Cheaper LED's coming soon

LEDs now grown on silicone vs. sapphire wafers.
GaN, grown in labs on expensive sapphire wafers since the 1990s, can now be grown on silicon wafers. This lower cost method could mean cheap mass produced LEDs become widely available for lighting homes and offices in the next five years
Energy resources are going to improve in typically one of two ways. First is to find new sources of energy. Second is to find better ways to conserve. LEDs fall into the second category.
