New Micro LED's last for 80 years on a single charge

From Newlaunches.com:

William Henry, an applications specialist at Ireland's Tyndall National Institute, has developed a new LED that can keep going for years on a single charge. The micro LED--which is significantly smaller than conventional light-emitting diodes--requires only a few billionths of an amp to operate. Thus, it can survive for quite a while on a limited power source. One of the researchers on the project had one running constantly for two-and-a-half years on his desk. Then someone damaged it while moving it around. One member of the group calculated that it could last 80 years (assuming no accidents) on the power stored in a coin-size battery.
