Nearly 130-Year-Old Light Bulb Continues to Shine, Offering Insights for Cambodian Science and Technology

A light bulb installed at Fire Station No. 6 in Livermore, California, USA, in 1901, continues to emit light to this day, holding the Guinness World Record for the longest-burning light bulb in the world. This is according to reports from the San Francisco Chronicle and Popular Science magazine. The bulb, named the 'Centennial Light,' was originally a 60-watt bulb manufactured by the Shelby Electric Company in the USA and designed by French engineer Adolphe Chaillet. Currently, it consumes only about 4 watts of power, which helps reduce heat and prevents the filament from burning out quickly. Scientists have not yet been able to clearly determine the reason for its exceptionally long lifespan. However, it is believed that its carbon filament is of higher quality than that of modern bulbs, and the fact that it is not frequently turned on and off is also a significant factor in extending its life. Today, the 'Centennial Light' has become a tourist attraction, with many people traveling to see it in person at the fire station. For the local firefighters, it is simply a bulb that provides regular illumination in their daily lives. Information source: Koh Santepheap Khmer
