Efke IR820 AURA and No. 5R Infrared Flashbulbs

[brianmquinn]

I picked up a few of old GE No.5R Infrared Flashbulbs and would like to try out this combination. The GE No.5R lists a guide number on 55 for use with IR film. But this was Kodak IR film from the 1950s. Does anyone know where I should start with a film I can still get (does not have to be EFKE). I would just do my own experiments but I have few bulbs and do not want to use them all up on testing.

I wanted to do the same thing, but I haven't quite gotten around to it yet.

Mr Kohei Yoshiyuki would be proud.
