Does anyone remember this, or know if the company is still around to back up their 20-year warranty?

Sorry Ive never heard of it, but I found a cool story on a lightbulb that has run continuously for a 100 years
http://www.firehouse.com/news/2001/6/11_bulb.html

Back when Hector was a pup, corrugated sleeves for packaging General Electric’s “long life” incandescent lamps had a notice that generally recommended use only for cases where

1) labor cost for replacement was very high, or,

2) electricity cost/kWh was very low.

Their apparent rationale for the notice: energy efficiency of these specific lamps was poor, so discouraged for general use.

Aside — This type of lamp was manufactured with brass-screwshell bases and not aluminum, so were desirable for cases where the lampholder screwshell was also aluminum, potentially making the lamps difficult to later replace if condensation occurred.

Mike,

We have a couple threads on it in our 'Nostalgia' Area, including some additional information from it's caretakers:

In regards to that bulb that has been running for 100+ years, I have to wonder if it is on a UPS and generator to keep it from cycling off and on during blackouts?
