Does anyone know how the LEDs are driven in the 4AA Propolymer?
I'm in the market for a 2 or 4 cell AA powered Luxeon flashlight that does not drive the LEDs using a simple series resistors as they use the batteries ineffectively.
From experience, my Brinkmann cylindrical flashlight has a high frequency driver circuit while my cheapo 5 LED bike light has a series resistor with each LED.
