YORK, Pa. - A bulb that may have been burning since the early 1900s has been discovered glowing dimly in the basement of the Fire Museum of York County. Dennis Kunkle, director of facilities for the York County History Center, sent pictures and a description of the old bulb to an antique radio forum, which told him about the origin of the dual filament bulb. What facts are you familiar with?

It is a lamp which will give you either a 16 candle power light or a 1 candle power light, without any waste of current by simply turning down as easily as turning down a gas jet." This is in reference to gas lighting, popular around 1900.

Observing the bulb in operation, low is indeed equal to the light of one candle.

A flexible contact on the base of the bulb allows the second filament to be turned on by screwing it in a little tighter.

The smoky coating inside the bulb indicates that it probably contains carbon filaments. Carbon filaments were replaced with tungsten in light bulbs after about 1920.

Dennis Kunkle can't say for certain how long the bulb has been operating in the basement of the fire museum, but since the building was built in 1903, it is possible that the bulb has been with the building since the beginning. Are you surprised to read that the 100-year-old light bulb still works?
