Okay, I realise this isn't case related, but it seemed like the closest to what I wanted to ask. Basically I want to make some LED Poi a little like these, but longer and brighter; I want ~20+ cm rods of light.

I was thinking of powering 4 x Super Bright LEDs per POI, but I'm not much of an electronics wiz. From what I've read, I can power these if I run them in parallel off 3xAAA NimH Batteries. The LEDs I've ordered can be seen here. Now I gather I need a current-limiting resistor, but I'm not sure how to calculate the value... can anyone shed some light on this for me / suggest a better way of doing this?

Many thanks in advance
