Just to brighten up a winter's Monday morning (for those of us in the Northern hemisphere), another thread on these forums has just reminded me of this light bulb which has been lit for 117 years...there's even a live webcam so that you can check it's still alight
But to be honest, it is not really a light bulb. It is only glowing slightly. It must be run under its rated Voltage, this will prolong the life of any tungsten filament lamp. It is more like a low Wattage heater. You probably could not read a newspaper in the dark if you were just a foot away from it.
