OLED lighting based emergency lighting has been suggested back in 2009 by Kenwood, and later in 2010 by Novaled and Willing. But now we finally have the first commercial product, the ETAP K4, in which the pictogram is the actual illuminating OLED surface. ETAP collaborated with Philips to enable this product and are using Lumiblades panels. The K4 is now available and it's about 40% more expensive then ETAP's high-end LED luminaire.
The size of the emergency panel is 227x134 mm, and it is 4 mm thick. The lit area is 210x105 mm. The panel should last for 10 years (the lifetime is 35,000 hours, LT70), and ETAP provides a 5 year warranty. The efficiency is 40 lm/W (this is based on Philips' Lumiblade Plus, developed by Konica Minolta).
