OSRAM announced a new OLED lamp for car interiors - the OLED Reading Light. This is a single OLED lighting panel placed in a high-quality matt aluminum housing that provides a very warm (3300 kelvin) and uniform light. This is an after-market product, with a clip at the back of the panel enables it to be attached to the sun visor. It can be charged via a USB cable.
OSRAM says that OLED lighting is ideal for applications in which the eyes have to focus on one point for a long time thanks to its homogeneous light that does not dazzle or cast shadows. Unfortunately OSRAM did not reveal the OLED panels` spec, but they do provide a 5-year guarantee so it means that the lifetime and stability is probably quite good.
