To be honest I have not really tested range. I chose 3x AA because I wanted to use NiMH and so with 1.2v per cell it made more sense to me to use 3 for maximum power.
The other thing is mine doesn't use the same LEDs as in the official kit, as I couldn't buy them in NZ, so that may change the range too.
