I work for the government as a communication technician and sometimes you need a nice bright light with stay power , when work in dark room and do cable splice , etc. . so , I know what I be get before I actually buy one of these light for myself . I be so impressed with the light at work , that I know I would eventually have one at home , and now I do . this be a great light ! it will stay light for hour without need a charge . no battery to replace and super bright . my light come with 2 mount bracket , a ac charger and a dc plug for the car or truck . I 'll definately pack this light during future trip . also , I receive this light just 3 day after order it . . super fast delivery !
