Japan's Lumiotec plans to start shipping OLED Lighting panels next month. These will be sample kits that include one  145mm x 145mm OLED panel, a controller and an AC adapter. The kits will cost ¥80,000 each (about $880). Lumiotec plans to increase production capacity in July and reach about 40,000 panels annually.

These kits are actually more expensive than the ones offered by Philips or OSRAM (although the OLED panel itself is larger). But at any case these are just 'samples', with real commercial panels expected at around 2013.
