The Polysteel 600R LED Flashlight is the first in the Polysteel line to add rechargeable capabilities to the mix. The flashlight is equipped with our Dual Power system that enables the light to run on either our custom rechargeable lithium-ion battery pack or standard alkaline batteries. The rechargeable battery pack also features a charging port that allows for the external charging of devices that standard USB inserts. The Polysteel 600R is waterproof, drop proof, and crush proof while possessing our Pure Beam Optics System with twist focus to make the light ultra durable and ready to weather any storm. With a stainless steel core and a poly outer, we put this light to the test, and it passed each one with style.
