I just recieved my P1 from Fenix, incredibly small,extremely bright light. It runs on one C123 cell. It would blow an Arc AAA away. I also picked up Brinkman 3W LED from Target for my Dad. Very nice light running on 3 AAA. Good throw with a nice smooth flood. Dorcy also makes a decent 1W LED running 3 AAA. Have a nice day :-)
