according to my notes, a V luminosity star can be anywhere from 1/10,000th 
to 1,000 times the brightness of the Sun, so first thing you need to decide 
is where the companion lines on that scale. It can be barely visible at the 
low end or as bright as the sun at the high end.

One reason that for my generation of stars I now set a magnitude and then 
derive the luminosity from that so I have a specific number rather than the 
very, very broad and overlapping catagories that luminosity provides.
