On what OS is this?  If it's MS-Windows, then the 'light' weight is
not really supported, because the Windows API that enumerate fonts of
a given family don't consider 'light' to belong to the family.  They
only recognize 'regular', 'bold', 'italic', and 'bold-italic' as
members of the same font family.
