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.
Edison's best light bulb stayed lit for around 40 hours. This experiment took place in 1879.
Edison's main problem was finding a long-lasting, practical filament material for the light bulb. He experimented with various materials before discovering that carbonized bamboo filament could last for up to 1200 hours. This solution greatly improved the practicality and success of the light bulb.
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.
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.
