6v dc./sla. down to 3v dc to power a 1w.Duracell led flashlight that normally runs on 2 aa batteries or 12v to 3v.
this set up is for a bike light, I have access to a 6v sla. batt. that came from a larger flood light that was useless because of the power sucking halogen bulb,approx 15 min. run time.it also has its own charging circuit and a separate circuit for a single led night light.I tried looking up resistor values,but get confused cause i'm getting different answers from different sites ! LOOSING MY MIND ! HELP ! thanks oh..I use the night light circuit to power a red led flashing bike light for the rear.
