So whats the advantages of a Seoul P4?

Nova has it right. I believe the stated 1000mAh he has is the buckpuck though. 4AA is vague... most NiMH and alkalines are around 2400mAh in AA size so I'd say 2 1/2 hours for sure. You'd get a little more with Alkalines vs. NiMH because of the voltage difference too.

Your batteries may be different, but the AA NiMH batteries I have are 2650 mAH. If you are pulling a straight 1A out of them, theoretically, they'll last for 2.65 hours. I don't know at what point they'll drop below the forward voltage of the LED though. The puck will make adjustments to keep the LED going as long as possible.

If you are running a driver with PWM, it would probably last longer, but I have no idea how much longer. Some day, I'd like to charge up my sabers and leave them on, just to see how long they last.

Edit:

You two beat me to it while I was typing. LOL!
