small, very handy and powerful lamp ... the weakest light modes can do without me, if someone for example. characterize his backpack wants to, he can perhaps use it, then he will find it in the dark .... but the best part is the clip. you can turn it over and attach the other way around. then I can put him on the cap Schilld (see photo) .echt handy if you want to have your hands free .....
