The ballast should say on top what lamps it will work with, or you can
look up the specifications at its manufacturer's web site.  I do know
that an F40T12 ballast will operate some 36W compact fluorescent lamps
(the long twin tube lamps that are 16.5" long), and an F32T8 or F40T8
ballast will operate the 36W - 40W compact fluorescents that are 22.5"
long.  The lamp operating characteristics are *almost* identical to what
the ballast was designed for.  You may lose the UL or CSA safety rating
for the ballast if you use it with a different formfactor lamp than it
was intended.

Best regards,
