I really like the cabelas Alaskan guide xpg head lamp. It seems a little bulky but its balanced nicely. Has 4 different light settings. White and green, bright and dim. It will put out 200 lumens, which I think is plenty. And it's a pretty focused beam so it has great ditance. But 200 lumens for 70 hours is great or u could do 40 lumens for 150 hours. For 89$ it's a little pricey, but being cabelas brand if anything were to go wrong with it u can exchange it.
