I have used light bulbs in the olden days, although not for the K3 cal
procedure. The trick is to insert a variable cap in series to tune out
the reactance. Works well, but has to be retuned for each band of
course, and the resistance varies with brightness. Because of the
variation, do not use with an automatic antenna tuner or the tuner
will constantly seek a correct tune. 

A real dummy load is better.
