Hello everyone,

Although I'm not in the electrical field I do have a strong interest in researching electrical lighting history. I heard my site mentioned above so I thought I'd jump in here. I agree with the reasons mentioned above about how and why this bulb has lasted this long. So instead of eating up more space I'll just pass a link on that you may be interested in. It seems this bulb has it's very own website and quite a fan club if you read the guestbook [Linked Image]

ok i'm going back 30 years or so here but i can remember a salesman coming along and selling my folks these little round green ceramic like pieces that went in the light fixture and then u screwed the bulb in.These gizmos were to make the lights burn for like ten to fifteen years or something like that they may have had to buy some special bulbs from ythis guy also i'm not sure,but some of the lights did last a long time and thinking back it seems the lights were kinda dim anyone remember these

Doc,

I remember these disc shaped things that rectified the power to DC and claimed longer life for bulbs. They were about 3mm thick and were sized for an Edison base, the ones I remember were blue, if that matters...

I think it was Popular Mechanics that I saw them in...

The disc shaped things were diodes. The cut off one half of the sine wave. You were getting half the power so the bulbs would be dimmer, create less heat and last longer. Also there was less amplitude in the vibration of the filiament, which also aided in longevity.

I've been in communication with members of the Livermore Heritage Guild and hopefully some more technical information will be coming.

So far the persons I've corresponded with are not aware of any special power source, only that a backup has existed for many years.

I forgot to say the filament is different.... I have heard both Carbon and Carbide used. It looks like it is quite heavy when the light is on... actually it is quite fine.

I wouldn't normally raise a thread this old, but apparently this Bulb is still going strong after 118 years!
