SUREFIRE is set to release a head lamp sometime this year called the "SAINT".
here's what really impresses me about it.it is what they call "DUEL-FUEL" capable.meaning it can use either standard AA batts. or 123A LITHIUM batts like the majority of surefires use.
its sometimes hard to find 123A's in the field but AA's can practically be found anywhere.
is this a first of its kind thing??
