Pi_is_blue,
You can use 3AA to drive our MC, Super6, or Trilight products, briefly. If you drive or 2AA adapter with 3AA, you will certainly let the magic smoke out of the electronic device, and probably pretty soon. Other companies are happy to overdrive their LEDs, we are happy to have a product that will last a long time.
Designing a new flashlight to handle 3AA properly is something we could do for a lot of money and not much advantage. There are a LOT of Mini-MAG flashlights out there. Plus, we like the Mag Instruments product line.
