I believe the blink mode is documented as extending the battery life, at least in the manuals I've read.

  The significant battery drain is driving the LED when it's on, so having it on only half of the time effectively doubles the battery life.

  That still doesn't explain the (rather common) lights with about 7 different types of blinking.
