watts for an Osglim lamp. The light was greater than that from a mains voltage nightlight lamp, and longer lasting. When I was young, a neighbour worked at Kingston hospital. Osglim lamps were no longer readily available for replacements in ward nightlights. The transformer adaptors were tried instead but in the end 15 watt orange coated pygmy bulbs were used. This was a backward step in terms of maintenance as they required replacement 4 or 5 times a year versus every couple of years for neon lamps. |

Re: Nice little bulb.
The Test Socket I remember at Boyes Stores needed both hands to operate. The holder had straight slots, not a bayonet, and the other hand was needed to press the button.

Re: Nice little bulb.
There is a video on YouTube by diodegonewild where he shows one of those adaptors that allow you to run low voltage bulb via a little transformer plugged into a lamp socket. The video is called some vintage items. He is from Czechoslovakia so it seems these items were spread everywhere

By the way, I feel there is a character to a neon lamp (which I loved in my childhood nightlight) that just isn't matched by a low-wattage incandescent.
