I have have a five d-cell maglite since 1986 and it be still work great ; I have only have to replace two lamp within that time . I be a scoutmaster for year and the boy call my flashlight , `` the Sun '' . when they would try to sneak off I could always find they ... the flashlight light up the whole mountain or I could narrow the beam and spot a boy nearly a mile away . I buy this six-celled maglite because I be tire of always have a lone battery with my five-celled light because battery be not package in odd number . that in fact be my recommendation to you to buy a six-cell maglite rather than a five-cell so you do not have a odd battery go to waste . I now have two great flashlight one be under my bed and the other be on my refrigerator where they be always available for emergency and light up the whole dang town if I have too : - -rrb-
