Scientists Create LEDs That Lasts 80 Years From Battery the Size of a Penny

Ireland (TGW) – A team led by William Henry at Ireland’s Tyndall National Institute has created a miniature light emitting diode (LED) that will last 80 years.

The micro LED is 20 times smaller than a conventional LED and only requires a few billionths of an amp to operate. It can operate for 80 years from energy stored in a coin sized battery.

"We can produce visible light from nanoamps," Henry said of the FLAME project, which stands for "future lighting applications for miniature entities."

The LEDs will be first marketed as an alternative to lasers.
