Lecture 11: Radiometry (59)
arilato

There has been a lot of controversy for a long time about the lifetime expectancy of lightbulbs, including the current LED lights. The gist of it is that all the lightbulb companies came together to monopolize the sale of lightbulbs, and conspired to artificially lower the life expectancy of lightbulbs so consumers would buy more. Whether that is true or not is up to debate, and there are still active investigations into this issue. A good read on this can be found here: https://spectrum.ieee.org/tech-history/dawn-of-electronics/the-great-lightbulb-conspiracy
