Deutsche Bank's Berlin office installed a huge OLED chandelier that has 384 Philips Lumiblade panels. It's quite beautiful:

The chandelier consists of 24 square frames (made from shiny chrome aluminum) that are suspended in a column around a pole of dichoric glass. Each frame holds 16 rectangular OLED panels, so in total the chandelier has 384 OLEDs (or 2.4 square meters of active area).

The chandelier was designed by Kardorff Ingenieure Lighting Design. Great work guys, this is one of my favorite OLED lamps...
