Dear Rafael,

Look in the alt-photo-process archive (When I remember well : 
http://altphotolist.org) at the date 07-Feb-2007 : Light source for 
contact printing.
Useful lifetime : 500 hours officially. Kees Brandenburg used them more 
than 10 years !!.
In Europe we use 230 Volt. Exposure time :5 - 10 minutes.

              Kind regards

                 Erich
