Halogens are typically rated at 2000 hrs and 12v.
With a little experimentation, you could find a resistor or regulate
the power to keep them at 12v. Running more than 12v. will
definately shorten their life and they usually arent cheap either.

If you want to regulate the voltage, you can pick up a 12-volt regulator
(it's either a 7812 or a 7912 - one's positive, the other negative and I
don't recall which is which) at any electronic parts store. Cost should be
under $1. You'll need a couple of capacitors and resistors to complete the
job. Potting the entire circuit in an old 35mm film canister provides
corrosion protection.
Hope this isn't stating the obvious!
