- 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 25, 2019 · A revolution is upsetting the lighting business as LED lightbulbs replace energy-hogging incandescent ones. This is good news for consumers and the environment; using less energy reduces the...
Jun 28, 2023 · During the unprecedented times of the 2020 pandemic, the lighting industry witnessed a surge in demand for highly efficient light sources. Amidst this change, the focus shifted towards LED lights capable of offering a high luminous efficiency ranging between 130 to 180 lumens per watt (lm/W).
Nov 18, 2014 · Compact fluorescent lamps (CFLs) – or energy efficient bulbs, as they are more commonly known – were supposed to spell the end of the light bulb in the 1970s. But despite rising to prominence...
They weren’t a viable option anymore after 1880 when Thomas Edison patented a bulb that could last for 1500 hours. Slowly over the 20th century, the lightbulb developed to become more efficient. With the creation of fluorescent bulbs, a single lightbulb could last for over 10 years of regular use.
Jun 9, 2021 · The result has been the phase out of inefficient light bulbs and manufacturing capacity shifting to the production of LEDs, creating the industrial scale required to drive down costs quickly. Under EU legislation, this year – 2021 – could see the last incandescent and halogen light bulbs sold in Britain.
