Thomas Edison crowns 14 months of testing with an incandescent electric light bulb that lasts 13½ hours
Thomas Edison's first successful light bulb lasted for about 13.5 hours when he first demonstrated it. However, he and his team later improved the design to last for over 1500 hours.
Thomas Edison's best light bulb stayed lit for over 40 hours in a test conducted in 1879. This was a significant achievement as it far exceeded the performance of other light bulbs at that time.

No, the first light bulb that Thomas Edison invented is not still operational. Over time, light bulbs burn out and lose their ability to produce light due to the filament burning out. However, Edison's invention laid the foundation for modern lighting technology.
The filament in Thomas Edison's light bulb was made of carbonized bamboo. Edison experimented with various materials before settling on carbonized bamboo as a durable and long-lasting option for the filament.
