    Could you tell us more about the LED you used. What voltage? Was it a standard or superbright? I couldn't tell how many AA batteries were in your pack, 2 or 4. That will determine the voltage applied to the LED. Just curious about details.

    Im not sure if my last reply went through.
    The led I used was a 5mm bulb that has a 3.4-4.0V forward operating voltage.
    The battery pack used 2 batteries.
    Thank you for showing interest in my first instructable!
