SUREFIRE makes a great light. 2 or 3 times brighter than any MAG or the like. (The batterys are 12-15 bucks tho). It is small, very light, has a twist bottom so it doent turn on in your bag and the best part..the DEFENDER model fits in your hand so both ends stick out each side of your palm and the light has a strike bezzel? so you can knock that crazy captain upside the head and wake him up!
