Yes to all.....
Yes I mean those mantles, yes I know they are easily found, 40 pack on the Amazon for $12. I am just VERY underwhelmed by the light out put and longevity of the piece. as I begin playing with them. I do not expect clinical white light and LED type output, but the typical coleman camp latern is significantly better and longer lasting than the propane wall fixtures seem to be .... I will live with what it is, I am just willing to buy the right stuff if there are tips and tricks out there. The thorium is an interesting and nice tip.... I weld with 2% thoriated tungsten, I assume the laterns won't be worse than that for gerenal healt risk !!
I do have several good oil lamps, as well as great modern headlamps and LED worklights, but the cabin has it own ambiance with the propane and wood stove... trying to get my things right!!! Thanks for the input so far.
