I created a decent mod to my tikka. Imitated a cable similiar to the Arctic, cut a small notch in the plastic of the tikka, and connected the cables to the proper positive and negative. Now, on the other end, I have the same connector similiar to the arctic, and connected the unit to a 4.5 volt flat battery (popular with other Petzl products, zoom especially). Can't really post pictures of the unit...gave it to a friend.
Original battery life on 3 AAAs state 120 hours burn time (12h peak, 48h putter around tent, remainder for night reading)
. With the flat battery, multiply the above numbers by 5.
Plus the bonus that the cable is long enough to put the battery under your jacket, making an EXCELLENT winter light (as long as the battery is warm).
