this be my favorite mag-lite purchase . those of we who have use the Mini-mags over the year have learn to live with dim light and unexceptional battery life , but gladly trade that for its durability and quality construction . this light change all that . unlike led upgrade -lrb- and even the maglite c and d cell lead light -rrb- , this flashlight be design to be use with a lead bulb , which be evidence by its elongate head . the result be a very bright light , with almost no `` black hole '' when on wide flood . its output be very similar to the regular -lrb- krypton -rrb- 3 c\/d cell light , but in a much smaller package . what be interesting be the proportion be similar to the 6d cell , which give it some use as a defensive weapon , for those so inclined . I do have a gripe about the pricing - $ 10 less would be nice . however , it be make in America and it be tough as nail . my only caveat be this be at least 30 % longer than the 2aa mini-mag , and therefore do not fit quite as easily into purse , pocket , & c. but lighting and battery life be significantly longer .
