The new models in Walther's Tactical Guard Series are all watertight with a rating of IPX8. They have two output settings based on the ANSI standard (100/10%) plus a strobe mode. The TGS60r emits an impressive 660-lumen beam. A practical clip is included, and a dual switch allows seperate activation of the functions. In contrast to the TGS60, which is otherwise identical in design, the "r" (rechargeable) version comes with a 18650 rechargeable lithium battery.However, its multi-battery system also accepts two CR123 batteries.
