I use a MAP torch made by MagTorch that is self lighting. I got it at Home Depot, kit cam with 3 torch heads, 2 tanks, and plastic storage case. Same as propane, except yellow tanks, burns much hotter.
Been using it for over a year, originally bought it to burn out the bushings in my F250 left springs so I could replace them. Used it for lots of stuff since, including lighting AMPS, 1st tank it just now running out.
