The Fraunhofer Institute first announced their Tabola OLED lighting panels back in October 2010, with plans to release them in Q1 2011. We haven't heard anything since (and I assumed the project was scrapped) - but last week I got a nice surprise in the mail: three sample panels (two transparent, one structured). The Fraunhofer are now producing sample panels and have actually started to ship these cool transparent Tabola OLEDs to customers now - which makes these the first transparent OLED lighting panels on the market. Read on for our hands-on review.
About the Tabola panels
Fraunhofer are offering Tabola panels in three sizes: a large rectangle (the T157, 150x76 mm), a small square (the T77, 75x76 mm) and a small rectangle (the T37, 75x31 mm). The panels themselves are either transparent, opaque or structured (i.e. opaque panels with a custom logo or lettering). The opaque panels are available in a colored or white (3200K) versions. The panels are not very efficient (the transparent white modules's efficacy is about 12 to 18 lm/W, depending on the module size) and they feature a typical CRI of 90, and an average transmittance of 45% (at 550 nm).
