If you search the Philips and Osram European Web sites you may still
be able to find lamp operating currents for a limited number of lamp
models. For some reason these companies believe that their European
customers are more interested in lamp technical data than customers in
NA. On the other hand, GE has started publishing rather complete data
sheets for some of their newer lamps, and some may have operating
currents. However, as you have determined, the very best source is the
two IEC specs and their addendums.

If you live near a college that has a lighting program you may find
these specs in their library. I know that the LRC library has copies.
UC Boulder and Penn State also have lighting programs, but I don't
know if they have the IEC specs in their library.

You might wan to search scholar.google.com, a new version of Google
that accesses technical papers. It is really quite interesting.
