- Prior to incandescent light bulbs, lighting was created by candles, oil lamps and gas lighting.
- Historians attribute up to 22 different inventors of the incandescent light bulb before Thomas Edison.
- The first concept and demonstration of heating a wire to produce light was by Ebenezer Kinnersley in 1761.
- The first practical commercial light bulbs were created by Thomas Edison in 1879.
- The filament used in Thomas Edison’s first practical commercial light bulb came from his observation of a bamboo fishing line while observing a total solar eclipse.
- Incandescent light bulbs are very energy inefficient, less than 5% of the energy required by it is needed to produce the visible light.
- The average lifetime of a household light bulb is around 1,000 hours.
- Incandescent light bulbs are sold in different wattages, like 60 watts or 100 watts. The wattage dictates how much energy the light bulb uses per hour.
- Many countries are phasing out incandescent light bulbs to reduce energy consumption. This is done by banning the manufacturing, importation and sale of them.
- There are a few alternatives to incandescent light bulbs, and they are halogen lamps, compact fluorescent lamps (CFL) and light emitting diode lamps (LED).
- Incandescent light bulb alternatives use less energy and have a greater lifetime.
- Halogen lights have a lifetime of about 2,000 hours, and that’s twice as long as a incandescent light bulb.
- Compact fluorescent lights have a lifetime of about 10,000 hours, and that’s 10 times longer than an incandescent light bulb.
- LED lights have a lifetime between 20,000 and 30,000 hours, and that is 20 times longer than an incandescent light bulb.
- Compact fluorescent lights contain small amounts of mercury in them. Even though they use less energy than Incandescent light bulbs they aren’t good for the environment.
- According to estimates from the U.S. Department of Energy, the increase of the use of LED lights will reduce the world’s energy costs by over $30 billion USD.
- The Centennial Light is an incandescent light bulb located at Livermore-Pleasanton Fire Department in California. It holds the world record for the longest-last lighting bulb. It’s estimate this light bulb has been burning since 1901.
