The Surefire EB1 Backup is one of the best backup lights for patrol officers or a duty light for plainclothes officers. The Surefire EB1 Backup flashlight is extremely compact has a dual output that shines a 200 lumen LED bulb on high. On low is just enough light at 5 lumens, to see a few feet in front of you. This flashlight is ideal for everyday carry, self-defense, or outdoor applications. Virtually indestructible LED emitter and a precision Total Internal Reflection (TIR lens, the EB1 creates a beam of light with the perfect configuration for both reach and situational awareness.
The Surefire EB1 Backup has three models to choose from, differing in the tail cap type/switch type combination:
Click-type switch with tail cap shroud — Partially press tail cap 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. The raised shroud around switch provides extra protection against accidental activation.
Click-type switch without tail cap shroud — Like the original E1B Backup. Partially press tail cap 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. No shroud around switch.

Tactical switch without shroud — Partially press tail cap pushbutton for momentary-on low output; press further for momentary-on high output. Release to turn light off. Twist tail cap clockwise for constant-on low then high output. No shroud around switch.
With the sure bright 200-lumen high output beam, the Surefire EB1 Backup is ideal for identifying threats and overwhelming the sight of your adversaries. The low mode of just 5 lumens is great for reading a map, check an ID or navigating in low light without degradation of your dark-adapted vision. This flashlight runs on the low mode for up to 40 hours, great for emergency situations too. The body is touch, lightweight mil-spec hard-anodized aluminum, which protects the sophisticated electronics housed inside. It comes with a belt clip and all the models are available in Black, Silver, and Desert Tan colors.
