This light package contains a PL350 Pistol light switch and body assembly, and the PLHv2 Head. It also includes a single 18350 rechargeable batter, a set of PHLSTER ARC Switch Paddles, and a 2 Cell XTAR USB charger. A defining characteristic of the PL350 is its "Out the front" battery change ability which allows the user to quickly replace discharged batteries with fresh ones, without tools and without removing the pistol light body from the host weapon. The PL350 is designed to be compatible with current and future Modlite heads, ensuring long life and future upgrade paths.
