The E1D LED Defender Flashlight from SureFire is a dual-output LED light with self-defense features. It has a 1.13" diameter crenellated strike bezel and a scalloped tailcap shroud. The constant-on and momentary illumination modes can operate at two brightness levels: the 300-lumen high, and the 5-lumen low. Use the click-type tailcap pushbutton to switch between the modes and brightness levels. SureFire's Total Internal Reflection (TIR) Lens creates a pre-focused beam which has a bright and collimated center core with a dimmer ring on the periphery. The light features a Mil-Spec hard-anodized aluminum alloy body with an impact-resistant and anti-reflection coated window.
The flashlight is waterproof with o-rings and gasket seals. It comes with a two-way steel clip and a battery.
