This LED Can Shine 80 Years on a Single Charge!

Running out of batteries for the flashlight can soon become a thing of the past if William Henry has his way. An applications specialist at Ireland’s Tyndall National Institute, Henry got his team of researchers to developed a way to make a lamp from micro LEDs that will shine on for over 80 years with a single charge,this LED is called micro for a reason — it's tiny.The light measures only 5 microns across compared to the 300 microns across that a standard LED measures and requires only a few billionth of an amp to operate and emit light literally through a man’s lifetime once you fully charge its coin-sized battery.

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!
