I think we linked to an article on this forum a few years ago about this low-wattage lamp. Now, it's 107 yrs and counting. they just don't make em like they used to...

It looks like it is running at about 50% of the rated voltage. I bet if you put a 240v lamp in your luminaires at home they would last forever too.

I bet if you took a 1000 long-life rough treatment 240V bulbs and put them in 110V surge suppressed and line conditioned sockets several of them would last 100 years.
They just happen to have noticed that that bulb has lasted that long, numerous bulbs - exactly similar and made by the same company have burned out long ago, we just don't keep track of them. We also don't run them on a line conditioner and surge suppressor. Does not surprise me in the least.

I have some 20 year old "sign bulbs" that are still working. In fact I have never replaced one. That is what I have in all the lights over my screen cage.

It's a 4 watt bulb with a VERY thick filament. HP

They also said "battery". So, not only is it surge and line conditioned, it's also on UPS. Not a cheap one, I hope...
I LOLled at the part about batting it for luck and tossing nerf balls at it until they realized how old it was.
