Surefire EB2 Backup 500 Lumen Flashlight Click Switch - Black


The Surefire EB2 Backup is a slender, compact dual-output flashlight with a stunning 500-lumen maximum output that can be used as a primary or backup light for patrol officers or a duty light for plainclothes officers. It's also ideal for everyday-carry, self-defense, or outdoor applications. The Surefire EB2 Backup features an ultra-high-output, virtually indestructible LED emitter and a precision Total Internal Reflection (TIR) lens that create a high-intensity beam optimized for both reach and situational awareness.

Click-type switch - Partially press tailcap push-button for momentary-on high output press further to click constant-on high. Return to off and press or click again within two seconds for low output.

The Surefire EB2 Backup's max-output 500-lumen beam is ideal for identifying potential threats and overwhelming their vision. Its five-lumen low-output setting is perfect for reading a map, checking an ID, or navigating in low light with minimal degradation of your dark-adapted vision. The Surefire EB2 Backup can run at this low-output level for 67 hours on a set of two 123A lithium batteries, a valuable feature for outdoor, emergency, or other uses where you may not have easy access to spare batteries.

A tough, lightweight Mil-Spec hard-anodized aluminum body protects the Surefire EB2 Backup's sophisticated electronics, and its smooth contours minimize clothing snag and pressure points. A two-way clip permits secure head-up or head-down carry, as well as field-expedient hands-free lighting if clipped to the bill or brim of a hat.
