I have powered 'LUXEON Rebel ES 3W High Power LED' with just x2 AA batteries. It works, but I know it is wrong.
Voltage: 3.2-3.4V
Current: 300-1000mA
How should I be powering this LED if I want it on an item for a couple of hours at a time?
I can't find any tutorials on this
any help greatly appreciated!!!
