Edison tried thousands of materials for the filament.
All about The Electric Light Bulb
Thomas Edison developed a practical, long-lasting electric light bulb in 1879. Many inventors had made earlier light bulbs, but Edison's version used a carbon filament that could glow for many hours in a vacuum without burning out quickly.
A light bulb glows when electricity heats a thin filament until it becomes very hot and gives off light. Modern LED bulbs produce light in a different way and use far less energy than traditional bulbs.

Frequently asked questions about The Electric Light Bulb
Did Edison invent the light bulb alone?
No. Several inventors made earlier light bulbs, and Edison improved the design so that it was practical and affordable.
What is a filament?
A thin wire inside a bulb that glows when electricity heats it.
Why are LED bulbs more efficient?
LEDs convert more electricity into light and less into heat, so they use much less energy.
