The "DFT" stands for dual fuel tactical, and represents the natural evolution of our best-selling Fury Tactical flashlight into a single-output 1,500 lumen light that can also function as a searchlight. The dual fuel feature means the light can be powered by either two 123A lithium batteries or a single economical 18650 lithium-ion rechargeable battery. Press or click its tail cap switch for ergonomic, foolproof activation under even the most stressful conditions. Its precision micro-textured reflector shapes a smooth useful beam that is far-reaching, with a bright central area that is also optimized for situational awareness. The high-strength aerospace-aluminum body and tail cap are knurled for a secure grip and it is Mil-spec hard-anodized to resist abrasion and corrosion, so you never need to baby it.
