A traditional light bulb of lamp manufacturer Osram is pictured in Germering near Munich November 28, 2012. Siemens AG is expected to publish details of the long-awaited spin-off of Osram on Wednesday after its supervisory board meets to set out a future course for the lighting unit. In a separate meeting on Thursday, Osram's supervisory board is expected to approve plans for a restructuring programme costing 500 million euros and thousands of jobs, sources have said. Osram, whose brand is 106 years old, has been slow to adapt to a shift from traditional light bulbs to more energy efficient and durable light-emitting diodes (LEDs).
