Re: Best way to drive 3 LS\'s?
I'd wire all three LS in series, and drive them with 4x123. You also might need a small resistor in series to limit current flow to whatever level you wanted.
Getting a little more sophisticated, you could use 5x123 or even 6x123 and run all three LS in series, but instead of the resistor use an LM317 regulation chip (costs less than a dollar) plus a resistor to make a constant current regulator. That would be neat! /ubbthreads/images/graemlins/smile.gif
