Typically with a 12v power source you would need to add resistors to get the proper power to the leds, I'd TRY it without the resistors at the lower voltage and see what happens. If you're running a premade strip of LEDs then the resistors will be built in already. Run 10 AAA batts in a series and see what happens... If you apply less than 12 volts I highly doubt you'll damage the leds. If you put over 12 volts, you could. Give it a shot.
