For Executive Series flashlight lamps and P-series lamps with integral reflectors. This Impact-resistant, watertight polymer container provides storage for one spare lamp assembly and six 123A lithium batteries. The SC1 is a -Inchmust have-Inch item for prepared individuals. Batteries and lamp not included. *NOTE: Due to their smaller size, Executive Series lamps do not fit snugly in the SC1. SureFire recommends that Executive Series lamps be surrounded with a user-supplied buffering material, such as plastic foam or cotton, to achieve a snug, rattle-free fit.
