The US DoE published a new CALiPER report made by the PNNL laboratory, with photometric testing, laboratory teardowns and accelerated lifetime testing of OLED luminaires. As you can see in the photo below, the four luminaries (from top-left, clockwise) are the OTI Aerelight, Acuity Brands Chalina and Acuity Brands Nomi (single panel and dual panel).

CALiPER 24 OLED luminairies

The report contains a lot of interesting information (see the link below to access the PDF). The PNNL researchers find that efficiency of OLED luminairies is still low compared to LED lamps - ranging from 23 lm/W to 45 lm/W. The OLED panels themselves are more efficient (42 - 55 lm/W) but the reduction in efficiency is mostly due to very inefficient transformer and driver selections and combinations.

In terms of color quality, PNNL finds that the OLEDWorks panels are somewhat lower compared to the panels made by LG Display. Overall, though, those luminaires performed very closely to the available manufacturers’ published technical data.
