I use the good ole coleman lantern, remember as with anything that burns gas produces carbon monoxide, so always vent your shanty, I was ice fishing in the early 80's had my shanty up, coleman on high and after about 3hrs on the same hole with good luck, caught myself getting sick and very tired, stepped out for some fresh air and thats when I realized that I was getting sick on the fumes. So now I always leave the flap open at the top.
