Mine do.  I replace them when they get hard to start.

If you have the installation instructions for your ballasts you might
check and see what they say.  A couple of mine specify that the lights
should be mounted within 1/2 inch of a ground that runs the full length of
the tube.  That's to help with starting.  Usually it means that you need a
grounded metal reflector.  It might be that when the lights are new the
ballasts can start them dependably, but as they get older the ballasts
needs the help from the grounded reflector.
