Frequently asked questions
The invention of the electric light bulb is considered a major historical milestone. It revolutionised human society and spurred further advancements. The light bulb changed the way we design buildings, increased the length of the average workday, and jumpstarted new businesses. It also led to new energy breakthroughs and inspired inventors to create new, revolutionary products.
In 1835, the first constant electric light was demonstrated. For the next 40 years, scientists around the world worked on the incandescent lamp, tinkering with the filament and the bulb’s atmosphere. In 1860, English physicist Joseph W. Swan developed a primitive incandescent lamp, which used a carbonized paper filament in an evacuated glass bulb. In 1879, Thomas Edison and his team at Menlo Park produced a light bulb with a carbonized filament of uncoated cotton thread that could last for 14.5 hours. Edison also made other improvements to the light bulb, including creating a better vacuum pump and developing the Edison screw, which is now the standard socket fitting for light bulbs.
The light bulb helped to reduce the use of oil lamps and gas lighting, leading to the development of more energy-efficient light products such as LED bulbs. Incandescent bulbs are inexpensive and easy to use, but they are inefficient as only about 5-10% of the energy they produce is converted to light. This has led some governments to phase out incandescent bulbs in favour of more energy-efficient options such as CFLs and LED bulbs.
