The SureFire E2D Defender Ultra Dual-Output Tactical Flashlight is a premium everyday-carry tactical flashlight engineered for maximum performance, durability, and reliability in demanding environments. Precision-machined from aerospace-grade aluminum, the E2D Defender Ultra combines compact portability with powerful illumination for professional, defensive, and everyday applications.
Delivering an intense 1,000-lumen high-output beam, the E2D Defender Ultra is capable of disrupting an attacker’s vision while providing excellent target identification at extended distances. Its advanced Total Internal Reflection (TIR) lens creates a focused center beam with ample peripheral spill light, helping maintain situational awareness in low-light conditions.
For administrative tasks and extended runtime needs, the flashlight also features a 5-lumen low-output mode, ideal for reading maps, checking gear, or preserving night-adapted vision. The rugged Strike Bezel® and scalloped tailcap add defensive utility while enhancing grip and handling.
Finished with a Mil-Spec hard-anodized coating for corrosion resistance and long-term durability, the E2D Defender Ultra is built to perform when reliability matters most.
