EFKE/Adox 100 is the ISO speed for Tungsten light, in daylight it's about a 2/3rds to a stop faster 160-200 EI, the same goes for the slower films.

These aren't old style films though quite the opposite they were the first if the modern thin coated emulsions. Being single emulsions they don't have the latitude of films from Ilford, Fuji and Kodak when it comes to push processing.
