I've still got one of those - a 2D Maglite modified to run a projector bulb off a rechargeable battery packI don't know if they were part of it but there was a whole torch modding scene a few years back. Usually used "C" & "D" cell Maglite® bodies as donor units and they'd rewire and trick out with gold electronics, frensel lenses, fancy reflectors and high end bulbs. Some got so powerful that they would cook eggs when pointed at them and the beam could also set newspaper alight when directed onto it. There were whole forums & websites dedicated to it.

You could set light to newspaper with it (from about 10mm in front of the lens)
