Depends on how long the run is. If it's 15' 12 gauge would be the smallest I'd use.

I said he could, not that I would!

I'd agree that 12gauge is what I'd use, but thats if its really 15 feet.
14 ga if its a shorter run I would think would be fine. Its not like youre gonna burn out either wire from that current, but if you want to supply it with as much power(which may translate to brightness) then why undersize your leads, do it right the 1st time

Interesting calculator. Their resistance figures per 1000' are more conservative (higher resistance) than what I use.
I wonder if their wire is fewer strands than is typical with automotive wiring. Mine are based on automotive wiring, so that might explain the lower resistance.
