that be right . I buy one of these light , previously own one of they mini-mag . I see the quality of product , and base upon that and its reputation for be the most rugged light out there I buy the 4d . I be not disappointed , this light be like a light cannon . upgrade to the xenon bulb make a whiter light than stock , and be slightly brighter . mag also make different lens for the larger -lrb- 3,4,5,6 d cell -rrb- light , as well as anti-roll cap cover . so kid , tell you parent `` buy I a Maglite -- or go to hell !
