Regulator. LM 7805. Best option.

Here is an instructable using a DC to Dc converter:

The data sheet says the input voltage can be 4.5 to 14 volts. The output can be adjusted from one half volt to 6 volts. Murata makes several different devices for different current / wattage requirements;

a linear regulator is the cheapest option - not the most efficient - there are digital switching supplies that bump the voltage up or down (boost or buck) at near 95% efficiency, where the lm7805 burns off more than half the energy to drop the voltage down to the required level. Just a thought.
