We can certainly say that this lamp holds the record for the longest run! It makes those geeky LED lights look short-term. The lamp was first installed in a fire department hose cart in 1901 and then moved to Fire station 6 in Livermore, California in 1976. For the last 35 years, the bulb is connected to an emergency power generator to avoid turn on and off cycles which will destroy it, and since then, it burns with no interruptions. The Centennial Bulb will celebrate it's 110th anniversary of light-giving next Saturday. Isn't this just amazing?
