Meanwhile, after they mastered the process of making LEDs, they were quoted to have a half life of around 400 years, meaning that after 400 years continuous use, they'd be expected to emit about half as much light as they did new.

Now what did they go and do? They ramped up the power and made them blindingly bright, yet only last like 5 years or so, if you're lucky.
