I use a propane lantern. They put out more light than any battery powered light you can carry. Almost all of my tracking jobs are at night, so I've done a quite a few of them. I was buying those cheaper Coleman lanterns with 2 mantles, but I would have trouble breaking mantles and the top wouldn't stay on straight and I was also breaking globes. Then I got a North Star lantern also made by Coleman. I'll tell you, this is a great lantern. I think it was about 50 bucks. It has a larger mantle, but it is a single mantle and is fastened at the top and bottom. The globe has a guard around it and when you tighten down the top, it tightens against the guard and not the globe. That allows the globe to sit inside the guard without any bind on it at all. I have had this lantern for at least 3 years and I haven't replaced a mantle yet, nor have I had any other problems. It is well worth the extra money. I also use it around here on the farm in the winter when lambing. It will almost warm up a small room, too, lol.
