According to the expert's analysis, OLED lighting is more than twice as efficient as regular incandescent light bulbs by using a new process that involves tiny micro lenses, cranking out 70 lumens of light per watt of power, compared with the 30 lumens per watt of GE's latest OLEDs. While these fantastic new lighting sources won't light up every house for a few more years, they'll be a whole lot better than current compact florescent bulbs. Surely, the current compact florescent bulbs are slightly more efficient at 90 lumens per watt, but their color rendering is harsh, they're laced with toxic mercury, and don't last nearly as long as LEDs and OLEDs. And, as OLEDs get even more advanced, you'll be able to have entire walls lit up with their friendly glow.
