Exposure times

I just found this great link!  People documenting exposure times in their areas and homemade light boxes (with types of bulbs).  Of course it is still very variable and requires experimentation.  A full day to expose a print in CA?!

For me, in New Haven, it has taken from 5 to 20 minutes depending on time of year and weather.
