Research recently undertaken by Siemens says that the lifecycle efficiency of LED lights is equal to that of compact fluorescents.
Measuring the lifecycle efficiency involves looking at the energy to manufacture and dispose of the product, in addition to the energy it uses whilst in operation.
The report was released by Osram, which is owned by Siemans, with the testing taking place by the Siemens Corporate Technology Centre for Eco Innovation, and reported on in the New York Times.
There aren’t many details yet though as to how the research was undertaken or the numbers behind the claims. For example, was the LED light used in the comparison of equivalent brightness to the CFL.
But it does show that LEDs are getting closer to being the light of the future.
