Thanks to the concerted efforts of several multi-lingual readers, Lighting 101 has been released in two more languages: Romanian and Russian.
The Romanian team included Christian Vladoaica, Anica Pandrea and Andrei Botesteanu. The Romanian translation can be retrieved as a pdf here, via Mediafire.
The Russian team included Dmitry Mayorov, Irene Ponomarova, Kosmynin Ivan and Max Polivanov. The Russian translation can be retrieved here.
Many thanks, in many languages. (And cool design, on both!) More L101 translations are in the pipeline.
