- Congress established the first national light bulb efficiency standards in 2007, which were signed into law by President George W. Bush. Starting in 2012, the law required new light bulbs to use 28 percent less power than existing incandescent lights — essentially ending the sale of the older, inefficient bulbs.

Traditional, or incandescent light bulbs were invented over 100 years ago in 1879. These were extremely inefficient, with only 5% of the electricity being converted into visible light. Although a fantastic invention, we soon began to realise incandescent bulbs were just not sustainable enough – we needed more efficiency.
The next big launch into the lighting market was the halogen bulb. These were developed by Elmer Fridrich and Emmet Wiley in 1955and used the same filament technology as traditional bulbs but run at higher temperature, making them slightly more efficient. However, this wasn’t enough, and inventors continued to work on their ideas in order to bring ...
Before the phase out of halogen bulbs though, compact fluorescent lamps were brought to market. by Edward E. Hammer in 1976. These were the first energy efficient bulbs on the market, using around 70-80% less electricity than equivalent traditional light bulbs. CFLs typically last for around 8,000 hours of use, which is approximately 50 times longe...
Due to a massive difference in energy consumption, LEDs have become the most popular, and simply the go-to choice in almost every lighting scenario. Surprisingly, LEDs were first invented in 1927, but have been developing ever since. 2002 saw the first real adoption of LEDs for residential use as they become commercially available for approximately...
Nov 22, 2013 · In 1913, Irving Langmuir figured out that placing an inert gas like nitrogen inside the bulb doubled its efficiency. Scientists continued to make improvements over the next 40 years that reduced the cost and increased the efficiency of the incandescent bulb.
Jun 9, 2021 · Some estimates suggesting that an overnight global switch to highly efficient LED light bulbs could cut 1,400 million tonnes of CO 2 emissions. This would avoid the construction of 1,250 power stations around the world – a monumental saving both in terms of carbon emissions and air quality.
Mar 21, 2024 · In 1911, the introduction of tungsten filaments significantly improved the lifespan and efficiency of incandescent light bulbs. Throughout history, the quest for efficient and reliable illumination has driven technological advancements.
Jul 31, 2017 · Over the years, developments in the LED industry have turned LEDs into a viable light source by boosting their lumen (the measure of a light’s brightness) output without compromising energy efficiency. Today, LED bulbs are 75% more efficient compared to incandescent light bulbs.
Throughout the 20th century, researchers worked to improve on Edison’s design, looking for ways to make the bulb more efficient and last longer, with limited success. In the latter half of the century, researchers started looking for new ways to produce light more efficiently.
