The PolyTac X USB Flashlight is a 600-lumen multi-fuel illumination tool built for durability and a secure grip. Constructed from high-impact black nylon polymer, it features an O-ring sealed glass lens and a tactical push-button tail switch. This model operates on either two CR123A lithium batteries or the included Streamlight SL-B26 protected Li-Ion rechargeable battery pack, which features an integrated micro-USB charge port. TEN-TAP programming allows users to select between three modes: high/strobe/low, high only, or low/medium/high. Delivering a 205-meter beam and a runtime of up to 36 hours depending on the battery used, it includes a removable pocket clip and a USB charging cord.
