Surefire E2D Ultra Defender LED Flashlight with 2 CR123A Batteries - Aluminum Black

The Surefire E2D Ultra Defender is a compact LED flashlight engineered for serious everyday carry, whether you're a working professional, outdoor enthusiast, or anyone who needs a dependable light they can trust. Built from aerospace-grade aluminum and finished with Type III Mil-Spec hard-anodized coating, this light is designed to endure hard use in harsh conditions—moisture, dust, and rough handling won't slow it down. At just 5.6 inches long and 4.2 ounces with batteries, it slides easily into a pocket or pack without complaint, yet delivers the output and runtime you need when darkness falls or an emergency hits.

The E2D Ultra's dual-output system gives you real flexibility. High output delivers 1,000 lumens of intense, precisely focused beam through a Total Internal Reflection (TIR) lens—enough to illuminate a large area or temporarily overwhelm a threat. That high-output mode runs for a minimum of 2.75 hours on two CR123A batteries. When you need something lighter for close work—reading a map, navigating camp, checking gear—a second click drops you to 5 lumens, and at that level you're looking at 63 hours of runtime. The push-button tail cap is intuitive: one click for high, two clicks for low.

The design also speaks to durability and purpose. The crenellated strike bezel and scalloped tail cap aren't just aesthetic—they're functional elements that reinforce the light's structure and give it a secondary role as an impact tool if things go sideways. The dual-function pocket clip works bezel-up or bezel-down, fitting your carry preference and clothing type. This is a light built by people who understand that gear needs to work when it matters.
