SureFire E1D Defender Dual-Output LED Flashlight Review


Small enough to fit in the palm of your hand, the SureFire E1D LED Defender Dual-The E1D LED Defender® is an ultra-compact 300-lumen flashlight featuring dual-output capability and self-defense enhancements. Utilizing a virtually indestructible high-performance LED and a Total Internal Reflection (TIR) lens, the E1DL is activated with a pushbutton tailcap click switch that also permits the selection of output levels: press or click once for a high-intensity 300-lumen white-light beam—more than sufficient to overwhelm the dark-adapted vision of an aggressor. Return to off and press or click again within two seconds for a 5-lumen long-runtime low beam that’s suitable for navigating at night or performing close-up tasks for up to 47 hours.

The Defender’s crenellated Strike Bezel® provides further defensive options should the need arise. Ultra compact and powerful, the E1DL is an ideal everyday-carry light.


As technological advances push the boundaries for product innovation, tactical illumination has become a principle component of the tactical enthusiast and that technology has resulted in a variety of brands and products available on the market today.  Surefire is one of the pioneers of tactical illumination and their products have set a standard that many other manufacturers have yet to achieve.  The E1D Defender is no exception and is a perfect example of the level of craftsmanship, design and quality materials employed by Surefire to produce one of the most reliable tactical lights on the available today.  

The Defender model has been part of the Surefire lineup for over a decade and remains one of the best compact tactical flashlights in that price range.  Not to mention, all Surefire lights are made in the USA and therefore, their products’ construction and materials are of the highest quality and take pride in providing products for U.S. Military and Law Enforcement divisions for their illumination needs.
