super flashlight! will burn you in a matter of seconds (V)

Just so we're clear that the radiant heat, not the light which is igniting it.

 

MW lazers would do a better job IMO, and have range over the flashlight. and the beam would be hella stronger than that of a flashlight, but for xmas trees, the widness of the array, might be better.

but a 50MW lazer i think it is can easily melt plastic.
