I remember that in camp stoves, some are "dual fuel" which is Coleman fuel and unleaded gasoline.
The LED lantens I have over the years, not bright enough to be useful. One camping trip, I tried my LED lantern to walk from the camp fire back to my vehicle. Not bright enough. Had to get out my LED flash light and shine that down the trail.
Didn't have my Ozark fluorescent to try, but I think that would have worked fine.
