You don't often notice a light bulb until it goes out and any disassembly on your part was likely violent and accidental, but there is some interesting tech in LED bulbs. Hackaday were interested in what happened to shorten the lifespan of these type of bulbs which were originally marketed to last much longer than current models; indeed much longer than the actual bulbs ever managed to do. They took a look at what is inside current generations of bulbs to see what differences exist between a bulb marketed for 15,000 hours versus one claiming 25,000 hours.
Along the way you will learn about the light bulb cartel which artificially limited the lifespan of incandescent bulbs and the famous Centennial Bulb which has been continuously burning for well over 1,000,000 hours.
"So, what happened to those 100,000 hour residential LED bulbs? Were the initial estimates just over-optimistic? Was it all marketing hype? Or, did we not know enough about LED aging to predict the true useful life of a bulb?"
