As objet d'art and enduring symbol of American reliability and ingenuity, it's been lauded by senators and presidents.
It boasts a website -- www.centennialbulb.org, drawing a million hits a year -- a historical society and even a webcam that allows curious fans to check on it 24 hours a day.
The Livermore lightbulb, you see, never gets turned off, which many suspect is the secret to its longevity.
Hanging 18 feet above the floor at the end of a black cloth-covered cord, the little light with the filament the width of a No. 2 pencil lead is unprotected by any lampshade.
Firefighters won't even dust it. Touch it, jokes one captain, and "you get your fingers chopped off."
They guard their light with a surge protector and have a diesel generator and a battery as backups. To them, the bulb is the embodiment of their always-on-duty ethic.
For years, Bramell was known around the Livermore-Pleasanton Fire Department as the keeper of the bulb, the unofficial curator and caretaker who fielded queries from the public and visits from tourists. Over time, he developed a boyish wonder at its craftsmanship and spunk. From a vantage point directly beneath the bulb, Bramell says, its filament even spells the word "on."
Livermore's bulb has burned for nearly a million hours. Even now, in its old age, Bramell will stack it against any New Age fluorescent, halogen or high-pressure sodium bulb out there.
