I've been able to get seeable fringes from an aluminized flat with a clear
uncoated flat on top of it with just ordinary cool white flourscents.  In
an enclosure with a green light, the fringes appear without any problems. 
They are dimmer than glass/glass fringes but are quite visible
nevertheless. One thing to note is that the glass and aluminum does need to
be clean and DRY.  If you wash the surfaces, leave them ot dry for a good 5
minutes or the outgassing of the water will keep the fringes from forming
as there will be too much of a gap for best results.  In addition, any dust
wll keep the fringes from forming as well.
