Interesting what you both said about 75w incandescent.
While once readily available here in the "A" shape the way I remember it people generally used either 60w or 100w.
75w always seemed to be lost in a gray area so to speak.
I guess that's why when I look for incandescents online I find so many 75w and why I now have to many of them
However 75w was the standard in the common R30 but I'm not sure what the European counterpart is to the R30.
