Ya, that's pretty cool, but I actually burned a hole in an old car seat by accident with my rechargable mag light. In fact, I had a strap on a backpack instantly catch on fire, the moment I set the maglight next to it, while left turned on. It has to do more than just with the power output of the light. If it were just output, the headlights and spotlights on our trucks would set the woods on fire as we drove down the trail, but that doesn't happen.

What is likely causing that light to set things on fire is what caused my Mag light to burn up my seat and backpack strap...the focus beam of a small lens. Essentially the same thing as using a magnifying glass and the sun to set things on fire.

That is still an impressive light, because focus beam or not, it still packs a lot of power. I would imagine it gets pretty hot and isn't very practicle to hold for even brief periods of time.
