The EB1 Backup is an extremely compact dual-output flashlight with a 200-lumen maximum output that can be used as a 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 EB1 features a virtually indestructible LED emitter and a precision Total Internal Reflection (TIR) lens, creating a beam with the optimum configuration for both reach and situational awareness.
Click-type switch with tailcap shroud — Partially press tailcap pushbutton 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. Raised shroud around switch provides extra protection against accidental activation.
The brilliant 200-lumen high output beam is ideal for identifying threats and overwhelming the sight of adversaries. The 5-lumen low output is perfect for reading a map, checking an ID, or navigating in low light with minimal degradation to your dark-adapted vision. The Backup can run at this level for 40 hours, a valuable feature for outdoor or emergency situations. A tough, lightweight Mil-Spec hard-anodized aluminum body protects the EB1 Backup’s sophisticated electronics, and its smooth contours minimize clothing snag and pressure points. A two-way clip allows head-up or head-down carry
