How did eddison improve the light bulb?

Thomas Edison improved the light bulb by developing a practical and longer-lasting incandescent bulb. He experimented with different materials for the filament and eventually created a carbonized bamboo filament that lasted over 1,200 hours. Additionally, Edison designed an efficient vacuum inside the bulb to prevent oxidation, enhancing its durability and performance. His innovations made electric lighting more accessible and commercially viable, revolutionizing indoor lighting.
