Compact (pocket sized), dual-output SureFire® E2D LED Defender® flashlight is designed for self-defense and personal protection. The E2D LED Defender® features a solid-state, two-stage light emitting diode that generates six times the output of a typical two-D-cell flashlight at its high setting and five lumens of useful light (enough to read a map or negotiate a dark path) on low. And should 120 lumens of blinding light not be enough to convince an aggressor to back off, the E2DL's crenellated Strike Bezel® and scalloped tailcap provide two sets of hard-anodized aluminum "teeth" as a last line of defense. Two useful output levels, a long runtime, a hard-anodized durable exterior, compact size, and enhanced personal protection capabilities make this flashlight a great everyday-carry option. Especially for those looking for a self-defense light with a bit more of a bite.Coated Pyrex® window protects the LED and lens while maximizing light transmission..Two-stage tailcap switch: press for momentary-on at high setting, release and press again (within two seconds) for momentary-on at low setting; click for constant-on at high-setting, click off and click on again (within two seconds) for constant-on at low setting..Patented lockout tailcap prevents accidental activation..Max Output: High 200 Lumens; Low: 5 Lumens..Runtime: Low 76 hours; High 1.9 hours..Length: 5.40 in..Weight: 3.70 oz..Batteries: Two 123A Lithium (included)..Made in USA..
