Researchers have developed a new way to make LEDs, and that could reduce your household lighting bills by as much as 75% within the next five years, according to a recent article in Science Daily.
Gallium Nitride (GaN) is a synthetic semiconductor that can be used to make LEDs. It emits brilliant light and uses very little electricity and make that as their green steps.
However, until now, researchers had to grow GaN on expensive sapphire wafers. These high production costs kept GaN from widespread use.
