Bulb busting light source invented | The Register

Researchers working on organic light-emitting devices (OLEDs) have made a critical jump that could finally call lights out time for the humble bulb.

I have been waiting for news like this since I read that 20% of the US' energy usage comes from light bulbs. I have tried compact fluorescent bulbs, but they give off a horrible light; and the full spectrum versions are too bright and too much like daylight - very weird when you are indoors (not to mention being really expensive). I have been looking at LED bulbs, but they are not bright enough yet except in groups (and still expensive).

So the 2 big questions about this are … when and how much?
