Get the Primus EasyLight Lantern.
490 max lumens.
Piezoelectric ignition so no need for matches.
Burn time of 4-36hrs depending on how bright you need it and the size of canister used.
Since your using a gas canister, why not bring your pocket stove and cook a meal too.
Cost of canisters will be about equal to cost of batteries.
There are also models that can be run off a standard 16.4oz propane tank. So the cost of tanks/runtime will be far better than a battery operated lantern.
