The US Embassy in Helsinki is installing an Acuity Brands Trilia OLED fixture in their Innovation Center. They posted this nice photo showing the work in progress:

The Trilia is a modular lamp that uses either two kinds of models (the Tri and the Straight) to create unique network-like design. The Tri section model uses 24 OLED panels (1810 lumens) while the Straight section model uses 8 panels (603 lumens). This specific installation has 136 OLED panels altogether.

The OLED panels (produced by LG Chem) feature an efficiency of 60 lm/W, 3500K color temperature, 15,000 hours of lifetime (LT70) and a CRI of over 80.
