USA/WORLD. The most famous lamp of the world is installed in a firefighters station in Livermore, California. Is alight to 111 years. Uninterruptedly. Its power is 60 watts but currently uses just over 6% of that potence. It is an object that arouses the curiosity of scientists for an obvious reason: their longevity in operation.
