There's an interesting story on Philips Lighting plans over at Tech-On, which obviously includes OLED Lighting. Philips are already shipping samples for quite some time (here's our review). Philips say that currently their OLED has an emission efficiency of 10lm/W to 20lm/W.

They have already achieved 80lm/W "in the lab", but it will take at least 3 years to achieve 50lm/W at the production level, and 5 years to go beyond that.
