A new study has shown that LED bulbs save energy throughout their entire lifespan, from when they are manufactured to their eventual disposal.
The report, which was carried out by German lighting company Osram, looked at the energy used to make LED lamps to calculate a life cycle assessment of the items, reported the New York Times.
As well as the manufacturing and disposal of the bulbs, the researchers examined how much energy is used in packaging and transporting them, the news provider continued.
By using six different global warming indexes and estimating the carbon emissions created, the researchers were able to conclude that incandescent bulbs use nearly five times as much energy as LED lamps.
"The difference in energy use between incandescents, compact fluorescents and LEDs is definitely significant," explained chair of the study's review committee Dr Matthias Finkbeiner to the newspaper.
Last week, medical firm Lumie announced that it is releasing a skin therapy treatment which uses LEDs to ease inflammation and kill bacteria.
