Alex Baker, manager of government affairs and public policy for the Illuminating Engineering Society (IES), recently wrote an article for LEDsmagazine, where he expanded upon the topic of LED lifespan.
As Baker walks us through an LEDs lifespan and how it is calculated he also states, “many companies are trying to do the right thing, making responsible LED lifetime claims fully informed by industry standards, while others are clearly attempting to profit from the uninformed and underinformed.”
