long do you expect your flashlight to last without needing a recharge? A few hours, perhaps? How about 80 years, how does that sound? Because that's just how long newly developed micro LEDs can last on just a single charge.
Of course, this LED is called micro for a reason — it's tiny. Like 15 microns across compared to the 300 microns across that a standard LED measures. But still, the technology is there, so it could be expanded to make larger, more practical LEDs that might last a less impressive but still awesome 5 years on a single charge. It'd be tough to complain about that.
