Cree, the makers of LEDs used in many flashlights, says that one of their lines of LEDs is protected to 2kV ESD.

Incandescent light bulbs are also vulnerable to surges. Based on lamp life formula, which has a very high exponent (a couple sources put it at 12 or 13.1), destruction of a 3V lamp during a 3000V surge is virtually instantaneous (far less than a nano-second).
Cree, the makers of LEDs used in many flashlights, says that one of their lines of LEDs is protected to 2kV ESD. Under a 50kV/meter EMP, this voltage can be induced on a wire or conductor 1.6 inches long.
