Acuity's Canvis OLED lighting can be hung vertically or anchored to both wall and ceiling. Because OLED lighting lacks the intensity of incandescent, fluorescent, and LED lighting, it can directly illuminate rooms without any need to diffuse or reflect light.
Acuity Brands' Nomi is a slim wall-mounted sconce with an OLED lighting panel. The center view shows a configuration that illuminates rooms directly; the right view also has a backward-facing OLED panel that reflects light off the wall.
The Kindred OLED lighting comes in a ceiling-hung configuration and a table lamp. Because OLED panels aren't piercingly bright, table lamps can be placed near work or reading areas with to provide direct illumination.
