White paint will actually reflects better than aluminum foil. 
Something proven again and again back in the sixties when lots of folks
grew plants indoor.

Highly polished aluminum can give even better results than paint(for
example the Miro material that AH Supply uses for its reflectors) and
the closer you get to a true parabolic shape, the better (again, like
AH Supply reflectors) -- with a parabola and a light source at the
center of it, all the angles of refraction result in the light going
straight out the front of the refelctor (or down in the case of an
aquarium light.  Aluminum flashing from Home Depot won't reflect better
than good white paint but it will do about as well as Reynolds aluminum
