I would use this BuckPuck-700mA-4-wire instead of a resistor, but either should work fine.

so let me see if i understand

i use a 4aaa = 6v
Amber 151lm @ 700mA 3.2v
so i need the 4.7ohm, but has two one with 5W and one with 10W
witch one is the right?
whats the difference?

thanks

Two? 5w sounds ok.
