Here’s great video about Organic OLED lighting and the OLED 100 project.  The goal of is to develop all the necessary technologies needed to produce efficient OLED products for exploitation by the European lighting industry.

Lighting accounts for a quarter of energy costs in Europe. Replacing outdated light bulbs with more advanced devices is an efficient way to cut energy bills. Science and industry have joined forces in a European project to develop cheap and stylish alternatives to modern lighting called the OLED 100 project. Targets set by the project include achieving 100 lumens per watt power efficiency, more than 100,000 ‘lifetime hours’, a unit area of 100cm by 100cm, and costs of €100 per square metre or less.
