if i remember correctly the green ones take 1.3 volts for full brightness so 4 times 1.3 = 5.3 volts in series now if you wanted you vcould put them in parallel and it would only take 1.3-1.4 volts to run all 4 but the current is gonna be x4 i think that is the right voltage for the green ones it has been a while since i have messed with the green ones but the voltage and the current draw should be on the package just look around on it and see if you see any thing glad to help with any thing gotta run
