In the year 1901 Dennis Bernal, owner of the American electric power station “Livermore Power and Light Company” made a gift to the local fire brigade – a Livermore light bulb! On the 8th of June that same year it was switched on and is still glowing to this day. According to the Book of Guinness World Records, it is the oldest glowing light bulb in the world. To prove this, a webcam sends every ten seconds a picture of the glowing light bulb to everywhere in the world. Its nickname is conveniently the “Centennial Light”. However, the light does not shine very bright, since it only contains four watts.
