Light bulb working for 117 years

Andy Millar
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 smiley

I do like reliable technology...


Cheers,

    Any idea what the lifespan of a continuously powered LED (just a plain LED, not a LED bulb) is?
